Sure, in the bottle feeding society, where formula is equal to
breastmilk, you lose a little bit of something in the breastmilk and
all of a sudden formula is better.  O tempora o mores.  It's the same
as: as soon as you get micrograms of some drug in the milk,
breastfeeding loses all its previous benefits.  We have sooo far to go
still.
