I have never forced a kid to expose their diaper with no pants on a busy commercial street.
However I remember last summer there was a boy of around 8 years old who was wearing pampers cruisers size 7 diapers.
His mom took his shorts off and said that he would be just fine in the diaper.
His shorts got wet with pee from the other diaper leaking so his mom changed his diaper and then left his shorts off.
He didn't like it but his mom spanked his legs and told him that he better do what he's told or he was gonna be wearing diapers until he was 18.
She said you're gonna wear your diapers until you can stop peeing your pants.
She said that he was wetting his pants everywhere on purpose and so she made him wear diapers for it.
She also gave him a pacifier and made him suck on the pacifier.
They then walked down the busy street and then she took him to the park to play on the swings and slide and play around in the park that way.
I wish it were me.
