paraphilic infantilismA sexual fetish in which the participant role-plays regression to an infant-like state by drinking from a baby bottle, sleeping in an oversized crib, playing in a playpen and wearing diapers. The activities have overtones that range from gentle and nurturing experiences—those who engage in banal infantilistic play are known as adult babies—to those with dark, sadomasochistic content. Not all adult babies are diaper fetishists, whose sexuoeroticism hinges on wearing diapers (covered in urine and faeces). Those who do are termed adult baby/diaper lovers (AB/DL).
