The concept of soy formula being bad is new to me. I thaught this is
preferrable to formula based on cows' milk if we have to use formula,
because a lower allergy incidence. This is used very frequently here, for
any suspicion of cows' milk formula allergy (fussy baby, spitting up etc.),
or as the preferred suplement to breastmilk (for whatever reason).

Could someone post any references about this?

What would you use as the preferred supplement (if mother insists, or if
medically necessary)?

Thanks,
