I have a 3 year old who is just starting to really want to go potty. I started the whole process when he turned 2, but he is just now able to tell when he has to go. The best peice of advice I can give is don't force it and buy Elmo Goes Potty Video. My son, in only 2 weeks, started showing a real interest in the potty, and the video teaches them proper hygeine, like washing their hands. I am not big on letting my son watch a lot of TV, but I will let him watch this video anytime he asks. I have even watched it with him!! As far as getting up in the middle of the night, my son still does that, too. Our pediatrician told me not to be worried because as long as he isn't wanting a whole lot to drink, it could be that he sleeps with his mouth open and it gets dry. I wouldn't be too concerned yet, and keep in contact with your child's doctor! Let me know how it goes!! Good luck!
