Science is only beginning to understand the interactions between a mother and her kid during pregnancy and after birth. It is true that the so-called “mommy” brain exists. The mother’s brain adapts because of neuronal and hormonal changes throughout pregnancy and after birth “to enhance the mother’s ability to care for her infant,” according to the statement. The mother’s brain undergoes remodelling due to hormones and other substances, with some regions growing larger than others. Some of the regions impacted are nesting and defending the young, two control behaviours. The development of “maternal behaviour,” which is characterised by “caring and loving actions typically associated with caring for and raising the young,” is aided by many of the changes.
