Hanna Andersson Baby Zip Sleeper in multicultural Christmas Print 🎅🏽 6-12M. Used condition shows crawling wear (in photos) Crafted in organic cotton, our baby sleepers are specially combed to leave only the longest fibers for extra softness all night, and the flatlock seams are smooth on baby's skin. The snug design zips quick at changing time, washes beautifully, and makes life as easy for newborns as it does for new walkers.
