ok i have a 7 year old sister, she'll be 8 in april. she weighs 41 lbs and has lupus. my dad and step mom have the worst eating habits and my sister barely eats at all. tonight for dinner she had 2 wendy's chicken nuggets and a few fries and dairy queen. thats just a example but its pretty much her daily routine. she is soo thin it makes me sick to my stomach, but i dont know how to get her to eat better. on top of all of it my step mom is a fat f-ck who thinks you dont need to eat vegatables because she didnt eat when she was young and doesnt still now. i dont know what im gonna do but i cant take it anymore. i wanna see my sister get healthy and its not gonna happen with the way she eats. any input you guys can give me will be a great help
