DS2 (nearly 4) has been ticcing for a couple of months (vocal, and shirt tugging). But now he's started to pick at his nails. This doesn't bother me tooooo much (I don't see it as any worse than nail biting), but he's just pulled off an entire toe nail :( This is most unpleasant!
Is this another tic? If so, is there anything I can do to get him to stop?
Thank you x
