DS2 (7 years old) seems to collect tics like Pokemon cards.
At the moment he is constantly doing little jumps and flicking his head to get hair out of his eyes (it isn't long enough to reach his eyes). Before that he was snorting (clearing nonexistant phlegm out of his nose) and before that sucking spit in through his teeth.
They aren't real Tourettes-like tics, in that I don't think that they are completely involuntary, but he gets very upset when you tell him to stop and says he can't.
I'm partly worried that it is a sign of something underlying, and partly because I don't want him to get teased or isolated at school.
He has suspected dyslexia, and describes himself as being 'like Brick from The Middle'.
Should I worry, ignore, try to help him manage, go to the Doctors?
