The primary use of this band or binder is to keep baby's tummy warm and compressed. The belly band helps to calm and soothe your baby by applying "a little hug and a a lot of warmth" on the tummy. It also protects the belly to prevent stomach colds. The breathable band also protects the navel and umbilical cord area from bacteria or dirt that may come from clothing or diapers. Thus, it helps to reduce potential infection or irritation in the sensitive navel region.
