My DD (12) in Y8 now came home last night and told me 2 friends from her former primary school friendship group are having - for want of a better term "thin-ness competition" issues... (she left the group because she was always being called "bigger", and told she ate too much - 50th centile for height and weight - so totally average!).
Neither eat breakfast, or snack, both tip their lunchbox contents straight in the bin - and neither eats much after school as they tell their parents that they "want a bigger lunch" so eat less at tea time... they are quite open about this amongst school friends.
It worried my daughter because when they changed for PE for the first time this year she said one girl looked like a skeleton. It took a lot for her to tell me about it because of the issues she had with them about her own (normal) shape in Y8 - so I know it must have shocked her deeply...
I don't know what to do - other than I think I should do something - has anyone any experience of this sort of thing?
