Adult child I call themI once had an acquaintance a bit like this. On the surface she was quite accomplished: working in the arts, living alone in a flat in West London. But it transpired she was something of a babywoman (female equivalent of manchild) whose parents paid her rent for her. It was like she never quite made the jump into full adulthood. Even her “boyfriend” of a decade was someone she only saw infrequently.
