     By consenting to go along with Jerry's fetish, Barb set herself apart from the vast majority of women who live with adult babies. This makes her story not only unusual but significant.

     Adult babies may wear diapers or toddler clothes, sit in baby chairs, drink from baby bottles, sleep in cribs, and talk and act in a babylike fashion. Sometimes there are BDSM elements: The man may play a role in which returning to babyhood is a punishment to which he is forced to submit. Adult babies are not interested in sexual contacts with actual babies.
