Happiest Baby, Inc. 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.
