I try to limit my contact with messed diapers as much as possible. The most I think I’ve sat or laid in one was overnight for an unspecified amount of time (went to sleep dry and clean, woke up wet and messy). But while awake, the most I am in one is for I think maybe half an hour. I’m cared for, so my partner can tell when I’ve messed and they help me get cleaned up and take a bath.
