The mother-child bond is critical to healthy development. Love between the two is even biochemically hard-wired. We need to take note as society moves in a direction that assumes that so long as children's basic needs are met all is well. It isn't.

Scientific studies conclude something mothers everywhere have always intuitively known - that the unique love they have for their offspring is vitally important to their development. A mother's love and nurturing even directly impacts the biological development of the child's brain and central nervous system. In effect, mother and child are "hard-wired" for mutual love. The brain is like a template designed to await molding by its early environment. One researcher even wrote that hugs and kisses during the early critical periods assist in making neurons grow and connect properly with other neurons.

Throughout childhood, warm human love and touch generate an internal release of addicting and pleasurable opiates. Even teenagers (who may act as if they don't need the parents at all) must receive ongoing neural synchrony - love - from the parents. The brain and heart appear literally designed for love, with happiness and even health depending on it.

The pituitary hormone, oxytocin, is present during all loving acts but most especially at birth where it serves to stimulate uterine contractions, and during nursing for the milk ejection reflex. It, along with the nursing hormone, prolactin, help create that intense feeling of love shared by mother and child. Endorphins are physiological chemicals that are also released in both the mother and child during loving contact. They create a feel-good high for both and thus play a critical role in encouraging affection and dependency.

When bonding fails, it is theorized that the absence of these pleasure chemicals can leave a void, making such children especially susceptible to drugs that can also release such pleasure chemicals. The stress hormone cortisol is also released when touch and love are lacking. Sensory deprivation in mother-absent children - a form of stress that stimulates the release of cortisol - can increase susceptibility to abnormalities such as depression, violence, substance abuse, and even impaired immune response.
