I don’t know how well the doctors had described my medical issues to my aunt and uncle, but I got the impression that they were both a bit surprised and concerned when several weeks had passed and it had become apparent that I wasn’t just going to become magically toilet-trained overnight.
Aunt Lydia was by far the most understanding of the two. I had always hated it when my parents or my sister had changed my diapers, but Aunt Lydia managed to do it in a way that didn’t make me humiliated, embarrassed, or ashamed of myself. So, while I could change myself without issue, and preferred to do so, I could selfishly admit that I took advantage of her willingness to change me on more than one occasion.
