Save on baby gifts with Happiest Baby Cash Back from Hoopla! Happiest Baby was founded by Dr. Harvey Karp, the world-renown pediatrician and best-selling author of Happiest Baby / Happiest Toddler on the Block. Dr. Karp is recognized with discovering that infants are born with an innate Calming Reflex, which is triggered by 5 steps that imitate the womb—Swaddling, Side-stomach position, Shushing, Swinging and Sucking—the so-called 5 S’s. Millions of parents, doctors and hospitals worldwide have turned to the 5 S’s to effectively calm fussing. In 2016, Dr. Karp launched the SNOO Smart Sleeper, a responsive bassinet that solves the #1 parent complaint: exhaustion. SNOO “hears” crying and automatically responds with gradually stronger white noise and rocking motion to soothe fussing. Additionally, SNOO’s built-in swaddle prevents risky rolling, making it the only sleep solution that keeps your baby safely on the back—all naps/all night—as recommended by the American Academy of Pediatrics.
