When I potty trained my son, I had the same problem. What finally worked was "giving the problem to him". I told him that he was a big boy and he was the "boss" of his pee, and poop. I told him that I knew he could do it and the all he had to do was tell me and I would take him to the potty. Then I stopped asking him. I would sometimes remind him but mainly just let him deal with it. If he had an accident I would tell him the he was a big boy and he had to tell me, then give him a small punishment (no movie the rest of the day, not playing with a special toy, or just a few mintues sitting in the bathroon on the toilet). But I didn't make a big deal of it, I just told him next time would be better, and reminded him that he was a big boy and the "boss". It was 5+months before I tried this and it worked within 2 days! As for the night time, he still uses a pull up, my doctor told me it is more of a developmental thing then something you can teach! Good luck!
