Hello! Our grandson (GS?) has just turned 4. He's reading and loves anything to do with numbers, patterns, puzzles. He's taught himself to write both numbers and the alphabet, and some words. Loves building with Legos. Carries on conversations that leave us struggling to catch up! We haven't had him tested yet.

My question concerns potty training. He has decided that he doesn't "like" having a bowel movement, so he won't. He holds it until I don't know why he doesn't feel sick. And then will sit on the toilet forever, not do anything, go play and then GO in his underpants. We've tried rewards, time outs, withholding toys, you name it. Even telling him that he can't go to school if he can't go to the bathroom. He tells us then that he doesn't want to go to school. So that doesn't work. Other than this he is such a bright, happy, loving child. It's very frustrating. Does anyone have any suggestions? Thanks!
