In March, the FDA granted approval to Happiest Baby’s Snoo bassinet, making it the first medical device ever approved to be marketed for infant sleep safety. Dr. Harvey Karp, a pediatrician and author of The Happiest Baby on the Block, created the Snoo in 2016 in order to reduce sudden infant death syndrome (SIDS), which kills thousands of infants a year. The “smart sleeper” bassinet keeps babies on their backs—the only sleeping position proven to reduce SIDS risk—and helps them sleep better with automated rocking and shushing. The Snoo costs almost $1,700, but the company recently made it more accessible with rentals for about $5 a day. The FDA approval also means it may soon be eligible for insurance coverage, the way breast pumps are.
