maybe you don't need books!
I was raised veggie, and my son is veggie too. (now 3yo). I am not sure you really need books... I was given two books as gifts but found them not that useful. I flipped through that superfoods book and it just started making me anxious... I guess if you have made a big dietary departure from your own childhood, maybe books can help you imagine what veggie kids eat.
Here is what I wish I had been told: trust yourself and your child to know what is needed (regardless of what other parents might be doing/reading/saying!). You probably already know how to feed vegetarian people nourishing and tasty food. Kids are really the same. They eat smaller amounts, and food has to chopped or mashed (and sometimes, to my taste, overcooked) if they don't have enough teeth to chew with. And, at least at first, you can introduce new types of food one at a time and watch for allergies.
Do other babies really eat a lot of meat anyway?? I think that breastmilk is the major source of nutrition for AT LEAST the first year, and as long as you offer a variety of foods, and stay away from sweets, refined grains, and excessive snacky/packaged type foods, most kids will do a good job selecting the foods they need to grow and be healthy.
My son was not much of an eater until he turned one, and then became a voracious omnivore. I know several other kids like that. And then we know some kids who took to eating right away. I don't think its really in your control anyway! He never liked "soft" or baby foods, and believe me, I kept trying. Finally, I just relaxed about it, and accepted that he just liked normal food. At first, he loved things like fresh ripe fruit, home-made fruit sauce, some veggies (and which ones he will eat seems to change frequently, even now, so I just keep offering), oatmeal (warm, and then later cold and cut into chunks for finger food), polenta (same system), beans or lentils (beans whole, or either one cooked and mashed), avocado by itself or spread on thin whole-grain bread, tofu pan-fried with garlic and a little tamari, little crustless quiches (cooked in those individual souffle dishes) with grated/minced veggies. Brown rice well cooked. Whole wheat buttermilk pancakes or waffles warm and then later cold for snacks.
Once he could eat "regular" food (i/e once he had a mouthful of teeth) I stopped fixing special stuff and just offered him (within reason) pretty much what we were eating. We still make sure keep plenty of fruit and nuts around for him, but really I just try to make sure he's getting a variety over the week of different things, and make sure I am aware of the sweets/treats (that can really throw him off).
I did get some flaxseed oil and kept it in the fridge to add to oatmeal or plain whole milk yogurt, since we don't eat fish. If you are vegan, or have serious allergies that preclude whole types of food, then you probably already know the nutrients you have to watch out to include (or supplement).
Have fun!
