Hell no, unless a child is morbidly obese they do not need to go on diets. I would only ever put my children on a diet if a Dr told me it was necessary and then I would only do it after seeing a nutritionist. Boy that woman is awful if she's doing it off her own bat because SHE thinks the child is overweight, the last thing a child (I think girl in particular) needs to be told that she is fat by her mother, she's going to end up with an eating disorder.
