I agree the mum is an idiot.
She rates herself as being some mothering weight loss guru but if she was all that her kid wouldn't have become overweight to start with.
What type of mum puts her kids weight loss struggles in the public area? An attention seeking show pony, that's who. What kids wants every Tom **** and Harry to know her personal struggles?
This diet and publicity, combined with the mums own food phobias she is projecting on her child... Well lets just say the poor kid is doomed.
