Dinky, I was going to ask the same as Bec (Tigergirl)..have you listened from outside the toilet door, although there is also the issue that they can throw up quietly. My friend had both bulimia and anorexia and used to go to the toilet, but you couldn't always hear anything as they cover it up and know how to throw up without noise. She'd also tell you she'd just eaten or something, but you could tell if she was binging because she'd barely chew the food she was that hungry.

Jo, I would definitely have concerns if Jess is writing down what she is eating and the sit ups...that can be a classic sign.

When my son was 5 he told me he was fat! I couldn't believe it and he would tell me he needed to exercise, so I just kept on telling him over and over that he wasn't fat and even made sure that there was things like milo and similar in the house because he can't resist them but if he did stop with those things then I'd have been majorly worried, but he did get over it.

I hope that this gets better for you both.
