This is a sleeper with a sewn-in hem. It's shaped like a long vest, allowing you to completely wrap your baby. Since it won't come undone like a blanket, you don't have to worry about your baby getting cold. The front zipper makes it easy to put on, take off, and change diapers. *Because the hem is sewn, the baby cannot walk while wearing it. This animal-patterned cotton sleeper comes in a box, making it perfect for gifts.
