dt1 really doesn't seem to be himself at all atm. He has just started preschool which may be part of it, and is very clingy and is not going to bed at night. So he is overtired as well. He keeps headbanging when I say somethign he doesn't like or tell him off. I've tried ignoring it, but he is still carrying on, I don't know what to try next. We have wooden floors, so he must be gettign a sore head! I was wondering if maybe he was ill, but he has no other symptoms.
