I'm very worried about my dd, who has always been a fidget, and at different points in the last few years (since she was about 3 and a half) has incessantly done these sort of movements with her hands which seem either like a tic or like a nervous habit, I'm not sure which. She scratches her other fingers with her thumb, or scratches her palms, or, more recently, clenches her fists. She does this pretty constantly.
Usually it lasts about 3 or 4 months, then goes away again, then comes back, often in the autumn. Does anyone have any experience of something similar? I'm worried this is the start of Tourettes!
Thanks.
