DS1 (age 8) seems to have a nervous tic. I drives me crazy and I want stomp my feet and instruct him to stop it. But, that of course won't help so I don't.
He blinks uncontrollably. And he also chews his fingernails (and somtimes his fingers). Sometimes if I tell him to gt his fingers out of his mouth, he starts blinking.
If anyone has any experience or advise I would be most gratefull.
