A? nappy is a type of underwear that allows the wearer to defecate or urinate without the use of a toilet, by absorbing or containing waste products to prevent soiling of outer clothing or the external environment. When diapers become soiled, they require changing, generally by a second person such as a parent or caregiver. Failure to change a nappy on a sufficiently regular basis can result in skin problems around the area covered by the diaper.
nappys are made of cloth or synthetic disposable materials.
Disposable nappy/diapers contain absorbent chemicals and are thrown away after use. Plastic pants can be worn over diapers to avoid leaks, but with modern cloth diapers, this is no longer necessary.
