Diaper changing sheet

diaper changing sheet is a flat, often disposable or washable, piece of fabric designed to be placed on a changing surface, like a changing table or a bed, during diaper changes. It typically has a waterproof backing to protect the underlying surface from moisture and mess. Unlike a changing mat, which is cushioned and portable, a changing sheet is usually thinner and meant to be used on a variety of surfaces for added convenience and protection.
