“So yall… This is just cuckoo awesome — I read an article from a medical journal not too long ago about how Mom’s milk changes to tailor baby’s needs in more ways than just caloric intake.. So this doctor discusses that when a baby nurses, it creates a vacuum in which the infant’s saliva sneaks into the mother’s nipple.
There, it is believed that mammary gland receptors interpret the “baby spit backwash” for bacteria and viruses and, if they detect something amiss (i.e., the baby is sick or fighting off an infection), Mom’s body will actually change the milk’s immunological composition, tailoring it to the baby’s particular pathogens by producing customized antibodies.”
