I debated adding a baby sound machine to my registry. I had my mother telling me it wasn’t necessary; that I slept just fine without one (35 years ago, mind you.) But I also had first-time moms telling me it was the key to getting your baby to sleep at night. After some more conversations and a lot more research, I decided it was better to have a baby sound machine than not. Two years later I can honestly say it was a worthwhile addition to my baby registry.
Reading about the many benefits of baby sound machines ultimately swayed my decision. To start, they’ve been found to help babies fall — and stay — asleep. In fact, one study found that white noise may even help babies fall asleep faster.
“White noise machines can be extremely useful in assisting babies with falling as well as staying asleep,” says Miami-based pediatrician Gary Kramer, M.D., a pediatrician in private practice in Coral Gables, Florida.
Not to mention those types of sound can help baby transition from living inside the relatively noisy womb to a quiet nursery. This is especially helpful during the newborn phase when every bit of sleep matters not only for your baby, but also for you. As a new mom who is trying to recover from birth while adjusting to the new normal, you need all the rest you can (reasonably) get.
Now, you could easily use any device that plays white noise. Baby sound machines, however, often come with other features that are beneficial for baby or make life a little easier for parents (for instance, many double as a handy night light).
Read on to learn what features to look for in a baby sound machine, and which ones come highly recommended by parents (including myself and three What to Expect staff members).
How we chose the best baby sound machines
At first glance, it might be hard to tell what makes one baby sound machine apart from another. However, there are many different models on the market, all of which function a little differently from the next. In order to find out which white noise machines What to Expect parents like best for their nursery, we looked at results from the 2024 What to Expect Sleep Awards survey, where more than 1,150 parents voted on their favorite sound machine. We considered their favorites, looking at why they love their machine best and what sets it apart from others.
We also spoke to three parents on the What to Expect staff who have five children total between them and have each tested several baby sound machines.
To make sure that the machines on our list include the right features for helping babies fall asleep, we used expert advice from Dr. Kramer and the AAP. Note that the AAP recommends not exceeding 50 decibels (which is about the same level as an air conditioner running) on a sound machine in baby’s nursery.
