Happiest Baby

Our Story

Happiest Baby, Inc. was founded by pediatrician and child development specialist, Dr. Harvey Karp, MD, FAAP, with his wife and business partner, Nina Montée-Karp. The goal was to create a product for safely lulling babies to sleep and keeping babies on the back, the core safe sleep recomendation of US public health authorities. In 2016, Happiest Baby launched the SNOO Smart Sleeper – a bassinet which provides womb-like rhythmic sensations, responds with increased sound/motion to soothe fussing, and improves infant sleep safety by keeping them securely on the back.

Sleep Intervention

SNOO Smart Sleeper is a bassinet that uses SNOO Sleep Sack to secure babies to the bed’s platform and maintain sleeping babies in the supine position. (Babies placed in a supine position are at a lower risk of SIDS and SUID.)

Happiest Baby is working to expand access to the SNOO to all families who feel they would benefit.

FDA Indication for Use:

Keeping Babies Safe…All Night

SNOO is the first—and only—medical device to receive De Novo authorization from the U.S. Food and Drug Administration (FDA) for its ability to keep sleeping babies safely positioned on the back.

“The SNOO Smart Sleeper bassinet plus the SNOO Sleep Sack are jointly intended to facilitate a supine position during sleep.

Infants who are placed in a supine sleep position are at lower risk of SIDS/SUID.

The device is intended for home use by caregivers of infants from birth to 6 months of age, who are not yet able to roll over consistently.”
