I did at Disneyland when I was 8 years old. I had been real sick for months and my mother would totally freak out every time I went into the hospital. She was certain that I would catch Polio and die. I didn't, but she was so overprotective that she kept me in diaper all the time that I was recovering.
Anyway, when the doctors said I could get out of bed and start being a kid again, Disneyland had just opened, and for my 8th birthday that's where we went. I was really Embarrassed when mother would take me into the ladies room and change me. There were always a lot of other women in there changing babies but I saw a lot of older kids, some around my age, being changed also. Up to then, I really thought that I was the ONLY kid in the world who still had to wear diapers. This was late in the fifties so they were cloth diapers and Playtex rubber pants.
