Some good sources of iron:
green leafy vegetables, beets (my kids love these and you can put them in smoothies!), asparagus, grapes, bananas, figs, dried fruits, beans, soybeans, sunflower seeds, meat, fish, poultry, peas, eggs, whole grains, lentils, millet, pumpkin and sesame seeds, and blackstrap molasses. (got this from my infant/toddler nutrition book).
You can put the molasses in all sorts of things I'm sure if you're creative!
