Yes I've had a parent put a diaper on me.
I remember when I was 6 years old I was with my parents visiting my aunt and uncle and staying at their house.
And before I went to sleep my mom laid me out on the floor and had a thick pampers plastic backed diaper ready and some baby powder.
She said that since I wet the bed I would need to wear a diaper while at my aunts house.
So she pulled my pants off and then wiped me up and then diapered me right in front of my aunt and uncle and my brother as well.
I felt embarrassed but quickly got over it.
My mom then left me in just my diaper and shirt and socks for the night.
Then the next morning I asked for my pants but she said they were in the washing machine and that my other clothes were out in the car and she was not unpacking them.
So for the morning I was wearing just my diaper, shirt and socks.
Then when evening came around and we were getting ready to leave she just put my pants in a bag and took them with her.
I asked her about my pants but she said that it would be okay to just be in my diaper.
She kept me in a diaper for the road trip back home which was around 10 hours.
So I rode the entire road trip wearing just my diaper, shirt and socks and shoes and she changed my diaper a few times outside on a picnic table at a rest area.
I'm glad she kept me in diapers on the road trip though as it meant I didn't have to hold my pee in.
I still wear diapers on road trips now as well and I would always diaper my own kids in diapers so they would not have to use the toilet or hold it.
