In modern pediatric practice, gender matters. From the pink-and-blue striped receiving blankets used to swaddle newborns, to the development of sex-specific nutrition plans based on societal expectations of the stature of children, a gendered culture permeates pediatrics and children's health throughout the twentieth and early twenty-first centuries. This book provides a look at how gender has served as one of the frameworks for pediatric care in the U.S. since the specialty's inception. Pink and Blue deploys gender-often in concert with class and race-as the central critical lens for understanding the function of pediatrics as a cultural and social project in modern U.S. history.
