This essay focuses on the many “baby books” currently available that consist mainly of photographs of of other images of babies, and considers how these images might represent replications or restagings of the mirror stage and function as versions of the Ideal-I for their implied baby viewers. As images of actual children, the photographs in these books represent what most adult viewers take to be the most realistic representations of babyhood possible––the way babies actually look, which, in the context of Lacan’s Ideal-I, might better be understood as the way babies are actually supposed to look as currently understood. In terms of conventional adult assumptions about how baby viewers might look at and understand these images in relation to themselves, these images quite literally restage the mirror stage––show the baby an image of a baby to identify with and see as what it ought to be itself. By considering the implications of a number of photographs and other images of of babies in baby books, the essay explores what these books tell their implied baby reader/viewers about what it means to be a baby, and about what is the right kind of baby to be.
