My son is 3 and a couple months and is doing pretty well in just underwear. Just this week he's only had one accident all week, but still wears a pull up to bed. He just starting "telling" us when he has to go rather than us putting him on there every 40-55min. My question is this... when should we encourage him to stand and pee? Is this something that comes way later and I shouldnt worry about or what is the norm? DH prefers to sit and pee so DS hasnt seen him stand to pee lots. Now that it's going to be nicer outside should we encourage him to do it?
