An infant bellyband, also known as an infant abdominal binder, is a tight, close-fitting garment that is worn around a baby's abdomen. It is designed to protect the baby's belly and genital area, and to prevent exposure to the cold or uncomfortable clothing surfaces. Infant bellybands are typically made of cotton, elastic fabric, or silk, and are soft and comfortable to wear. They also provide some level of warmth. In addition, an infant bellyband can help keep diapers in place and prevent leaks.
