When I was a toddler I was dressed in just a diaper and shirt and also during my Kindergarten years my mom did put me in diapers for the rest of the summer because I had to wear diapers during the school year because I wet my pants.
So during the summer when I was 5 years old and almost 6 years old my mom dressed me in just a diaper, shirt and shoes.
I went in public like that to the store, doctors, etc and at home I was outside playing in just the diaper and shirt and shoes.
It felt great to me and I actually loved it.
When I have kids I"m gonna dress them in just a diaper and shirt and shoes and take them in public.
At home when it's warm they are gonna be in just a diaper and shirt and maybe socks just like the diaper boy Tommy below.
