Maternity leave and infant brain development

It is not until about eight weeks of age that an infant has a fully developed capacity for mutual gaze.

Then a baby looks directly into his mother’s eyes, while she, in turn, reflects back this loving gaze, cooing softly in response to her baby’s earliest communication. When a mother looks at a baby in a way that communicates with him, not with words but with feelings, “I understand you,” he begins to recognize himself, both physically and psychologically. He begins to be able to regulate his feelings. This mutual gaze, literally and figuratively being “seen,” actually facilitates the development of the baby’s brain.

The Massachusetts Supreme Judicial Court now has proposed to interrupt this newly emerging dance of co-regulation by ruling this week that woman workers are entitled to only eight weeks of maternity leave. This ruling applies only to women whose maternity falls under state law, and differs from the wiser federal Family and Medical Leave Act of 1993 which provides up to 12 weeks of unpaid leave and job protection.

Research at the interface of neuroscience and infant development is offering great insight into how mutual gaze actually grows the brain. Our knowledge about early brain development is derived from a combination of detailed video observations of mother-infant interaction and studies of the brain known as functional MRI. These imaging studies can actually see which parts of the brain are responsible for what behaviors. This research has shown that healthy wiring of the brain is contingent on attuned responses of caregivers. This attunement is not only in gaze but in touch, sound of voice and facial expressiveness.

Certainly a mother who works full time is well able to facilitate her child’s healthy development if she is receiving appropriate support. But even under the best of circumstances, returning to work means that a mother will be stressed. Offering her the option for a full three months of what D.W. Winnicott, pediatrician turned psychoanalyst, referred to as “primary maternal preoccupation” seems an important and wise investment in the next generation.
