My son did not potty train until he was about 3 1/2 years old. He had no desire to even try. When he went to daycare, they got him to go. What I was told to do was put him on the toilet every hour and give him a chance to go. We didn't get one of those little potties. I didn't have the stomach for it LOL. We got a "potty booster seat". I put him on the potty every hour and they did the same at day care and he was trained (daytime) within 10 days. He didn't make it through naps or through the night for a few months longer. There is a muscle which develops at WAY different times in every child. That is why some potty train at 2 and others not until 4. If that muscle is not developed then they cannot "hold it it". We would have him not in diapers during the day, but right before naps, long car trips, and bedtime. When he finally woke up dry for a week, we took the diapers off completely. AND we did NOT use pull ups. That sends a mixed message in my mind. If they look and feel like underpants, then it's ok to urinate in your underwear, know what I mean? Anyhow, by the time he was 4, he was done completely. No accidents. Want a good tip about cleaning up accidents during the night quickly? Put on a fitted wee wee pad, a fitted sheet, another wee wee pad and another fitted sheet. This way if there is a nighttime accident, you just have to pull off the first set of weewee pad and sheet and the bed is already made. No changing sheets in the middle of the night. Everyone's happy. Good luck, dear, and don't lose hope. One day you'll turn around and notice the job is done. I don't believe in the reward system for anything because I believe it punishes them for when they don't succeed as well as rewards them for when they do. I don't agree that it helps their self esteem any. The star rewards are fine for chores such as making his bed or doing his homework or finishing his lunch, but for something that he just can't help right now, it sends a negative message in my opinion. Just celebrate his successes and downplay the failures. Besides, my son never fell for it anyhow. After 3 days or so, he learned to live without the sticker or checkmark on the chart, etc. so it was a waste of time. I hope this gives you a little encouragement.
