This paper comprises a collection of illustrations, along with background information, analysis, and commentary, from “baby books”—advice books published in the United States for a parent audience from the 1890s to the 1980s. These publications, and especially their drawings and photos, provide a window on past child rearing practices and beliefs. The paper provides historical background on parenting behaviors such as toilet training and infant feeding, then traces changes over time through drawings and photos that appeared in parenting advice publications. These publications grew in popularity as changing work and family structures removed traditional sources of information for parents, and scientific information and expert guidance took their place. Publications from a variety of sources, but especially the U.S. Children’s Bureau, are explored. A finding of note is that images of babies and their families, which in earlier publications were entirely white and middle class, became more diverse over time. The author concludes that published parental advice from professionals made for a fascinating study, was ideologically driven, and often lacked a basis in empirical scientific knowledge of child development, and therefore asserts that parents may regard such advice conditionally.
