Paraphilic infantilism is a paraphilia characterized by the desire to wear diapers, due to reasons other than medical necessity, and/or be treated as an infant or toddler. It is also characterized by the carrying out of these desires on a regular basis. Within the community of such diaper wearers, one who engages only in the erotic or sexual aspect of diaper wearing without experiencing any accompanying regression fantasies is known as a diaper lover (or DL). An adult who only engages in the infantilistic play aspect is known as an adult baby (or AB). An adult who may experience both of these things is referred to as an AB/DL.
