I saw my sister and cousins that lived by me in diapers and it felt like I was missing out on the fun. However, after my sister was potty trained, one time at Sunday school, I went to the bathroom only to see a teacher putting a white diaper on my sister while she was standing up. I was kind of surprised, nervous and maybe jealous but I didn't understand what I was feeling so I said "hey, don't do that. That's not good to." I was scared to say the word diaper. After my sister came out of the bathroom with her clothes back on, I asked her what she was wearing and she answered a diaper. I asked her why and I don't remember exactly what she said but I think it was something like "I don't know" or "because Mom told the teacher to put one on me." Near the end of that same sunday school, I saw another adult putting a blue diaper on an otherwise naked boy who looked bigger and older than me in the middle of the room. He did seem old for diapers. He was lying on his chest and by that time Mom was there and she asked me teasingly "what's she doing, what's she doing." I felt like it would be embarassing to be in the boys position but I for some strange reason wished that I was. I felt like I was being deprived of something, embarassment or not. While in the car on the way home, I asked mom why my sister got to wear a diaper that day. Mom said that she had wet her pants that morning and rushed for time without a spare pair, my mom just told the teacher to use a diaper for the time being. Right away, my sister was changed out so I never really got to see her in it.
One time I was over at a a parent's friends house when I was younger than five, maybe four. I see the kid briefly walk by in a diaper and then get changed out. I have weird feelings not understanding how to react. I was afraid of asking a lot about them because even then I didn't want people to think I was somehow interested in diapers. Maybe I wasn't comfortable with my diaper interst myself. His mom told me he wet the bed still. That was the only time I saw him before he became dry at night though.
Another time when I was about 7, I was at a neighbors house across the street. The family had boy/girl twins and the boy one day showed me a diaper, claiming it belonged to his sister. He said let's throw this up to the top shelf where she can't get it. He said like it was dumb that his sister liked to wear diapers to bed and she just whined for her parents to put her in them. Due to the boys attitude, I was afraid of showing any more interest or asking the girl or parents about it. But it was weird because this was my first clue that someone else might just like wearing diapers too. Surely he was joking, covering up for his bedwetting or trying to trap me into talking with his parents and reveal my interest.
Later on in third grade, I thought I heard out of the blue one girl say to a boy in my class "You're wearing baby diapers?" I didn't know why but I couldn't stop thinking about if I had really heard that and looking at the boys pants during recess, trying to determine if he was in a diaper.
A few years ago, I was over at a neighbors house for his high school graduation party. He has a younger brother about 10 years younger who I know was in diapers until age 4. (lucky kid, he'll probably actually have memories of wearing them.) Anyways, at one point when I was passing by, I overheard him say something to a friend like "and if they don't succeed, they have to wear diapers." -"Why diapers" -"I don't know," and at that point I kept walking because I got nervous but I really wished I had hung around longer to hear the rest of the conversation. It made me wonder if he was interested in diapers, since he wore them until 4, maybe he really liked them?
