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.
The decision to use cloth or disposable diapers is a controversial one, owing to issues ranging from convenience, health, cost, and their effect on the environment. Currently, disposable diapers are the most commonly used, with Pampers and Huggies being the most well-known brands in the industry. Plastic pants can be worn over diapers to avoid leaks.
