my dd, 8, has been sneak eating at her father's house. she only does it over there. i wonder why? but either way it isn't good. i started having eating disorder problems at her age and this is one of the signs. i'm concerned about her. he feeds her fast food all the time and he says she gets snacks. she has been gaining wieght like crazy! how do i tell him to keep an eye on her eating habits without offending him?
