Is there something wrong with my little sister?

little kids go through growth spurts,and when they stop so does their need for so much food.She is ok and will eat what her body needs.Or she could be upset about something.But it is most likely the first idea.Don't worry unless it doesn't go away.

maybe she loads up on snacks.

or has a stash in her room. maybe shes trying to be anorexic or lose weight. i tried to lose weight by not eating much once and it destroyed me. wait her out and look if shes eating snakcs or have a stash in her room. if shes not eating on purpose the effects will come , lack of energy lack of moral ect..

and every day ask her if shes ok. either her sideeffects from not eating will show or she will bail

probably not..

kids always have these ups and downs with food, like for a month theyll eat tons but then for a while they will eat very little.. if it lasts more than a couple weeks then be worried

thats how i am. i eat a bunch for like a week and then just not eat a lot. it just happens naturally. if it goes on for a long time and she isnt eating she could be anorexic. ask her questions and stuff. its great that you care for her so much. my brother wouldnt even notice if i looked as skinny as a skeleton

Your parents will be the best judge of that. And you can ask her if she feels ok. It is a good thing that you are so concerned....
