Hi J.!
My 3 year old, (just turned 3 today), has been working on the potty training for several months now. He was interested, then he wasn't. We talked it up to him a lot, he went in the bathroom with daddy all the time, to watch daddy, and we received an Elmo potty training video for Christmas, and he loved watching that. We kept telling him about big boys, and potty time and such. Finally he just kind of did it. We kept his lil potty out for him all the time, and he really just did it on his own. We only had a few accidents with number 2, and went thru a lot of number 1 accidents, but he eventually learned the "feeling" he had before he had to go. I've been told over a hundred times, they sort of just take to it on their own time, their own way. I don't consider him fully trained yet, as he's a lil scared of the normal toilet, and so when we go out in public, he's in a diaper or pull-ups (and overnight), BUT I constantly ask him when we're out, if he has to go, and we try to go into every public restroom so he can be familiar with them. I'm figuring he'll just take to all that when he's ready too. I'm not presurring him, I don't want to scare him. But he does great when we're at home, he'll even take off his diaper to go, so I'm going to let him do his thing! I would just start talking to your son about it now, introduce a lil potty or one of those seats to put on the normal potty. Show him videos like the ladies have mentioned below me, and I think just talking about it and introducing it will at least get his wonderful, smart mind's gears turning, prcessing the info you are providing to him. Our son is real good at listening to our words, he knows what we're saying to him, is something he needs to hear, so we just talked it up to him. I think boys may be a litle more stubborn, BUT my cousin didn't get her daughter trained until after she was 3.5 years old. I think it depends on how much time you spend on it. Don't pressure him, but definitely start NOW. Also rewards are great...we had suckers, and M&M's, we'd give him one M&M if he went number 1 and two M&M's for number 2, then I went to offer him that, and he said, "No tanks mama, no more no more". So I thought, okay, nice...hmmm...and he just goes now, never asking for anything in return. He knows it's easier to do it in the potty than in his pants. And everytime he goes now he runs out and announces it, he is so thrilled with himself, because we have always been positive about it. When he announces it, I always try to respond to him like I did the first time he went, we want him to know how proud we are of him, what a big boy he is. It's great! They are so smart, never doubt what they are capable of, so I would begin with your lil man NOW!! I think as they are turning two, they are more vocal and are more understanding of you, they listen, and the earlier you can get them trained the easier.....GOOD LUCK, keep us posted!
