I found on another website that it is a zinc deficiency. So, I gave him 50mg of zinc Thursday morning. No chewing, no bad behavior while at school. He did start chewing later on in the day. I gave him some Friday in smaller doses throughout the day. No chewing and good behavior. Saturday good. And, then Sunday forgot to give before church, and he was headbutting me during service and aggravating other children. I gave him zinc when we got home and he was calm the rest of the day.
What do you think of that?
I'm hoping this is the problem. The DAN doctor said it could be. I had been giving him zinc drops for several months because he was low and then stopped a couple months ago because I ran out. Seems to be a big mistake.
