A paraphilia involving a compulsive desire to wear a diaper (or if you're from the UK, a nappy) and perhaps behave like a baby. May also include a fascination with other related paraphernalia, such as baby powder or plastic pants. If you can't fit into baby diapers such as Pampers or huggies, you can make do with an adult diaper, perhaps Depends. See also Autonepiophilia or infantilism.
