If your child is fat it is probably due to his feeling unloved by you. Where do you get the idea it is acceptable behavior to call your child a fat@ss? Many children over eat when they have emotional traumas in their lives. Parents who emotionally abuse them or neglect them are usually responsible. It sounds like YOU are the one who needs a parental camp on how to unconditionally love a child. YOU are the problem here, not your child. I feel very sorry for your child. Good grief, I hope this is a tasteless joke!!
