According to the World Health Organization*, it is the most effective way to ensure the health and survival of an infant.
And the composition of breast milk makes it precious and ideal for the baby. It is therefore no coincidence that the mother's milk of the first days, the so-called "colostrum", is often characterized as the "first vaccine", due to the high percentage of immunoglobulins it contains. Its high-value ingredients include proteins, sodium, leukocytes, lactoferrin, chlorine, epidermal growth factor and carotene.
However, beyond its biological benefits, breastfeeding is invaluable as it strengthens the emotional bond between mother and infant, creating a sense of security for the baby. It is characteristic that, during breastfeeding, oxytocin, the so-called "hormone of love", is produced, while prolactin also contributes to the creation of a feeling of calmness.
As noted by P.O.Y., breast milk contains antibodies that protect the baby against common childhood diseases,while at the same time providing all the energy and nutrients that infants need in the first months of their lives.
In fact, children who were breastfed as infants are shown to have higher intelligence test scores than other children, are less likely to become overweight and have a lower risk of developing diabetes.
As for mothers, women who have breastfed their children appear to have a reduced risk of breast and ovarian cancer.
According to the P.O.Y., infants should be exclusively breastfed for at least the first six months of their lives in order to ensure optimal growth and health. Then, from six months onwards, she suggests that babies start receiving complementary foods alongside breast milk.
