Pediatrician and child development specialist Dr. Harvey Karp and his wife and business partner, Nina Montée-Karp, founded Happiest Baby, Inc. in 2015 to develop science-based products, content, and services to enhance child well-being and solve everyday parenting challenges. The SNOO Smart Sleeper Bassinet helps boost a baby’s sleep and often can calm fussing by quickly responding with special white noise and jiggly rocking. It can even reduce the need for sleep training. SNOO’s unique 5-Second Swaddle is easy to use and keeps babies safely on their back when used as directed. Altogether, SNOO gives new parents the precious gift of rest and peace of mind.

Product Details

Newborns are immediately safer and usually start to sleep better in 1-2 days. Babies over 6 weeks are immediately safer, but may take 5-7 days to start sleeping better. Only use SNOO with the SNOO Sack, our special swaddle built for SNOO.

Care Instructions

For safety purposes, SNOO’s mesh is not removable. However, if you have a spill on the mesh we recommend spot cleaning with a damp cloth, warm water & baby-safe gentle cleansers.To clean between the mesh panels, at the head of SNOO there is a zipper you can wiggle a duster or vacuum nozzle to clean any dust or particles! As for cleaning SNOO’s foam mattress, we suggest spot cleaning with mild soap and warm water. Please make sure the foam mattress is completely air-dried before reusing. We highly recommend against putting the mattress in your washer and dryer, as doing so may damage or warp the foam.

Size & Fit

Use SNOO up to 6 months of age, or until your baby can get up on the hands and knees.
