MOTHER BRAIN

How parenting affects body and mind.

Conaboy, a journalist specializing in health issues, makes an engaging book debut with an informative, well-researched look at the physical and psychological changes caused by engaging in “the life-supporting practice of mothering.” Drawing on interviews with parents, scientists, and medical practitioners; examining abundant research; and reflecting on her own experiences as the mother of two sons, the author depicts motherhood as “a distinct developmental stage with long-lasting effects, in which each of the body’s systems thought to regulate social behavior, emotion, and immune responses” are dramatically affected. Noting the dearth of scientific studies about parents who are not “straight, cisgender people who share DNA with their child,” Conaboy focuses largely on birth mothers while also reporting on the experiences of fathers and other relatives involved in caregiving. In a historical and cultural overview of assumptions about motherhood, she underscores the social, political, and religious forces that gave rise to “the fallacy of the maternal instinct,” which has left some women feeling inadequate and guilty. She roundly debunks this notion, taken as scientific fact by lawmakers who want to limit reproductive rights and maternity benefits by arguing that motherhood is women’s destiny and that mothers are innately constituted as caregivers. Conaboy shares research in neurobiology and endocrinology that has revealed complex ways that pregnancy, birth, and caregiving reorganize the brain, “altering the neural feedback loops that dictate how we react to the world around us, how we read and respond to other people, and how we regulate our own emotions.” These changes occur, in varying degrees, in both men and women. The author deftly translates scientific studies—by neurobiologists, anthropologists, primatologists, psychologists, and endocrinologists, among others—into accessible prose that speaks to needs and anxieties that many parents share. Adapting to motherhood, she asserts, is “a bodily challenge and a logistical challenge” that lasts a lifetime.

Useful, well-informed encouragement for new and prospective parents.
