After tens of thousands of hours building, tweaking, and testing SNOO with hundreds of babies, SNOO Smart Sleeper is born! Soon after, our rental program launches, so even more families can enjoy sweet ZZZs.


Happiest Baby's Employee Benefit Program launches, giving new-parent employees at top companies a free SNOO...paid for by their employer!
Just as COVID began to overwhelm the healthcare system, hospitals around the world got an extra helping hand, thanks to the SNOO Hospital Program. Now SNOO is in 150+ hospitals, where research shows it saves nurses nearly 2 hours a shift!


The FDA grants SNOO De Novo authorization for its ability to keep sleeping babies safely positioned on their backs—making SNOO the first and only infant sleep system to receive this designation. See important safety information: happiestbaby.com/fda.
SNOO is the most awarded baby product in history, having racked up a staggering 50+ accolades. One of our proudest accomplishments? In 2023 Happiest Baby made TIME magazine’s list of 100 Most Influential Companies and SNOO Smart Sleeper made their list of 200 Best Inventions!
