I don't fight with food ever. You can't make a kid eat. I serve and they either eat or don't. I have one kid who will go all day without eating because I won't give treats for afternoon snack which she tries to hold out for if they haven't eaten one healthy thing at morning snack or lunch. She tries the old, "I'm thirsty and want some milk." routine too to try and fill up on milk but I switch it to water on days she refuses to eat which usually motivates her to eat something. I flat out tell the parents it is a power struggle and battle I refuse to take part in and that's all there is to it. I will win or they go hungry.
