When do you change an adult diaper?

An adult diaper shouldn't get too wet. Just like with baby diapers, keeping a wet adult diaper on for too long can result in diaper rash and bad odor. To prevent diaper rash, the diaper should be changed as soon as it becomes wet or soiled. People who wear diapers because of bed wetting should change their diapers when they awake. Some adults are able to change their own diapers. But many adults need help keeping themselves clean. If a person is invalid or mentally impaired, they'll need someone to change their diaper for them.
