Sleepea® 5-Second Baby Swaddle
We lost sleep over creating the best baby swaddle so parents don't have to!
Sleepea is the ultra-soft, simple-to-use swaddle that helps babies sleep longer and happier. Our patented 5-Second Swaddle design makes safely wrapping your lovebug as stress-free as can be!
Because Sleepea is made with soft organic cotton and breathable mesh panels, you can rest assured that your little one will not only sleep comfortably all night long (no matter the season), but they’ll snooze safely, too. After all, Sleepea was designed by renowned pediatrician Dr. Harvey Karp, the world’s leading swaddling expert.
Sleepea’s inner flaps give babies the womb-like embrace they love while keeping even mini escape artists securely wrapped and preventing the wild arm movements and nose whacks that can startle them awake. And, unlike most baby swaddles, Sleepea allows for safe arms-out swaddling, making it the perfect transitional swaddle for babies that are almost ready to wave bye-bye to their swaddling days.

For the first 6 months of life, babies should only sleep on the back. If your baby can roll, you should stop swaddling the arms. That’s because babies need to be able to push up in case they roll to the tummy and the face is pressing against the mattress. (Always consult your baby’s doctor for their advice.)
