All my difficult children are like this, although my oldest and youngest are way worse than my middle. Can he write/read already? What I've set in place is a spiral notebook that my difficult children keep with them at all times, one for the car, one for the house and one for school. The one at school was just for my oldest difficult child last year, but if the new teachers need it, we'll start it for them. If they want to talk to me and I'm talking or someone else is talking, they write it down. At first I was very insistant on this and explained that if they didn't use it, it would change their color, because interrupting is rude. Now that they've gotten use to this, I don't have to use a color chart. I still have problems when I'm on the phone, my oldest and youngest difficult child literally do not see the phone at my ear. So I will put my hand up, as to say "stop" and then I point to the phone. Then they either go away or they write it down. Oldest difficult child has a problem arguing when he is sure he is right. What I explained is that sometimes, if you wait to talk about it, then its not really arguing. That you need to give people time to cool off and think about it. So he uses his spiral to write down his thoughts about disagreements. Then later he asks to speak to his teacher. It really helped last school year, we haven't started it up again this year yet.
