Thanks LC, I will do the food diary I think. I just don't want to seem like a psycho parent. Before I saw this GP today, no one has ever said anything about her weight, let alone BT's etc etc. The Gp today mentioned BT but said that the pead would do that if he thought it was neccessary. I said "some kids are just small right? I was a very small child" and he said "yes, but we want to rule everything else out too."
