As we’ve discussed infant sleep and parental fatigue, both in person at speaking engagements and with readers of this blog, we’ve gotten a lot of questions about the use of noise machines to help babies sleep better. While we understand the concept (white noise is repetitive stimulation, which we know calms babies), there are a few reasons we’ve been careful not to recommend use of these machines for babies. First, we know that babies, especially young babies, need to wake often (see Baby Behavior Basics Part 1) and second, we didn’t know much about the safety of these machines for use with babies. So, when a recently published study about the safety of infant sleep machines showed up in the news, it caught our eye.
