First I am not vegan, in fact I love meat. That said I have to point out some errors, in some of the post here. I happen to know for a fact that there have been Soy formulas since 1975. When I was a baby my body reject animal milk (including my mothers breast milk), and I was prescribed, by a doctor, a soy formula as an infant.

Health effects: Of my 11 brothers and sisters I was the only one not breast feed: some are overweight, I and most are not; I and few others have unbelievable immunes systems, most have okay or less; I am the tallest of my brothers and sisters, and one of the smartest.
So where are my adverse health effects from being deprived animal milk? There are none. Sorry I am healthy as a horse with no diseases, allergies, or any other ailments that I am aware of.

Basically, I have to disagree (from looking at myself) with anyone that says a vegan diet for infants is unhealthy. Vegetarian and non-vegetarian parents malnourish there children every day because of ignorance. I have a neighbor who thinks potato chips, hotdogs, and coke are part of a healthy diet. Consult a doctor to ensure your child gets all the nutrients it needs regardless of your food preferences.
