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 Sleep Sack was specially designed to be used in a SNOO Smart Sleeper. Each part helps babies sleep safer, longer, and happier. Every detail was purposely designed with baby safety and parent sanity in mind.
