We started at 2 yr 6 months, when he started showing signs of being ready. He often told us when he needed a new diaper, so we got him a potty and put it in his main area of play so he would see it and remember to use it when he needed to go. We tried putting him in underwear, and tried pull ups, but neither of those got us anywhere. As long as he has something on his butt he was presumably confused and felt it was OK to let it fly. We opted to let him go commando, and just wear sweatpants around the house. He knew there was nothing on him he could pee in, so he always went to the potty as long as he was like that. We still used pull ups when we took him out in public for 1-2 months after starting, because he was afraid of the large potties in public. We would always ask him while we were out if he needed to go to try to get him acclimated to the idea of using one away from home.
