Ds has recently started to shake his head from side to side in a jerky movement, usually when he is sat lining things up. He is currently sat across the table from me, playing with a chess set, well lining the pieces up and rearranging them and he gets very cross with me, if i look at him while he is doing this and tells me to stop looking.
He has had various tics and verbal tics which come and go.
Previous OT seems to think its a sensory thing, CAMHS think its an anxiety thing. Or perhaps a bit of both?
Anyone else have tics or any ideas on what causes them?
