I raised my child basically milk/dairy free until she was over 3 years old. Until she was actually 6 or 7 I didn’t go out of my way to even buy milk on a regular nutritional basis.
I use to make my soymilk from beans, grind, boil, squeeze it out in cheesecloth. From this I made yogurt, sometimes, or tofu. Usually I just bought tofu.
The “fear” or “bad rap” soy has gotten is the fear of the high amounts of estrogen it contains. However, there is no real evidence showing it has messed up girls reproductive systems. In fact there are cultures who eat this as a main staple in their diet. I heard the Japanese for one.
As well, there is that commune of hippies in Tennesse who had a population of 3,000 at one point, who had set up food production on an industrial size basis to feed each other, all based on the Vegan diet, no milk, mainly everything came from soymilk. And I never heard that this interferred with “baby having” later in life.
