The study of infant, child, and adolescent remains (nonadult remains) is a topic of growing interest within the fields of archaeology and bioarchaeology. Many published volumes and articles delve into the experiences of childhood and what these small remains may tell us about life, more broadly, in the past. For those interested in exploring infant and child remains, it is an exciting period as more methods and approaches are constantly being incorporated into the archaeological toolkit. This Element introduces the reader to the topic and to common methodological approaches used to consider nonadult remains from archaeological contexts. With this toolkit in hand, readers will be able to begin their own explorations and analyses of nonadult human remains within archaeological contexts.
