I agree with sunny days all my picky eaters have shown improvement this way. It may take little while for some, but when people or little people are really hungry they just have to eat. What I personally do is try to add things that they like to our menu (along with foods that they thing they do not like). If they like eating frozen or fast food I just make a healthier version of it (like adding flaxseed or shredded carrot hamburgers; sweet potato to the egg mix of chicken nuggets, etc)
