It'll be up to them if they want to wear or not. If they don't want to wear anymore, it's their choice. I'm not going to force them to stay in them. I have heard about kids still being in diapers because they were never potty trained. There was a kid in my brother's grade who wore them and this was back when he was in 2nd grade. Why did he wear them? I don't know but I do know he wasn't in a wheel chair or psychically disabled in anyway.
When I was 14 I heard about a boy in third grade in my town who wasn’t potty trained till 2nd grade. I asked my speech therapist why and she said some kids are just potty trained later than others.
My boyfriend’s daughter wears them because she likes to. He and his girlfriend (now his ex) could never get her potty trained, they tried till she was eleven and then they put her back in them telling her either she wears them or she stops wetting and messing herself and she picked diapers and has been wearing them ever since. She has gotten teased about them but she still didn’t give them up and she told all her friends she wears them because she has a medical condition.
There are other people out there who like diapers too. It’s all over the internet. There is diaper lover, adult baby, and teen baby. I chat to many diaper lovers online and almost all of them are AB’s as well. I even meet diaper men here too. I am going to meet another one again today who is traveling the states and he is from England.
There are a lot of fetishes out there; BSDM, golden showers, water sports, spanking, foot fetish, shoe fetish, infantilism, diaper fetish, scat play, and I know there are men out there who like to dress up as women, and there are men out there who wear bikinis or thongs.
