SNOO Smart Sleeper

SNOO Smart Sleeper, from Happiest Baby, is a responsive bassinet that automatically soothes babies back to sleep. It imitates the sounds and motion of the womb with gentle rocking and white noise, responding to fussing within moments — often in under a minute — so babies sleep longer and parents can rest.

Overview

SNOO is built on Dr. Harvey Karp’s decades of pediatric research and is designed to add one to two hours of sleep per night. Its secure sleep sack keeps babies safely on their backs and prevents rolling, which made SNOO the first — and only — medical device to receive FDA De Novo authorization for its ability to keep sleeping babies safely positioned on their backs, reducing the risk associated with SIDS/SUID. SNOO also works as a gradual sleep trainer, weaning babies toward independent sleep by around six months with little need for cry-it-out. A companion mobile app logs and analyzes sleep, giving parents a clear view of how their baby’s nights improve over time.
