My ds has a squint in one eye - not all the time, but occasionally. It is something that has developed recently in just one eye. I thought it might be a lazy eye, but my childminder mentioned she had noticed it and that he had a white eye reflection in one of his photos (same eye). I don't have many recent photos to compare it with (he is difficult to keep still long enough for a photo!) and am concerned. Should I worry? He has appointment at docs on Thurs.
