A diaper cover is a garment that is designed to be worn over a baby's or young child's diaper. It serves as an additional layer of protection, helping to keep messes contained and preventing them from soiling clothing or bedding. Diaper covers come in various styles and designs, including onesies, pants, and jackets, and are made from materials such as cotton, fleece, or synthetic fabrics. They provide an extra layer of warmth for the child while also offering convenience to caregivers by making it easier to change diapers without having to remove clothes first.
