In 1931 the United States Children's Bureau asserted that "nothing short of really healthy children should satisfy parents." This thesis examines how literature published by the Children's Bureau from 1913 to 1933 shaped perceptions of motherhood and of maternal control over the body. As the bureau taught mothers how to care for their children, it also taught them that by following bureau advice, mothers could shape the bodies of their children to adhere to normative body standards. The research considers the relationship between mothers, the state, and the physical body. This thesis is divided into chapters about prenatal care and maternal marking; infant care and maternal policing; and child care and maternal control.
