As a bit of background my DD has been having issues around eating for a while. It started at school getting easily grossed out by other kids showing eachother chewed up food in their mouths as a joke and spitting food out if they didn’t like it etc etc. it escalated to a point where she wouldn’t eat lunch at school at all. Felt sick at the thought of it and would go literally all day without eating. The school were very helpful and arranged for her to sit at the back of the class (during covid they had to eat in class) etc but nothing really worked. She would eat absolutely fine at home and has no body image issues. It is just being too close to other people eating that was the issue including if we take her to a restaurant or cafe and it is busy. She recently had the government growth test done at school and is borderline underweight and on the 3rd centile. Very very slim and at 11 not far of starting periods. I became really anxious about her being underweight and started trying to increase calories with lots of treats and deserts as well as frequent high protein and carb meals. However the last week or two she often eats very little of her meal saying she is bloated/stuffed etc after a few mouthfuls but when offered cake/ice cream etc 5 minutes later will happily eat it. If I say “if you don’t eat the dinner you don’t get desert” she will simply say she can’t eat anymore and will fairly happily go without the desert and go to bed on an empty stomach. I’m at a bit of a loss. Is it unreasonable in the short term to let her eat what she wants to get her to a healthier weight even if it’s too much junk and not enough real food?
