I'm DL and it was back in about 1963. I was 4 to 5 years oldf and I wet the bed so every night I was diapered in cloth diapers and plastic pants for bed. I remember one night sitting on the couch in my footed pajamas becoming excited that I had on diapers and plastic pants as my dad read me a bedtime story. i kept pulling the front of my pajamas away so I could look down inside at my diapers and plastic pants. that hooked me for life on diapers but because I was never treated as a baby or humiliated or anything, I became a DL and not an AB.
