I always found formula to be unnatural and disturbing even before I read a label. Babies fed formula have black, tarry, nasty shits, nothing like breast-fed babies.
Back in ye olden days, there were wet nurses (or in rural areas, goats).
Now we pump them full of highly processed corn with pesticides, highly processed soy with pesticides, and highly processed seed oils, supplemented with biologically unavailable vitamins.
Mmmmmm, Yuuum!
