The 1946 publication of Dr. Benjamin Spock's Baby and Child Care signaled the pervasive influence of expert 'medicalized motherhood' in mid-twentieth-century America. Throughout the previous two decades, pediatricians and women's magazines alike advised mothers of the importance of physicians' guidance for the everyday care of their children, and Spock's book popularized this advice, particularly among white, middle-class women. When Jacquelyn S. Litt interviewed African-American and Jewish women who raised their children in the 1930s and 1940s, she found that these women responded to experts' advice in ways uniquely shaped by their ethnicity, race, and class. Litt's book is enriched with many narratives from the mothers themselves. Both the women's voices and her acute sociological research bring to light how medicalized motherhood, while not the single cause of difference and inequality among the women, was a site where they were produced.
