What is Diaper ?

Definition of diaper.

Nappy or diaper, a garment for incontinent infants amongst others .
A diaper (in North America) or nappy (in the United Kingdom, many Commonwealth countries and Ireland) is an absorbent garment worn by individuals who are incapable of controlling their bladder or bowel movements, or are unable or unwilling to use a toilet. The purpose of a diaper is to absorb moisture and contain mess so that the wearer can remain dry and comfortable after wetting or soiling themselves. When diapers become full and can no longer hold any more waste, they require changing; this process is often performed by a secondary person such as a parent or caregiver.
Failure to change a diaper on a regular enough basis can result in diaper rash.
