My DS is 3yrs, he constantly makes a certain noise which he repeats over and over, for minutes at a time and at the same time he opens and shuts his hands ( like doing twinkle twinkle little star type action by the side of his head.) He doesn't look at his hands, but I guess he can probably see them out do the corner of his eye. They don't touch his face. So I suppose my question is, is this an indicator of a specific SEN? I know it's an unusual thing to do. The noise can appear at any time, running about, playing with others, just at home or in sitting the car. I feel like he has done it 9 thousand times today
He has probably been doing this for the last six months, so I think it's more than a phase. Any ideas?
