For those who are concerned about nutrition I would recommend checking out The Sneaky Chef at the library. I got this book when DD was around 2 to try to figure out how to get more veggies into her diet. It is amazing how you cannot taste the veggies that kids are most resistant to eating in their raw or cooked form, when you mix them in more desirable food choices.
An example would be: I steamed carrots and boiled sweet potatoes. I put them together in the food processor and pureed them. I then took a chicken breast and dipped it into egg, rolled it in a mix of wheat germ and italian bread crumbs and then coated it with the orange puree.
I baked it in the oven and when it comes out it is the most delicious chicken tender, tastes slightly sweet and very yummy. My DD shovels this chicken down and it counts as 2 servings of veggies along with lots of fiber and protein.
I know that it probably isn't the best thing to "trick* your kid to get them to eat veggies, but I feel better knowing that her nutritional needs are being met and continue to still offer a raw or cooked vegetable with dinner to try to get her to develop her palette for these things on her own.
It has gotten much betrer since she was 2.
