D.P.
I have a 34 month old little boy. He used to LOVE his veggies, but doesn't anymore. Now I "hide" them. If I make a meatloaf, I add shredded carrots or pureed squash. He loves pizza, so I chop spinach and tomatoes and put them on before the sauce. If she'll eat eggs, there are lots of veggies you could probably sneak in. If it's protein she needs, you may just want to take a stab at something like Pediasure or any of the snack bars geared towards kids. They are sometimes high in sugar, but they are loaded with vitamins, minerals and protein.
