I was raised vege along with my sister and my cousins were raised vegan. We weren't given any special foods to make up for 'meat'. Every one in my family are healthy and my vegan cousins are big men now, tall, muscly and ones even a bit podgy! smile If you think you are having a ballanced diet then feed your 12month old the same things.
My dh eats meat but both my kids started vege untill they were ready by my standards to eat meat. None of my kids have suffered from any illness's and are very healthy. My dd turns 1year this week and eats everything we eat, she still gets more vege meals as I feed her and find it easier than trying to touch meat etc.
I give her curry with enough rice to cool it down, pasta, curried vege sausages, salads and plenty of veg.
Dont stress to much as long as babies are happy and healthy your doing the right thing. smile
