this is merely an excercise of his control. you can try two things IMO
1. start letting him on a daily basis throughout the day make his own choices about lunches, what to wear, what to watch, and so forth. let him feel as though he does have some control over his own life and choices.
2. give him a daily dose of mineral or castor oil, like a half teaspoon or even a prune juice with breakfast and then sit him down on the potty every day at the same time and read to him, read read read and talk talk talk for about 40 minutes.
the oil/juice will prevent him from being able to hold it, and the reading time allows him to relax and get on a schedule with regular bowel movements. Within a few days, you should have some regular routine going.
Right now about the only thing he can control is his bodily functions and behavior, so he's enjoying it as much as he can. GL
