Whatever you do, don't just trust your doctor on this one. I love my doctor, but he's no nutritionist, and every time I turn around, he's telling me to cut dairy. It was the first thing he told me to do when my daughter had excema, and I made the choice, excema or not, she needs the essential fats, protein and calcium inherently present in organic cow an goat milk, not calcium fortified soy etc which is OK sometimes, but not a good full time substitute before 2 years of age. The fats alone in milk are crucial for brain development. So FIRST, find out how to replace those elements effectively or continue to nurse if you possibly can. Second, be absolutely SURE she is allergic to dairy-get lots of opinions. Dairy allergies are EXTREMELY over diagnosed and a lot of kids are having very valuable nutrients taken away. Good luck! ps, We're healthy vegetarians too, I get it, that soy is supposed to be the end all be all substitute, but it isn't and there are a lot of studies showing that too much soy is harmful. Foods made to look like other foods -milk, cheese, patties, etc, are HIGHLY engineered. We do occasional soy milk, occasional organic tofu, and for a real treat, occasional soy dogs. But don't replace all her milk with soy!
