My dsis(15) isn't eating much, and is restrained to the point of taking one bite of a biscuit and leaving the rest. She's not overweight, but I am and I wonder if she's trying to avoid getting big like me. She has CFS, which might be reducing her appetite (she says she's not hungry a lot), but I suspect the lack of food doesn't help her energy levels.
I'm getting frustrated with her because I'm concerned, but I'm sure there are better ways to talk to her. Can anyone tell me how to help?
