Right-handed or Left-handed? How Early Can You Tell?

Being a lefty, I know all about the inconveniences of being one of the 10% (or so) of adults who are left-handed. Of course, I know there are stories about “lefties,” specifically, how our brains work differently than those of our righty brethren. The stereotype lingers that lefties are creative but a bit scattered, illogical and spacey. Ok, the spacey part might work… But, how do babies become right- or left-handed and how soon can you tell which hand your baby will prefer? In this post, we want to share some of the research in this area.

How Do Babies Become Right or Left Handed?

Scientists do not fully understand how babies end up favoring one hand over the other. A few ideas have been tested related to babies’ positioning in the womb. Because of the limited space and the position of maternal organs, developing babies end up looking to the right more often than to the left. This means that they are more likely to see and become familiar with their right hands. Another idea relates that there is more likely to be space in the womb to move the right hand versus the left. If one hand is easier to move around, it may end up as the preferred hand. Some scientists have focused on factors influencing handedness after the baby is born. Typically, newborns do look to their right more often than their left and they will work to move the hand they see. This may result in earlier voluntary movement of the right hand. Another theory relates to the fact that babies watch and learn from their parents. Babies notice which hands are used to feed them, play with them etc. This theory may partly explain why left-handedness tends to run in families.

So, the current thinking is that most babies become right-handed because of several circumstances that slightly but consistently increase in the likelihood that they will see, explore, and use their right hands both prenatally and postnatally. We lefties either didn't have these experiences or reacted to them differently (perhaps that's where the brain differences come into it).

How Early Can you Tell if a Baby will be Right or Left Handed?

Many parents start to imagine that their baby is left- or right-handed based on the percentage of time their 4- or 5-month-old reaches awkwardly with one hand or the other for an object that is held in front of them. But simple one-handed grasp actions are easy to do with the non-dominant hand (you do this every day) so trying to identify the preferred hand so early isn’t likely to be very predictive (at least not of left-handedness because nearly all babies end up right-handed). Handedness becomes more predictable when babies start to use both hands to explore objects. Older babies will use one hand to grasp and the other to keep objects steady or to manipulate them. When they start to play with toys in more complex ways (stacking, pulling them apart, putting them in and out of containers), they are more likely to use a dominant hand. Babies tend to be older (18 to 24 months) before handedness becomes more consistent. No matter what age your baby starts to prefer one hand over the other, there are a couple of things you should know. First, handedness is really a continuum, meaning that most babies can use both hands but they tend to use one hand more effectively than the other. Some people rely on the preferred hand for nearly everything, others can use both hands for most tasks. Handedness in adults and older children seems absolute only because of habits and more practice doing daily activities like eating and writing with one hand. Second, researchers have found that babies are less likely to show hand preference when they are learning new skills. That means that you might see your baby using one hand much more often than the other until he starts doing something new (like standing) and then he might use both hands equally until he masters the new skill.

Babies' Firsts: When Babies Begin to Stand


A few weeks ago, we asked our readers to share information about when their babies learned to stand (click here to go to the original post). Specifically, we asked:
  • How old was your baby when he or she first tried to pull up to stand? 
  • What did you baby use to pull up on (for example, furniture, toys, etc)
  • How long did it take for him or her to stand alone, without holding onto something?

Today, for part 2 of this Babies’ Firsts topic, we want to share what the research shows about how and
when babies learn to stand!

As we've mentioned many times, babies develop and master new skills at different ages. The children of our staff at the Human Lactation Center illustrate this fact perfectly! My oldest daughter, Olivia, didn't stand until about 11 months, but my younger daughter, Charlotte, first stood at 6 ½ months. Jen G’s daughter Lily stood at around 9 months and our newest edition, Karolina’s son David first pulled to stand at 7 months.  

Our experience with our children perfectly represents what has been shown in the developmental research! Studies show that 50 percent of babies can pull themselves up to standing with support at 8 months and 90 percent of babies can by 10 months old. 

When learning to stand, your baby will need to use his arms to hold himself up on something and may be standing wide legged on his tip toes until he gets into the swing of things. During this time your baby will begin to use less arm support and may begin to shift his weight from side to side. He will need to get used to moving and controlling his body in this new position.  Soon he will be able to rotate his body around and use one arm for grabbing objects. He will also be able to reach down from a standing position to grab items off the floor.

By 13 months 90 percent of babies will be able to stand without support but still need to practice staying balanced. They will begin cruising around, that is holding on to furniture and moving sideways. Very soon after cruising, babies will begin taking unassisted steps.  They may still fall often, but don’t worry, their brains are hardwired to keep practicing until they get it right!

When your baby starts showing interest in pulling up to stand, it is very important to make sure he practices in a safe environment. Pulling up on things that move easily could be dangerous, so we encourage you to get down on his level and look for unexpected dangers. For example, when Charlotte started to pull up, she crawled over to her sister’s dollhouse and, before I could get over to her, she had tried to pull up on it. The plastic dollhouse was not sturdy enough to hold her weight and it scooted across the floor while she fell forward. Luckily, it scooted quickly so she did not hit her face on the pointed roof, but she could have easily gotten hurt. Small furniture, laundry baskets, and anything with wheels should be kept out of reach until your baby gets better at standing on his own.  At 14.5 months old, 90 percent of babies can independently squat from standing and shortly after they will be able to stand up directly from the floor without having to pull themselves up on something.

Pulling up to stand is a big milestone! If your baby is just learning to stand, Congratulations! Soon he’ll be running around you’ll be trying to catch up!

Babies' Firsts: When babies learn to sit up


A few weeks ago, as part of our Babies’ Firsts series, we asked our readers to answer these questions:
  • How old was your baby when he or she was first able to sit up on his or her own?
  • How did playtime change once your baby could sit up? 

We’ve gotten several comments from readers, so first we’d like to thank everyone who responded. Each of their babies started sitting up on their own right around 6 months! Not surprisingly, playtime didn’t change much for these babies because they had been sitting up with help, but they were able to play more independently and were showing more interest in toys than they had in the past!

Today, we would like to share what developmental research says about the ages babies tend to learn to sit up. As always, remember that all babies are different and they develop at their own pace. We will provide ranges, but if your baby does not fall in the range, don’t be alarmed. If you are unsure about your baby’s developmental progress, talk to your pediatrician!

Sitting with Support
More than 90% of babies are able to sit up while being held (at the chest/waist) by a caregiver by about 1 month old. In the beginning, the neck muscles are not developed enough to keep the babies’ heads from bobbing around while held in the sitting position, but within the first few months, their necks get stronger and they are better able to control their heads while being held in a sitting position.

Sitting with Propped Arms or Arm Support
Before being able to sit fully upright on their own, many babies can sit while using their arms to support their weight. According to the research, 50% of babies can sit this way by 2.5 to 3 months of age and 90% can sit this way by 4.5 months. This type of sitting shows off babies’ flexibility because they often look like they are folded right in half when sitting this way! Between 4.5 and 6.5 months, their arms get stronger and they are able to sit up higher with their arms closer to their bodies.

Sitting without Arm Support
The age range for the ability to sit without any arm support is much wider. Between 4.5 and 6 months, babies usually begin sitting without their hands or arms on the ground, but as you can imagine, they aren’t able to sit fully upright right away and need to be closely watched to make sure they don’t fall and hurt themselves. As they gain strength, they are able to straighten up more easily, and by 8 months more than 90% can sit up well enough to be left alone in a sitting position.  

Sitting and Moving Around
Once a baby has mastered sitting independently, he or she won’t  sit still for long. Fifty percent of babies can twist and rotate around to reach for things by 7 months and 90% can do this by 8.5 months.  Between 8 and 12 months, they start moving from sitting to lying on their tummies (50% around 8 months and 90% around 12 months), which is an important step to prepare for crawling!

Safety is key!
So, no matter when your baby starts sitting up independently, the most important thing is to keep them safe.  Even when they have been sitting for a while and seem to have mastered the skill, be cautious when sitting them down. Never leave your baby alone on a couch, chair, or bed and keep the floor around your baby clear when he’s playing.

Babies' Firsts: Sitting Up


Last year, we started a series of 2-part posts we called “Babies’ Firsts.” In the first part, we ask our readers to answer a few questions about the first time their babies did something exciting. Then, in the second part, we explained when and how babies tend to achieve the highlighted milestone.

So far, we've covered smiling, crawling, and rolling over, but it’s been quite a while since we've posted a new topic.

Today, we’d like to continue the series by asking you these questions:

  • How old was your baby when he or she was first able to sit up on his or her own?
  • How did playtime change once your baby could sit up? 

Send us a comment with your answers and watch for part 2, where we’ll share more information about how babies learn to sit up!

Babies' Firsts: The Science Behind Rolling Over

A few weeks ago, as part of our Babies’ Firsts series, we had the following questions for our readers:
  1. How old was your baby when he or she rolled over for the first time?
  2.  Did your baby roll from back-to-tummy or tummy-to-back first and how long did it take before he or she could roll both ways?
  3. What kind of adjustments or modifications did you have to make in your baby's environment to accommodate his or her new skill?
First, we’d like to thank everyone who commented! Your stories show that every baby is different and that even siblings who grow up in the same environment achieve milestones, like rolling over, at their own pace. Today, I’ll share the story about when my youngest daughter, Charlotte, learned to roll over and then explain what research shows about how and when babies tend to develop this important skill.

Charlotte’s Story
Charlotte is 7 months old now and she’s been rolling over for 3 ½ months. She first rolled from her back to her tummy while we were playing together on the floor. Although we had been having “tummy time” a few times each day, she never seemed to like it, so when she first rolled over, she promptly started crying. I helped her roll back onto her back, but within just a few minutes she was back on her tummy again. It went on like this for a few weeks until she learned to roll from her tummy to her back.

We had to make quite a few changes when Charlotte started rolling over. We had to be much better about keeping the floor clean and making sure that her big sister, Olivia, picked up her toys. We also had to start keeping all the dog toys out of reach and I bought a foam play mat to make our hard floor a little softer for her. All of the effort came in handy, because before long she was army crawling all over the house (but that story is for another post!).

Rolling Over Research
Everyone knows that there are 2 ways babies must learn to roll, from back-to-tummy and tummy-to-back, but many people (including me, until today) may not know that within each of these rolling methods there are 2 types, with and without rotation. Here is information about each type:

Prone to supine (tummy-to-back)
  • Without rotation – Rolling from tummy-to-back without rotation means that the shoulder and pelvis are aligned, body is extended, and the movement starts from the head.  It can start as early as 1 month of age, but only about 10% of babies can roll this way by 3 months; 50% and 90% achieve it by 6 and 8 ½ months, respectively.    
  • With rotation – Rolling from back-to-tummy with rotation is characterized by a shoulder and pelvis that are not aligned, movement originating from the shoulder, pelvis, or head, and rotation in the body.  Because the rotation is a more complicated movement, this type of rolling typically starts around 4 months with 50% achieving it by 7 months and 90% by about 9 months.
Supine to prone (back-to-tummy)
  • Without rotation – When a baby rolls from back-to-tummy without rotation, his head will be up, his body will be stretched and his shoulder will be in line with his pelvis. The movement will begin from the head, shoulder or hip, and his body will move as one unit. Fifty percent of babies can roll this way by about 5.5 months and 90% reach this milestone by 9 months.
  • With rotation – Rolling this way requires the baby to lift his head and stretch his body and the movement starts from the head, shoulder, or hip, but the shoulder and pelvis will not be aligned, the baby’s body will rotate, and the legs will move separately from the rest of the body. Just as with tummy-to-back, rolling with rotation is mastered a little later than rolling without; 50% achieve it by 7 months and 90% by 9 months.
So, the take-away message: The age at which babies master rolling over varies greatly! If you think about it, it makes sense given that rolling over requires the coordination and use of many muscle groups.  Regardless of the age of your baby, rolling over means that you have some baby-proofing to do! For more information, refer to Baby Proofing Part 1 (for birth to 6 months) and Part 2 (for 6-12 months).

Questions for our Readers: Rolling Over

Back in April, we started a new series where we ask our readers to share their experiences watching their babies achieve various milestones. In the first post, we asked for stories about one of the first (and, in my opinion, most exciting) major milestones, smiling!

For the second installment of our Babies’ Firsts series, we want to know about rolling over! Specifically, we’d like to know:

  1. How old was your baby when he or she rolled over for the first time?
  2. Did your baby roll from back-to-tummy or tummy-to-back first and how long did it take before he or she could roll both ways?
  3. What kind of adjustments or modifications did you have to make in your baby's environment to accommodate his or her new skill?
So, if you’d like to share what it was like when your baby started rolling over, please send us a comment! Keep in mind that all babies are different. We are not trying to encourage competition about whose baby rolled over earliest; we simply want to provide an opportunity for parents to share their experiences with each other. Next time, we’ll describe what the research shows about how and when babies start rolling over and share tips to help parents make sure that their newly mobile little one stays safe.

Answers to Our Latest Baby Milestone Quiz!

In our latest quiz, we asked several questions about babies' milestones. Here are the answers!

1. How old are babies when they first can coordinate sucking and swallowing?

a. Before birth
b. 1 day
c. 1 week
d. 1 month

Answer: a. Babies can coordinate sucking and swallowing by about 28 weeks gestation. Amazing!

2. How old are babies when the newborn sucking reflex is replaced by the ability to suck voluntarily?

a. Before birth
b. 4 days
c. 4 weeks
d. 4 months

Answer: d. I bet this one surprised you. Of course, this change doesn't happen all at once but occurs gradually. At the same time that babies are able to suck on things voluntarily, they are also gaining control over motor skills that allow them to bring things to their mouths. Around 4 months, babies add a new way to explore objects - by  mouthing and tasting them. Keep that in mind when you are babyproofing.
3. How old are children typically when they can first use 1000 words?
a. 12 months
b. 24 months
c. 36 months
d. 48 months

Answer c. For many parents, the explosion in the number of words that their children use is one of more exciting parts of their babies' development. We shared a series about language development in the Fall of 2009. Babies learn words that they hear each day. So keep this in mind, your baby will be very good at remembering the words that you use.

4. How old are babies when they can focus and coordinate vision in both eyes at the same time?

a. Before birth
b. 1 week
c. 7 weeks
d. 14 weeks

Answer. d. Vision develops very quickly in infants. Other systems can take months or years to get up to speed. If you pay close attention, you will see that your baby gets better and better at following objects with her eyes as she gets older.

5. How old are babies when they can coordinate both hands so they can hold objects that are too big for them to hold in one hand?

a. 4 to 5 months
b. 8 to 9 months
c. 11 to 12 months
d. 14 to 15 months

Answer c. Motor skills that require both hands are far more challenging than most of adults imagine. An earlier significant milestone occurs when babies can pass objects from one hand to the other. Older babies can start to manipulate large objects by using both hands to hold them. For many children, it is several years before they can consistently catch an object tossed to them. So don't worry if your older baby drops objects when you try to play catch. Your baby will still have fun trying!

Baby Proofing by Baby’s Stages Part 2: 6-12 months

Welcome back! Today’s post is part 2 in a series focused on using your baby’s developmental stages to help baby-proof his environment. Now let’s take a look at the older baby, age 6-12 months. Note: If your baby is just now moving into his crib, review part 1 of this blog for links to check crib safety.

6-7 months
Your baby may have mastered rolling as an efficient mode of transportation or he may be getting ready to crawl. Warning! If you haven’t already completely baby-proofed your home, now is the time. Your baby’s instinct will be to poke, hold, and taste anything and everything he comes across. Almost everything that is small enough to pick up can end up in your baby’s mouth. The 6-7 month old is also learning to have more control over his body movements. What does this mean for you? Your baby will be even more explorative because he has an innate drive to practice his newfound motor skills (rolling, crawling, etc.) almost constantly. Here are a few specific tips to keep him safe:
  • Remove any hanging toys from the crib when you notice your baby can reach up and touch them.
  • Put outlet covers on all outlets; even those hidden behind furniture. Little arms and fingers can find their way into the smallest of holes.
  • Lock cabinets; especially those that contain any poison or chemical that could be ingested.
  • If unable to lock cabinets, remove all poisons and chemical cleansers to a safer location; like the garage. This includes medications, alcohol and even vitamins.
  • Clear all objects off coffee tables, or other low furniture. Even magazines and newspapers can be a hazard. Babies will be able to tear pages and it will almost always end up in their mouths. This can be a choking hazard.
  • A good rule to follow: if an object can fit through a toilet paper roll, it is a choking hazard and can get stuck in your baby’s throat. These items should be placed in a locked drawer or up out of the reach of your child.
  • Keep pet food (if any) out of the reach of the baby. This might sound like a silly tip, but I can attest from experience that your baby will be drawn to your dog’s bowl of puppy chow. It’s amazing how quickly they can move towards the food and pop a few pieces in their mouths!

8-10 months
Many babies this age are beginning to pull up on furniture (or people) to get themselves from a sitting to a standing position. With this new ability comes a brand new perspective of his world! Soon he will be walking along furniture and exploring everything that is in his new line of vision. Baby proofing must now be taken to the next level.

  • As soon as your baby can get up on all fours he could use the crib bumper pad as a step to climb out. Remove it from the crib.
  • Coffee tables and other furniture that babies could pull themselves up on should be cleaned off completely. Babies can pull heavy objects over on themselves easily or put things they find lying about into their mouths.
  • Furniture that can be potentially pulled over onto baby should be secured to the wall (upright book case, TV, etc.)
  • Double check outlets and cords. Remember, pulling up brings baby to a new height!
  • Watch sharp corners on furniture or any sharp object that is just the right height for head bumping. There are soft, non-permanent corner covers available for corners of tables. Or move the offending piece of furniture elsewhere for a while.

12 months
Most babies are learning to take steps and some are walking pretty well by this time. Again, more mobility leads to more exploring! Babies become little scientists, exploring and testing the world around them. When it comes to walking and movement, 12-month-olds often have a one track mind. It is common for babies this age to focus all of their energy on perfecting their newfound skill, leaving little time for eating, sleeping, or getting their diapers changed.
Now that your baby is more mobile, you may want to consider the following tips in addition to those mentioned earlier in this post:

  • Keep the bathroom doors closed or purchase toilet locks
  • Make sure breakables are completely out of reach. Remember babies are stronger and more mobile now!
  • Do not leave sharp objects such as scissors, clippers, pens and pencils within your baby’s reach.

“Baby Talk” and the Adult Brain

By Taryn Barrette, RD

The following is a "guest post" from our ever-energetic Taryn Barrette. Though not yet a parent herself, Taryn is a registered dietitian (and proud cat-owner) on our staff who is rapidly becoming a baby behavior specialist.

I always laugh when I hear my boyfriend talk to babies. He’ll say things like “Hello, George. How are you doing today?” in his most grown-up, monotone voice.

Then I chime in, without even thinking about the way my voice changes, with something closer to “Oh heh-woe wittle Georgie-Worgie!” I talk to our cat like that too. How is it that we can flawlessly switch from mature grown-up conversation to cooing, baby-talk gibberish without batting an eye? Well, it could be that our brains react differently in the presence of preverbal infants. In a new study, neurologists showed how mothers’ brains change in response to “baby talk.”

In an earlier post, we talked about how babies respond to “baby talk” and that the repetitive, articulate, higher-pitched “motherese” draws babies’ attention and helps with infant speech and emotional development during their first year of life. We talked about how younger infants make sounds to communicate, and then starting at around 6-10 months of age, babies begin to use signs along with sounds. Eventually, towards the end of the first year, babies start to use words. So we know that “baby talk” is vital for infant development, but how is it beneficial for parents and how does it help parents’ relationships with babies?

In a study conducted in Tokyo, Japan, researchers investigated differences between Infant-Directed Speech (IDS - aka “baby talk”) and Adult-Directed Speech (ADS - aka the monotonous voice my boyfriend uses with baby George). IDS shares similar characteristics with emotional speech, which is used when adults communicate emotions to other adults. Think of cooing, “I love you” to your significant other or using a higher-pitched, animated “Congratulations!” when your sister got promoted. Personality traits (i.e. extroverted vs. introverted) and gender can both affect the way and amount that adults use emotional speech; therefore, these differences may affect how adults utilize “baby talk” with their infants as well!

The researchers used voice recordings of 256 words that were either spoken in IDS or ADS. Study participants were first time moms and dads of preverbal infants, mothers of toddlers and mothers of school-aged children or adults without any children. The participants’ brain activity was measured while they listened to the voice recordings.

The researchers found that the mothers of preverbal babies were the only group who showed activity in the language center of the brain when exposed to “baby talk.” So, moms with preverbal infants who were speaking “motherese” were more likely to be processing “baby talk” as a form of language than mothers whose children were older or fathers of those same children. That could explain why my boyfriend has no interest in “baby-talk.”

The scientists also found that extroverted mothers (women who are naturally more outgoing) were more likely to use “baby talk” with their infants. The more a mother uses IDS, the more her language centers of the brain are activated and the better she gets at using and processing “baby talk.” So, moms: keep talking to your babies! Even if other people give you a hard time, you are helping to improve your baby’s speech and at the same time molding your own brain to become more in tune with baby talk.

Update – Graduation from Developmental Follow-up

Last year, I wrote a blog post about my family’s experience at developmental follow-up appointments for our daughter who was born 15 weeks early. For those of you who are new to this site, our daughter, Olivia, was born at 25 weeks gestation and weighed only 1 lb 15 oz. Even though she came so early and was so tiny, she is a remarkably healthy and happy child. If you would like to know more about our experience, you can read all about it in a 3 part series posted last year titled “When Motherhood Doesn’t Go According to Plan.” Part 1 covers what it was like to deliver our baby early, part 2 describes our life while Olivia was in the hospital, and part 3 provides tips for coping with a premature baby’s hospitalization.

Just as a reminder, when babies are born prematurely, they are at risk for delays in their physical, cognitive and emotional development. In an effort to detect and address any delays as early as possible, infants who were born prematurely often require special appointments with a team of developmental specialists. During these appointments, the specialists use a variety of tests and measurements to evaluate how the baby is maturing.

Olivia, now 27 months old, has visited the developmental clinic 3 times, at 10, 18 and 26 months. Like I explained in the original post, our family really looked forward to these appointments. We enjoyed watching Olivia complete the evaluations and were anxious to learn about ways we could help her development progress. At the first appointment, we were pleasantly surprised to learn that she was already ‘catching up’ and we used every tool the developmental team gave us to help her along. At the second appointment, we were even more surprised when they told us how far she’d come.

The 3rd appointment progressed much like the first 2. The appointment started with the Bayley Scales of Infant Development testing, which is used to evaluate cognitive, language, and motor development. For Olivia this test was more like a game where she got to put puzzles together, stack blocks, and look at picture books. Next a nurse practitioner measured Olivia’s growth and reflexes. The growth measurements are a little more extensive than those performed during normal pediatrician visits, but still only took about 10 minutes to complete. Finally, we met with a social worker to discuss any concerns we had and to get information about additional resources available to our family.

During our visit with the social worker, we were surprised once again! Originally, we were told to expect to attend at least 2 appointments per year for 3 years, but that the schedule could change based on our daughter’s needs. Because Olivia had tested so well, she was graduating from the program and wouldn’t have to attend any more follow-up appointments! She even received a graduation certificate with 3 pictures of her, 1 from each appointment.

Even though she has graduated from the program, Olivia is still at risk for some learning difficulties, so we will continue to watch her closely. The social worker gave us some information about services in our area in case any concerns arise. For example, once she turns 3 years old, Olivia will be eligible for any services offered by our local school district.

Overall, our experience with the developmental follow-up clinic was very positive. Even though we were nervous before our first appointment, we learned a lot at each appointment that we used to help our daughter reach her full potential. If you have a story to share about your experience with developmental follow-up of a premature infant, we’d love to hear from you.

Babies Development in the Second Year: 19-24 Months

Most parents have heard about the “terrible twos” reportedly filled with wild mood swings, tantrums, and defiance. For those of you with children closing in on their second birthdays, you may wonder when, and if, your sweet toddlers will turn to the “dark side.” In our last 2 posts, we described development that typically happens in infants between 12 and 18 months. Today, we’ll wrap up the series by focusing on changes that occur in most children between 19 to 24 months. A better understanding of development during these important months may help parents cope with the highs and lows of toddler parenting.

Cognitive Development – Planning, Perseverance, and Pretending

Between 18 months and 2 years, children’s ability to anticipate and solve problems expands. You can see this happening in your own child when she suddenly hesitates before she starts an action, like trying to put on her own socks. She'll look thoughtfully at those socks as she concentrates on each step in her plan. With each attempt, she may pause again, puzzling through solutions to each barrier along the way. Play becomes more creative and complex. Many toddlers are able to play noticeably longer by themselves. They love to pretend and will invite you to join them. With improved memory and the ability to anticipate, perseverance begins to emerge. No more “out of sight, out of mind” for loud toys or dangerous objects because 2-year-olds can remember what they wanted minutes, hours, days, even weeks after you've said no. Meanwhile, toddlers' use of language blossoms. Words turn into short sentences structured loosely on their parents’ language.

Toddlers imitate everyone and everything that interests them (especially older siblings) as if they were walking video recorders. Most will believe that they can doing anything they see others do, including climbing, jumping, and swimming. Be extra vigilant around pools! I speak from experience. Unfortunately, toddlers' abilities often do not match their ambitions and many end up in tears when they aren't able to accomplish their goals. Routines can be a source of comfort for busy 2-year-olds and many love the closeness and relaxation that comes with cuddling with you to read a favorite book. Just be prepared to read that favorite book over and over again.

Social Development – A Sense of Self

As children approach their second birthdays, they become increasingly self-aware. They passionately embrace their independence from their parents...to a point. They simultaneously wish to be independent and completely protected and cared for. Emotions like pride and embarrassment become evident as toddlers celebrate their successes and struggle to cope with the inevitable accidents and mistakes. With all the distractions in their world, most toddlers find it difficult to concentrate on any one thing for very long. Listening to your instructions becomes a real challenge. When you need your child to listen carefully to what you have to say, it may help to get down to her level using your face and body to block out distractions as you talk. With her new found problem solving abilities, your child will try to discover how to get her way through experimentation and perseverance. Many parents believe that 2-year-olds are manipulative but toddlers are a still a long way off from a sense of right and wrong. Toddlers who point and cry in the store to get their favorite candy are experimenting to learn how best to get what they want. Keep in mind that toddlers will remember and repeat actions that work. Toddlers feel all of their emotions with passionate intensity and, without the developmental changes that come along in the next couple of years to help them control those emotions, they lose control fairly easily.

Physical Development – A Whirlwind of Activity

At 2, many children are more active than they will be at any other time in their lives. Between 2 and 3 years of age, they learn to walk steadily in all directions, to climb stairs, to run faster, and to kick a ball. Most 2-year-olds still fall a great deal, especially when chasing older siblings. Two year olds are whirlwinds of activity because they are interested in nearly everything and have limited control over their emotions and actions. All of your stamina will be needed to keep your own little whirlwind safe!

We hope that you’ve found this short series helpful even if 2 years of age is a long way off for your baby. Coming up soon, we’ll have a post specifically about tantrums.

Babies’ Development in the Second Year: 16-18 Months

In our last post, we talked about how babies change and grow from 12 to 15 months. Today, we continue our series on babies' development in the second year by focusing on 16 to 18 months. As we mentioned last time, most parents are thrilled (and challenged) by the speed with which their younger toddlers change and develop new skills but, as the old saying goes, “you ain’t seen nothin’ yet.”

Cognitive Development – Problem Solving in an Expanding World

One of the most remarkable things about toddlers is their ability to set their own pace, no matter how busy their parents are, as they focus on investigating their expanding world. As they approach 18 months, babies' insatiable curiosity drives them to experiment and observe according to their own schedule. As their brains grow, toddlers are better able to remember past experiences and events. They begin to mimic what they've seen others do several hours or even days earlier. For the first time, they are able generalize past "experiments," realizing that toys at grandma’s house will work the same way as toys at home. Babies’ vocabularies also expand rapidly (they add about 3 new words per day) and babies start to put words together into basic sentences.

Social Development – Emotion Explosion

As babies’ thinking becomes more complex, so do their emotions. Their need to be near family and friends remains strong, as does babies' fear of separation. While toddlers want to show their independence and do everything themselves, they are easily frustrated by their limited physical skills. Playing with older children, who are better able to run and climb, can be a source of both great pleasure and consternation for toddlers. Emotions become more intense but also more focused and it becomes easier for parents to identify the source of their children's sudden outbursts. Naps, snacks, and routines can go a long way in limiting toddler meltdowns. It is common for babies of this age to seem to prefer the company of one parent versus the other for several hours or days at a time. Mom or dad may feel left out but no need to worry, babies will happily reach for both parents as their needs and interests change.

Physical Development – Picking Up Speed

For many children, the days between 15 and 18 months are spent perfecting their ability to walk upright. Standing, walking, balancing, crouching, and climbing become obsessions to be practiced all day (and sometimes all night!). As they become steadier on their feet, babies will walk less on their toes and use a narrower stance. After that, running is only a heartbeat away, often before parents are prepared. If you thought your toddler was busy before, watch out! The pace is really going to pick up. Babies' fine motor and problem solving skills continue to improve and they become highly skilled at getting into closed containers and cupboards. Baby proofing needs to be ramped up yet again.

By 18 months, babies are showing off their individuality even as they struggle (sometimes dramatically) to understand and fit into their parents’ world. The tiny baby once so easily held in his parents’ arms has grown into a child who will twist and squirm away as he learns to stand on his own two feet.

Babies' Development in the Second Year: 12 to 15 Months

Time flies! Our baby behavior blog is almost a year old! From our recent poll, we learned that many of our readers were interested in hearing more information about older babies.

Today we begin a new series on babies' development from 12 to 24 months. If your baby is still young or you are waiting for your baby, we encourage you to read our earlier posts on infant development starting with the information on newborns. You'll be able to read all of the parts of that series by following the links at the end of each post.

Cognitive Development - Devoted to Discovery

For many parents, the rapid changes in their babies' thinking and ability to communicate in the second year become a source of both pride and frustration. Babies' experiments to discover how the world works expand and become more creative and complex. While a few months earlier, babies may have been content to shake objects put into their hands, young toddlers want to twist, turn, open, and bounce things over and over again. Toddler's "devotion to discovery" is key to their growth and development but it also requires careful supervision as some of their experimentation (like tasting whatever they find under the sink) can put them in harm's way. At the same time, babies' memories improve, allowing them to recall and repeat groups of related behaviors. It is not uncommon to find young toddlers trying to imitate their parents' or their siblings activities. Babies will expand their early efforts at words and start to point at objects so that their parents can name them.

Social Development - Strangers and Security

As babies become more mobile and able to move quickly away from their parents', their fear of separation and strangers grows. Allowing a little more time for introductions to new people (or people they don't see often) will go a long way in helping your baby stay calm. Many babies between 12 and 15 months will want to do more things for themselves which can be very stressful for parents who don't have time to wait 20 minutes for their babies to pull on their socks. Babies' desires for activity, movement, and independence get out of sync with their abilities, leading to frustration, anger, and the occasional meltdown. Babies this age also develop persistence in their desires making it harder to distract them away from the things they want.

Physical Development - Moving On Up

Most babies learn to walk between 12 and 15 months of age. They will also experiment with getting up and down from different positions (like from their hands and knees or squatting). Many babies also find they like to climb. Be ready! As their bigger muscles get stronger and more coordinated, fine motor skills also improve. Babies get better at grasping very small objects with their fingers and learn they can use both hands to hold onto to larger things. These new skills allow babies to explore objects in new ways. Now, they can pinch, pull, squeeze, and throw toys (or valuables) rather than just touch them. Unfortunately, babies' increasing dexterity can be a source of danger as they develop the ability to pull caps off bottles and open cabinets. Baby proofing becomes increasingly more complicated and necessary. Remember, once babies start an action (like reaching for a hot pan), it can be very hard for them to stop. It isn't a matter of discipline, their bodies just take awhile to respond to their brains.

It is no wonder that parents of toddlers can become overwhelmed with the amount of energy and vigilance necessary to keep their babies happy and safe. At the same time, parents are astonished by the number of new skills their babies acquire with each passing day.

Entertaining Your Baby Without Breaking the Bank

Each one of us here at the Human Lactation Center knows what it is like to be a new mom. In fact, 3 of us have kids under 4 years old! We know how it feels to never have a minute to ourselves and to struggle to get everything done. In our last post, we talked about the time and expense involved in buying products designed to entertain babies and we shared some of the reasons why baby videos are not good babysitters. Now, it's time to share some ideas about ways to keep your baby happy while you're trying to get things done without buying any fancy baby "gear."

  • As we mentioned in a previous post, young babies get exercise just by being able to move their arms and legs. If you need a few minutes to make a phone call, let your baby spend some time laying on her back in her crib, even if she is awake. If you will be close by, you might want to put her down on her tummy on a mat or blanket on the floor (in a safe place where you can see her) so she has a chance to move around. You may think this sounds boring, but babies are easily entertained by simple things, even watching their own feet. If you want to make sure she isn't bored, you can put on some music.

  • While cooking dinner, place a few unbreakable bowls, spoons and utensils on the floor for your baby to play with. Or, designate a few drawers that are out of baby's reach in the kitchen where you can store safe playthings like kitchen towels, small pots and pans, or plastic/wooden bowls to keep your baby busy. Rotate these items by taking them out of the drawers and putting them back when your baby gets tired of them. Remember to vary their size, color, and shape to keep baby's interest.

  • Need a few moments in the bathroom? Pull a playpen into the bathroom or up to the open doorway. Fill it with a few fun, safe toys & books, place baby in, and you might get about 5 uninterrupted minutes to take a quick shower. Singing a few songs to your baby while you shower may entertain her enough to buy you 5 more minutes!

  • Wear your baby in a sling or front pack. You'll be surprised what you can get accomplished with both of your hands free! Also, your baby will love being close to you and watching (and learning from) everything you do. You can straighten up the house, throw together a quick lunch (just don't use the stove), gather laundry, or do other chores.

  • Share the fun! Ask your partner, friend, or family member to play simple games with your baby so that you can take a break. I know this seems obvious, but sometimes parents forget to ask for help! If you have older children, they can be wonderful "entertainers" for your baby. Just be sure to supervise their play in case they get a little too enthusiastic!

  • Plan 1 or 2 chores around baby's nap time. Don't go overboard on this one. Don't try to get everything done while baby sleeps. Your rest is more important than most household chores.

  • If you are trying to get a break from a crying baby, remember it is best to use repetitive sounds (like singing) and movements (like rocking) to calm your baby. It may be tempting to use a video to quiet your baby. Your baby may even stop crying for a few moments to stare at the screen, but all the noises and flashing images on the video won't calm your baby, so the quiet won't last long.

  • Some babies need "entertaining" because they are getting either too little or too much stimulation. If your baby spends too much time in the car seat or looking at the same wall, don't be surprised if she demands some attention. Watch for her cues that she is ready to play and rather than fighting it, give in and play for a little while. Babies get tired easily and you'll get your break. Alternatively, make sure that your baby doesn't get too much stimulation (for example, at dinner time) so that you end up having to spend an hour calming her down. A little goes a long way when it comes to playtime with your baby.

Now it's your turn. Tell us how you keep your baby entertained without spending money or using videos.

Next time: We'll share some ideas about dealing with overly enthusiastic friends and family.

Monitoring Development in Babies Born Prematurely - My Experience during Developmental Follow-up Appointments

Bringing home a baby who was born prematurely is a big milestone! In a previous post, I described how it felt to bring my daughter home almost 2 ½ months after she was born. It was exciting that she was strong enough to come home, but it was a little scary too. Even though she was finally home, our experience was still different than it would have been if she had been born at term. We were careful about taking her out in public and about having visitors at the house, so that she wouldn’t be exposed to germs and illnesses. In the first month, we visited the pediatrician weekly, then monthly for the next year. Now that she is older, we visit the pediatrician on the typical schedule, once every few months.

In addition to her normal pediatrician, we have appointments with a special medical team who evaluate her development. Because babies who are born early develop differently than most babies, it is important to monitor their progress and identify any issues early. Where families receive their developmental follow-up depends on a number of factors, including but not limited to type of insurance, location, and the infant’s risk level. One way is through an Early Intervention Program (EIP) which is a federal- and state-funded program for infants who are at risk of developmental delay. We had our appointments at a follow-up clinic connected with the hospital where Olivia was born. The hospital should provide information about who will be conducting the follow-up visits before your baby is discharged.

The number of appointments needed varies based on degree of prematurity, health status, and developmental progress. During the appointment, evaluations will be conducted by a number of different specialists. The development team typically consists of developmental pediatricians, nurse practitioners, physical therapists, occupational therapists, clinical psychologists, social workers and ophthalmologists.

We had our first developmental follow-up appointment when Olivia’s chronological age was 10 months and her corrected age was 6 months. Chronological age is the age from the day the baby was born. Corrected or adjusted age is the age of the baby based on the due date. For premature babies, both numbers are important. You need both numbers to get a clearer picture of where your baby should be developmentally. For example, although Olivia was 10 months old, she had just started sitting up, which is something babies usually do around 6 months of age.

I remember being really nervous before our first appointment because I didn’t know what to expect. It turns out I had nothing to worry about and that I actually enjoyed finding out how Olivia was progressing. Here is an overview of what happened during our first appointment.

First we met with a Pediatric Nurse Practitioner, who took Olivia’s measurements (weight, length, and head circumference), evaluated her muscle development and reflexes, and discussed her health history with us. The measurements were taken using very precise methods. Muscle development is examined because premature infants’ muscles develop differently than they would have in utero. For example, the muscles required to have a straight, stretched out body develop early in pregnancy, when there is plenty of room in the womb. As babies get bigger, the amount of space in the womb decreases, forcing them to curl into what is commonly called the fetal position. Babies who are born very early have to develop the muscles needed to curl up after they are born and the difference between developing in the womb and in a crib can affect how they learn to sit, crawl, and walk. It is very common for premature babies to have tight muscles and joints. Olivia’s ankles were especially tight, so we were given exercises to help them loosen up and make it easier for her to walk when she was ready.

Next, we met with a physical therapist, who conducted a developmental evaluation. The physical therapist used the Bayley Scales of Infant Development. The assessment evaluates cognitive development, receptive language, expressive language, fine motor development, and gross motor development. During the assessment, the physical therapist uses different toys to test the baby’s abilities and observes how the baby interacts with both her parents and with the world around her.

The last person we met was the social worker. She asked us questions about our support system (family, friends, etc), our work, and our life at home. The goal of the social worker is to determine how your family is coping with the new child and to address any needs you may have.

After the appointment, the medical specialists developed a report about Olivia’s developmental status. Copies of the report were sent to her pediatrician and to us. Summaries of the team’s observations were provided along with the scores from the developmental evaluation (based on both chronological age and corrected age). The final section of the report described the team’s recommendations and referrals.

So far, Olivia has visited the follow-up clinic twice, at 10 months and 18 months, and she is scheduled to go again at 26 months. Our second appointment was much like the first, just with different tests. Even though I was nervous before our first appointment, now that we’ve been through it, I am grateful for the opportunity to see how Olivia’s development compares to that of children born at term. It has also relieved some of our stress to know that she will get the help she needs if she encounters any difficulties.

12 months: Celebration and Independence, Frustration and Experimentation

By Jennifer Banuelos

Time flies when you are having fun, especially when you're sleep deprived! It probably seems like just yesterday that you brought your tiny baby home, but a whole year has gone by. While you are busy baking a birthday cake and wrapping presents, your 12-month-old is busy too! Here is a little of what you can expect from your toddler.

Social and Cognitive Development
While celebrating your baby's first birthday might make you feel sentimental, your baby is probably feeling confused. The need for independence intensifies at this age, but even though your baby wants to do things on his own, his ambitions are often far beyond his abilities. While his body is telling him to try new things, his brain is telling him to stick to what (and who) he knows best. Your baby's continued separation anxiety, can be very frustrating. Although you may be able to take some deep breaths to relieve the frustration, your baby's frustration can quickly mount into a tantrum. The key to handling these confusing times is patience, and since your baby is not yet capable of being patient, it is the perfect time for you to show her how it's done! When you notice your baby becoming frustrated, take a few deep breaths and assess the situation. Does she want some help, or is she determined to do something on her own? Either way, you will be more likely to best support her if you identify what she needs. Don't get me wrong, both of you will still get frustrated at times, but staying calm and showing your baby that you understand her frustration will help her feel safe and supported.I realize that it may seem like life with a 12-month-old is all about inner struggles and tantrums, but there's so much more! As babies transition into toddlers, they begin to see things from a new perspective, literally and figuratively. They become little scientists, exploring and testing the world around them. I remember giving my daughter a new toy in the car one day. It was an orange block with different textures on each side. She spent the entire trip turning it around, carefully inspecting each of the sides. I was amazed that she was entertained for so long by this block, which, in my opinion, was a pretty boring toy. For the next 2 weeks, she inspected that block every time we got in the car. Then, she discovered that it could be dropped. Even though it can be annoying to parents, dropping things is just another way babies test the world around them. Don't worry, the novelty wears off eventually! It is important to note that at this age, babies' memories are improving. If your baby does something that makes you laugh today, there's a good chance she'll do it again tomorrow, even if it is something that you don't want her to do again (like rubbing beans in her hair). Keep that in mind when you react to some of your baby's new behaviors. I should note that I am extremely bad at hiding my amusement with my own child.

Physical
When it comes to moving, 12-month-olds often have a one track mind. It is common for babies this age to focus all of their energy on moving around (whether they are walking or crawling), leaving little time for eating, sleeping, or getting a diaper changed. I had Olivia in the office one day, right before her first birthday. She was tired, so I laid a little blanket on the floor and rocked her to sleep. She fell asleep quickly (which was unusual). As soon as I placed her on the blanket, she sprung up into a sitting position. At first I was frustrated, but Jane was sitting next to me and she laughed. She reminded me that Olivia's motor drives were in full force! Within just a few days, Olivia pulled up on the couch for the first time. Although babies' sleep can be interrupted by the need to move, 80% of 12-month-olds sleep through the night (at least 6 straight hours.

We hope that you've found our posts on developmental stages useful. Remember, we've shared the research about what many babies do at each stage, but every baby is unique and they all grow and develop on their own schedule, not ours!

Next Time: We'll share a few more stories about our own experiences when our children were babies.

8-10 months: Learning to stand; the view from the top is very exciting!

We’ve mentioned many times that “every baby is different,” and it is probably more apparent between 8-10 months than at any other age! One baby may skip crawling altogether and go straight to standing or walking, while another may be perfectly content not to try to stand on her own for a few more weeks. Either way, change is in the air as babies work hard to achieve developmental milestones, and just as parents think they’ve got a nice routine worked out, sleeping and feeding patterns become disrupted once again. Yes, it’s frustrating, but when your baby is focused on achieving each exciting step, fatigue and hunger just aren’t the priority!

Social Development

By 10 months stranger anxiety is in full force. Continue to let baby take her own time getting to know new people or familiar people that she hasn’t seen for awhile. Separations may also become more difficult. As babies get more independent, they actually become more dependent on you as a safe haven. Prepare her when you leave by saying goodbye and reminding her that you will come back. Frustration becomes more intense and frequent at this age. I can remember my daughter rocking on her hands and knees crying out of frustration at not being able to get her hands and knees to move forward in coordination. It was almost comical, except for the times she awoke at 2am to practice in her crib!

Physical Development

As mentioned above, babies may wake to practice each new motor task during the night. As each new task is achieved, sleep will return to normal. Keep in mind that learning to stand brings a whole new perspective to baby’s view of the world and a whole new height for parents to baby proof (forget about hiding untouchables on top of tables or furniture now!) After babies learn to sit without any support, their next goal is crawling, followed by standing and walking. Soon they will pull up on furniture to stand and cruise along the couch. Some may even let go of the couch and take a brave step away.

Babies preoccupied by motor drives also prefer not to waste their precious learning time eating. Breastfeeding mothers may take this as a sign that it’s time to wean, but as babies become more independent, it’s important for them to have a safe place to come to between adventures, and what better place than their mothers’ arms during a feeding. Feedings can become quite the challenge when babies become mobile! Whenever possible, let him finger feed himself (with development of the “pincer grasp” baby can now pick up small objects with his thumb and forefinger.) Don’t be alarmed by messy feedings as babies practice this new skill and explore their food. That’s how they learn!

Cognitive Development

All of this new independence might make some parents start to think about discipline and wonder what is appropriate for a baby this age. I knew my daughter was ready for some limit setting when she crawled toward our dog, tried to touch his food bowl, and then quickly looked back at me with big eyes and just a twinge of a smile. Yes, I had told her to stay away from the dog’s food bowl about a dozen times, and yes, it appeared she remembered that she was doing something I wouldn’t approve of. Really the best discipline at this age is diversion. So, as I said “Yuck! No dog food!” I swooped her up and redirected her attention to a fun toy in the other room. Really, she wasn’t testing her power over me; she was just sweetly asking me to set that boundary for her so that she felt safe. The important thing when setting limits is consistency, and almost like déjà vu, I relived that very episode (baby to dog bowl, baby looks at me for disapproval, I say “Yuck. No dog food!”and steal her away from the scene to divert her attention) many, many times over the coming weeks.

By this age, babies also become goal-directed in their behavior (see dog food example above!). They also enjoy repetitive games like peek-a-boo more than ever because their understanding of object permanence and person permanence (understanding that caregivers still exist after they are out of site) are strengthening. They are better able to remember object locations and even begin to anticipate events and may try to make them reoccur. They also look for their caregivers after they leave the room. Parents can practice peek-a-boo or hiding games to help babies develop trust that their parents always return.

As evidenced by my daughter’s dog food incident, by about 9-10 months, babies are learning how to assess danger by watching their parents’ facial expressions. They begin to search for “emotional cues” from their parents as to whether there is approval or disapproval of their actions. Babies this age also love to learn by imitating and because they have developed more memory, they can watch you play with a particular toy one way on Monday, and repeat that same type of play on Tuesday themselves.

Next time: 12 months: The independent toddler starts to walk around; the drive to master walking will keep her busy day and night!

Infant Development from 6 to 7 months: New Wonders, New Skills, and New Fears

By six months, babies have become more predictable and are sleeping longer stretches, making caring for them much easier for their beleaguered parents. With more control over their own bodies, 6-month-olds become eager to explore their worlds and practice their ever expanding motor skills, sometimes finding themselves frustrated and a little fussy. Despite the ups and downs, many parents find this age to be one of their favorites.

Social Development

Babies who are 6 to 7 months old are highly social and interactive with those they find familiar. They will squeal and smile, flirt and flail their arms and legs, hoping for a joyful response and approval from their parents. Sometimes the squeals will turn to shrieks if babies are not given the attention they crave. Now, before you start thinking that responding to your baby will spoil him, imagine how it would feel to suddenly realize that you have the power to communicate with those you love (like figuring out Skype for the first time). Wouldn’t you want to tell them how much you cared and how much you wanted to be with them? And wouldn’t you “turn up the volume” if you thought that they couldn’t hear you? That’s all that your baby is trying to do.

Interestingly, babies at this age also become wary of strangers, recognizing that some of the faces that they see are unfamiliar. While unfamiliar faces were of interest in the past, they now are a little unnerving. Around this time, you’ll want to take introductions a little slower, no more passing the baby from adult to adult as you did when she was younger. Let baby take her own time to get to know new people. If you are patient, you'll find that she is happy to accept new relationships that are not forced on her too quickly. By the second half of the first year, babies start to figure out that they want to stay closest to their parents and those they see each day. Separations that used to be easy are now a little rocky and may be filled with tears.

Cognitive Development

Along with their new found social skills, 6-month-olds become little scientists, experimenting with the world around them as much as possible. While it is controversial when “object permanence” emerges, many babies around this age will start to enjoy games where things apparently disappear then reappear. "Object permanence" refers to the understanding that objects that you can't see still exist. Very young babies will lose interest in things that are out of their sight and don't look for them. Older babies enjoy peek-a-boo and seeing objects that come out of hiding places, like an old-fashioned jack-in-the-box toy or a ball that rolls in one end of a tube and out the other. As they gain control over their arms and hands, babies explore objects with their fingers as well as their eyes and many will put everything they can into their mouths. Sucking on toys and tasting blankets become major pastimes. Obviously, care must be taken that only the right things end up getting investigated in this way. Building on earlier learning about “cause and effect,” 6- to 7-month-olds will start to vocalize in more consistent ways, hoping to get the same response. While using words is still to come, babies will babble using consonants and vowels, returning to sounds that seemed to get the desired response.

Physical Development

The rapid gains in motor skills over the last couple of months accelerate. As baby learns to sit for longer and longer periods without support, his hands become free for reaching and grasping toys in his reach, first with his whole hand and then with just his fingers. Moving forward becomes an important goal and babies will work hard to creep along on their bellies and eventually to pull themselves up on their hands and knees. Many babies find themselves crawling backward at first, often becoming a source of entertainment for older siblings. Practicing these new feats may be a 24-hour a day job and night waking may increase for a short time.

If you haven’t already completely baby-proofed, now is the time. Take it to a new level. Babies progress so quickly over the next few months, you should "proof" your house now as if your baby could stand and walk. It is vital that you make sure that baby can’t get hold of anything dangerous, because his instinct will be to poke, hold, and taste everything.

Next time: 8-10 months: Babies are learning to stand and may pull up on furniture; the view from the top is very exciting!

Infant Development 4-5 months: Distractions, Distractions!

By Jennifer Goldbronn

The 4- to 5-month-old baby is smiling and charming, attracting looks from passersby. His new game: purposely squealing or coughing just to get a reaction out of you. He is also conquering a myriad of new physical achievements, performing new feats almost on a daily basis. All of this excitement makes the average 4-month-old quite distracted. As we take a closer look at infant development in this age group, try to refrain from comparing your 4-month-old to your sister-in-law’s 4-month-old; every baby is unique as to when he will reach each developmental milestone!

Social Development
As your 4-month-old becomes more aware of her surroundings, she will become distracted by everyone (and everything) around her. This can make feeding rather challenging! I can remember trying to discreetly breastfeed my daughter in a restaurant when she suddenly craned her neck around to flirt with the waitress at the next table. Suddenly, I accidently flashed someone at the booth next to us. Embarrassing? Yes, but if I hadn’t known better at the time, I would have worried that she was rejecting my attempts to feed her. Luckily, I knew that she was only temporarily side-tracked. As she became able to focus at longer distances, exploring the world around her became more exciting than nursing. This didn’t last too long, but for a few weeks, we spent more of our time nursing in quiet rooms, free of distractions (and waitresses).

Cognitive Development
A baby’s sudden interest in the outside world is actually an important stage in his development. Let your baby explore and look around as much as possible. He has just discovered the law of cause (if I do this) and effect (that will happen). He will begin to use the same noises over and over in his attempts to get the same responses. He will love to play repetitive games and squeal with excitement whenever he finds he can predict your actions. Because he is so interested in his expanding world, you might find it easier to feed your baby in a quiet place, and keep baby’s sleep area free from distractions as well. Soon, baby will adjust to the extra stimulation and will focus back on Mom and the breast at feeding time.

Physical Development
Physical development is advancing at an amazing rate around 4-5 months. Babies are learning to sit with support and to use their hands to balance while sitting. They begin reaching and often are able to put objects in their mouths and transfer objects from one hand to the other. While counseling a mother of a baby who had just learned to reach for objects, I remember the mother exclaiming “Oh look! He’s reaching for his brother’s goldfish crackers! He must want some!” As I explained to her that her baby would practice reaching for ANY object, the baby demonstrated by quickly reaching for the board book I put in front of him.

Now is the time to expand tummy time! Tummy time is important for babies to develop strong back, arm and shoulder muscles for crawling. You can make this time more pleasant by getting on baby’s level to help engage his interest. Some babies this age might also roll over, but this happens at different ages for each child.

Growth Spurts
Four-month-olds often go through a growth spurt. Don’t be surprised if your baby wants to feed more often for a few days. A baby’s increased need for calories is important at this time for both physical and cognitive growth. If you are nursing, your body will automatically respond to these increased feedings by making more milk. Some breastfeeding mothers see this increased hunger or fussiness as a cue to start solid foods like cereal or to supplement with formula, but until a baby is 6-months old he needs nothing but his mother’s breast milk.

Sleep
For most families, there is a noticeable change in baby’s sleep around 4 months. Baby starts to fall asleep in quiet sleep and sleeps deeply for longer stretches. Many parents start to feel the fog of sleep deprivation lift a bit. However, off and on, all of the exciting things your baby is learning may disrupt his sleep. This is normal! Changes in routine, teething, illness, and overstimulation can increase night waking for a few days at a time throughout the first year. Be patient; this won’t last forever. You’ll get a LOT of advice about your baby’s sleep around this age. We find that most families find routines that work for them, eventually. Perhaps that’s a good topic for a future post.

Babies’ Development from 6 to 8 Weeks: Changes, Challenges, and Social Smiles

For most parents, getting through the first 6 weeks with a newborn is one of the most physically and emotionally challenging experiences of their lives. Time seems to almost stand still as a cloud of distracted half-awareness descends over day-to-day routines. Around six to eight weeks, things change, at first almost imperceptibly and then with lightning speed. After those grueling early months, parents begin to see a unique person emerge from the mass of needy newborn reflexes. Their tiny babies begin to become much more predictable, social, and a lot more fun!

Social Development

For most babies, social smiles appear around 6 to 8 weeks of age. These smiles are all the more welcome because babies’ crying also peaks around the same time. Some 6-week-old babies may cry for 2 hours a day, often in short spurts with one longer spurt in the late afternoon. For more about why this happens, read our prior posts about crying and persistent crying. Fortunately, as babies get closer to 2 months of age, their crying tapers off and parents have a better idea about what to do to calm them. When they aren’t crying, babies are working harder than ever to interact with the adults around them, smiling, imitating, and vocalizing, whenever they can. Remember, social activity is hard work for babies. Watch for disengagement cues and slow down or stop interactions whenever they show signs that they need a break. Remember that babies can’t be specific about what they might need the break from, so if it isn’t obvious, pay attention to what might be going on around you that might be bothering the baby. As the erratic behavior common in the first 2 months starts to fade, babies’ unique temperament and likes and dislikes begin to emerge. Some babies love noise, lights, and active play while others can handle only a little stimulation at one time. Some babies seem to be quick to calm, while others take more time to relax.

Cognitive Development

By six to eight weeks, babies show clear signs that they can predict what will happen during feeding, social, and naptime routines. They will move their legs and arms and coo excitedly when they anticipate food or fun and turn or arch away when they know something not so fun is about to happen (like a diaper change for those who don’t like them). Babies more obviously recognize their favorite people and are less interested in strangers. They’ll enjoy looking quietly at objects and listening to noises for longer periods as they try to learn more about them.

Physical Development

Newborn reflexes start to fade as babies begin to gain more control over their bodies. Many babies will have an easier time moving their heads from side to side, picking up their heads when placed on their tummies, and moving their hands towards their mouths. Nearly all babies of this age will flail their arms and legs at people and objects that they want to play with. Reaching and grasping is right around the corner! With so many possibilities for movement, it is very important to never leave babies unattended in places that are not perfectly safe. Never leave a young baby on an adult bed, couch, or high surface. You won’t believe how far they can move, long before they can roll or crawl.

Part of the wonder of being a new parent is to watch your baby’s unique personality emerge and develop. After the first 6 to 8 weeks, babies begin to change so quickly that you’ll find that there is something new to share everyday.
