Pat Bull and others, The New Zealand study said that a soy-formula fed baby gets 100 times the amount of estrogen than a BF baby? The equivalent of several contraceptive pills? What kind of major problems could this cause in the future of a child? Soy formulas have always bothered me and 25% of formula fed infants are on it! The components are too far removed from breast milk to even be comparable. An IQ study on these children would be interesting.... I predict that soy formula might very well be subject of the first lawsuit against formula companies. What do you think? Pam Wiggins, IBCLC, Franklin, VA
