I honestly waited until around 3-3.5 years. I'm happy I waited until I did because they were 100% ready and it was a smooth transition. A couple of accidents, but nothing major.

@blueismycolor yea for my son peeing on the floor etc. doesn't bother him. He doesn't seem to understand that's not what he's supposed to do

Mine is 3. We tried when he was 2, and he just wasn’t ready. It was an uphill battle. Now, as of the last month, he pees in the potty, but we can’t get him to poop in it. He is pretty much night trained and day trained though with peeing, and he keeps his pull-up/undies dry. But he still asks for a pull-up when he needs to poop. I’m trying not to push him too hard and plan on waiting a bit until he seems more ready for it. It’s just not worth the screaming and crying I get when I try to force it. He gets frustrated so easily.

My son didn’t potty train until 3.5. He had absolutely no interest, but he had to be potty trained to start preschool. I just put underwear on him and took him to the potty every 30 minutes. It only took him a few times of peeing in his underwear to realize how much he hated the feeling and he was using the potty consistently in a couple of days. Pooping took over a month before he finally got the hang of it.

My son is three. He just started getting the hang of it last month. He was more ready.
