Have I ever worn a messy or dirty diaper in public?
Well yes I did when I was a baby and when I was 4 years old before I was potty trained.
I can remember being 4 years old and wearing diapers at the park with my parents and I had pooped the diaper and my mom noticed it and she changed my diaper right outside on the ground.
I was getting to where I was embarrassed about things and after that deal with my mom changing my diaper in public at 4 years old I started going to the toilet.
My mom used to tell me that if I used the toilet instead of the diaper I would not need to be changed in public.
So she sorta shamed in into potty training.
Now I don't wear a messy diaper in public because I no longer wear diapers but if I did and pooped I'd want changed right away because people would likely notice.
