I didn't get out of nappies until I was 5.

Nappies was not said

If he was wearing a nappy, shit wouldn't have fallen out. They're designed to contain. Plus if he wants to use the potty, he's probably not wearing nappies anymore.

Maybe OP posted it because this is FML and the incident in the story is fairly unpleasent?

English motherfucker! Do you speak it?

if they're already trained, pull ups make the kids in my class lazy, like, they'll pee in their pull ups even if they always pee in the toilet without them.

or you could just take the kid to the bathroom when they say they have to potty.

A giant turd from a two year old? As a mom of a now 15 year old I can promise you that does happen. At two, my Anthony Ray reached down into his undies and said "here". I mean, I have no idea how that monstrosity could even fall out of anyone's butt let alone a creature that (at the time) only hit 3'2". The best part? He blinked those long lashed green eyes at me, quivered his lip and " tay tank ooo mama!" (Say thank you mama")
