One time I was sick and in bed. I didn't wear a diaper and had to pee but was too weak to get up so I ended up wetting my bed. It still made me feel like a baby, but the clean up was too yucky so next time I think I'll wear some "protection."
I put a little bit of both. I think I want to be a baby because I was bullied at school a lot. But I also remember that I never liked growing up and having responsibility. I think it was a combination of both.
