About SNOO:

SNOO is a responsive bassinet that boosts sleep for babies—and parents! Created by Dr. Harvey Karp (The 5 S’s, Happiest Baby on the Block), SNOO improves sleep by imitating the womb. It smartly responds to your baby's cries with white noise and jiggling motion-like going for a car ride-to help quickly calm the "fussies." It encourages healthier sleep patterns and even reduces your baby's need for sleep training.

The simple-to-use SNOO App allows parents to change levels remotely and personalize the experience.

And, it helps you meet your baby's needs for the first 6 months. Whenever you have to do chores, take a shower or get some sleep, SNOO is there-24/7-like your own personal helper.

Your baby will immediately be safer and will likely sleep better in just 1-2 days! (It may take 3-7 days for sleep to improve if SNOO is started later, between 6 weeks and 4 months.)

SNOO is FDA De Novo Authorized by the FDA and is now classified as a medical device. (De Novo means the product is a whole new and unique class of devices). SNOO is the first and only FDA De Novo Authorized Infant Sleep System (along with SNOO Sack, our patented swaddle that clips into SNOO) to keep sleeping babies positioned safely on the back. Babies who are placed on the back for sleep are at a lower risk of SIDS/SUID. For important safety information visit
