Is SNOO safe for my baby?

In addition to meeting AAP guidelines (firm, flat surface), SNOO is FDA De Novo authorized for securing sleeping babies on their backs. Back-sleeping is the #1 safe sleep advice from public health authorities.

SNOO mimics the womb with gentle rocking and white noise that helps babies fall asleep and stay asleep. When SNOO detects crying, it automatically increases motion and shushing to calm fussing, often adding 1–2+ hours of sleep per night.

Does SNOO require a subscription or app to work?

You’ll get the calming benefits, safe sleep positioning, and basic controls without the Happiest Baby App. However, the App unlocks additional Premium Features. If you buy SNOO from Happiest Baby or Amazon, you’ll get a free 9-month subscription.

What makes SNOO different from other “smart cribs”?

SNOO is the only smart bed with a swaddle system that works with responsive motion and sound to help babies sleep safer and longer. It’s the only FDA De Novo authorized bassinet that keeps sleeping babies on their backs.

Does SNOO help babies learn healthy sleep habits?

By automatically soothing babies when they fuss, SNOO teaches them to settle with less parent help. SNOO also has features to ease the crib transition, like arms-out swaddling, and Weaning Mode, which gets babies used to sleeping without rocking.
