Would you put your child on a diet ?

I belong to another website and one lady has put her DD age 11 on a diet saying she could do with lossing 5-10kilos but she doesn't look overweight. She lost 2kilos in the first week which her mum was very proud of but now her DD won't eat a thing.

It got me thinking when Kimberley hits that sort of ae would i do it and i think i wouldn't unless she was more than that over weight.
