This soft cotton sleep & play covers nap time to tummy time in one go - with a zip that makes changes quicker and built-in footies that stay on no matter what. The dreamy woodland animal graphics add some whimsy to every wiggly moment, whether you're halfway through a lullaby or chasing down a diaper. It’s cozy, it’s simple, and it doesn’t disappear in the laundry like teeny baby socks.
