Little Sleepies zippies are made of bamboo, which is great for sensitive skin and also fits a lot longer than the listed age due to the stretch! My baby was able to wear LS in newborn size until he was about 3 months old. This is a retired print and hard to find. Brand new with tags! Size: NEWBORN - Fold-over mittens - Fold-over foot cuffs on all sizes to instantly convert from footless romper to footed sleeper - Double zipper that makes those middle of the night diaper changes a breeze! - No snaps, buttons, or interior tags Corgi friendly, smoke free home. See my other listings for more baby items (doing a purge of everything my baby has outgrown!) Make an offer or bundle with other items from my closet!
