Exterogestation in human babies explains the connection between the developing infant's nervous system and the mother's regulation through closeness.
As human infants are born relatively underdeveloped, they rely on the external environment, including the presence of their caregivers, to fulfill their needs for warmth, safety, and nourishment. The prolonged period of postnatal development allows for essential nurturing and bonding, creating a symbiotic relationship between the baby and the mother. When the baby is held close and experiences physical contact, a cascade of neurobiological responses is triggered in both the baby and the mother.
The baby's heart rate, breathing, and stress levels synchronize with those of the mother, promoting a sense of security and comfort. This regulation through closeness not only enhances the baby's emotional well-being but also contributes to the maturation of their nervous system and healthy brain development.
