I don't know, but I remember reading an article about two vegans who tried to nurse their child on home-made soy milk and they got it taken away by social services because of malnourishment and neglect. For one thing, I don't know why you would home-make your soy milk instead of just buying it, because some of the stuff you can buy is really good. It even says in big red letters on the side of Silk boxes "DO NOT NURSE BABIES ON SOY MILK"
