A.P.
I trained my son at 3, but would have done it sooner if I had known how..... Now I do and here it is. Get some thick cotton training underware & and the vinyl underware (to help keep the pee from getting everywhere. Make them where both and as soon as my son peed in his pants he would come waddleing over and say he was wet b/c he peed. I would usually make him stand in it for a few minutes and let him know that is what happens when you don't use the potty, it is yucky feeling. This method only took 3 days and poop only took another 2-3 to overcome. He may have a night time accident once a month if that!
