dear mira and all, yes, soy formula is bad in its own special way. i of course don't remember an actual reference for where i read this (not lactation related, but agriculture related), but soybeans are one of the crops grown with the highest levels of pesticides and chemical fertilizers (tomatoes and cotton being two others). since there is no organic soy formula, i would count this as yet another drawback of this stuff. as well as making babies really STINK. carol b.
