A.,
I have always started my kids at about 16 months old. I have babysat and taken care of some many kids before having my own that I have leaned the best time to potty train them. The younger the better. If you wait to long to start potty training him it will be harder to do. I understand that all kids are not the same but one you start you can't stop this will only confuse him more. With both of my kids I went straight to big girl pants and big boy underwear it will take some time but they will get it. It took my daughter about two weeks from when I started to get the hang of it and my son it took about 3 weeks. The most important thing to remember is you don't want to go to many places when you first start out so that you can get them used to the idea of going on the potty chair or the big toliet. Hope this helps and good luck.
