difficult child may be developing a tic. I have noticed he is biting on his shirts around the shoulder area on both sides to where they are wet from his saliva. Also notice he is jerking his neck around (similiar to someone trying to get water out of their ear) but this is very slight. Not sure if these are tics are not? Any advice ? I am going to call psychiatrist in the AM but from research I have done, Tics usually have to run their course ... One more thing to worry about ... On the brighter side of things, difficult child has been an absolute angel since school let out. Keeping him nice and busy is helping. Thanx !
