Through the mother’s nipple in milk ducts after each sip your baby enters a little mixture of milk and its saliva, thanks to the creation of a vacuum and negative pressure, says evolutionary biologist Katie Hynde.
Babies breastfed mother’s milk, but liquid does not go in one direction only. Through the mother’s nipple in milk ducts after each sip your baby enters a little mixture of milk and its saliva, thanks to the creation of a vacuum and negative pressure, explains on her blog, Katie Hynde, an evolutionary biologist and expert on the impact of mother’s milk to the child’s development. And that saliva says mother’s immune system what the baby at the time required! Thus, if the baby is ill, in milk increases the amount of certain immune factors.
Namely, in the saliva of sick babies are pathogens from the baby’s nose and throat. So that the mother’s immune system begins to respond to pathogens which are now found in the mother’s body. Baby rely on the protection of the mother’s immune system because its still in its infancy – because breast milk is not only food, but also medicine.
But that’s not all – when breast milk mixed with baby’s saliva comes to a chemical reaction in which hydrogen peroxide is formed, which prevents the growth of dangerous pathogenic bacteria such as golden staph and salmonella, while encouraging the development of beneficial bacteria.
This is another example that shows that breastfeeding is a complex dynamic biological process, not merely feeding the child, concludes Katie Hynde.
