E., when my son turned 3, I tried to get him interested and tried to start potty training. I could just tell that he wasn't quite ready for it yet, so I backed off and decided to wait a little longer. And at 3 and a half years old we had very successful potty training. Every child is different, but boys do tend to do it a little later. Follow your instincts. If he's not quite interested enough yet, I would suggest waiting a little longer until he really wants to be a big boy and wear underwear, then go full steam ahead with it. The quicker you get him into underpants once you've started, the better success you'll have. If they wear the diaper or training pants, pretty soon they figure out that they can just go in that. When he's ready and you have a good week or so where you'll be at home with him a lot and be able to spend time watching him closely, go for it. I would recommend using a doll or something that he can teach to use the potty. Teaching is the best way to learn. We used a baby Elmo that came with a little potty and said he had to "go". That's also a good way to see if he's ready or not. If you start trying when he's not quite ready, it may backfire and end up taking longer. If he sees the potty as a negative thing because he had to sit on it forever when he really wanted to play, he might put the pottying off even longer. With toddlers, everything has to be a game and be fun, or they just aren't interested. I would recommend a reward system. It can be used for potty training, then you can continue to use it for other good behavior that you want to reinforce, like cleaning up toys. Me and my son made a "Big Boy Chart" together. I made the lines and words, and he went over them with a crayon and decorated the chart around the edge. Helping make the chart, gave him more pride and interest in it. Every time he used the potty, he would put a sticker on it. When he filled up a row with stickers, he would get a surprise. It was just a cheap, neat toy (about a $1), but he thought it was the greatest thing in the world. He's 6 now, and we still use that system when we want to reinforce something. We also had "potty parties". I got a bag of some cheap party blowers(in the very beginning of training -to make it fun), and if he "went" on the toilet , we would blow them and sing "Potty party - Woohoo!". Of course, he loved that. Also, my son spent a couple days a week with my nephew, who's 7 months older than him(who also mastered potty training at 3 and half). My son got to see him going on the potty every time and was motivated. We put him in underwear right away because he went on the potty every time that day he started, and he's never had an accident unless he was sick. I've always made sure that he empties his bladder right before bed, and I try to limit his drinking after a certain time. We used a potty seat ring that you put right on top of the regular toilet, from the beginning, so we never had to transition from a little potty and that way he was always used to the big one and the flusher. Don't frustrate yourself if he's just not there yet. Don't worry, it'll definitely happen! Good luck!
