beat him beat him beat him! kidding -- here's what i've heard worked w/ a couple of friends of mine w/ the same sort of situation and child: PATIENCE, they actually are testing you to see how far they can go and if you haven't been consistent in the past w/ (a) being calm in the face of their crazy, (b) consistent in the way you handle it -- which is listen to why he doesn't want to go to school, not just say "you have to go", but make him feel like his feelings mean something which means taking time to talk to him about his feelings about, well, everyting/anything, really engaging yourself and legitimizing (if that's a real word:) his feelings of self, and (c) being firm about going to school and all the other struggles he likes to put forth, without yelling or showing the reaction he's looking for (he really does WANT you to lose it), it kind of puts you on the same playing field as he is when you do lose it. If you can find it in yourself to remain calm in the face of it all, over time you will really see some results, you will earn his respect and he WILL want to please you. It seems (as you mention) his father has some power of him through fear, but that's not what you want (who does???), so just try this, it worked for friends (and family) of mine, and it's kind of the way SuperNanny does her work too. :)
