She probably doesn't eat other foods cos she knows you will give her what she wants. I agree with the previous posters about dropping the foods with empty calories she is better off eating nothing then them. Dd doesn't eat something one day but I'll offer it to her another and she will. Try putting a variety of healthy foods on her plate if she eats it she eats it if he doesn't she doesn't, try not to worry to much. She will eventually eat it and will eat if she is hungry.
