This well-fitting sleeper wraps babies like a big hug and keeps them warm thanks to its thicker mesh. With ribbed wrists and ankles, the sleeper leaves baby's hands and feet free to grab on for crawling, rolling and walking. The full-length front zipper makes it easy to put the sleeper on over sleepy little heads or take it off before starting a new day of adventures.
