My eldest DD was diagnosed with anorexia at 9 so I would really be keeping a watch on her. There is so much pressure on girls to look good and it is starting younger then what we ever had to put up with it. My DD is still battling weight issues so don't leave it to long to do something about it. Maybe a trip to your GP, and a talking to by them, would help her realise that she is just fine but maybe not. So giving your GP a heads up would be beneficial. hun this is a hard road
