DS will be 3 in May. He has not worn a diaper since Christmas and is doing awesome, zero accidents, I don't have to remind him to go at all. I had no idea how to train a boy so he's been sitting. I know at some point he's got to stand, but how and when do you make the transition? Did you let your sons sit for this long? What happens when you go out? We have the little potty at home, but he wont be able to reach up to a public toilet.
