DD has lost a lot of weight over the last six months and now looks skinny (very). She skips breakfast and seems very aware of not wanting to eat too much. Mostly she appears to eat normally but she still seems to be getting thinner. I'm worried she might be making herself sick and don't know how or when to intervene in case I make nothing into something. If anyone has been here before I would appreciate some advice. Her dad thought he heard some retching once. Thanks.
