Rates of family homelessness continue to reach unprecedented levels. As many as two million young children experience family homelessness each year, with an estimated one in 10 younger than one year old.

This presents a severely limited understanding of homeless infants’ and toddlers’ experiences, with substantial gaps remaining. This review documents the scant existing literature on infant and toddler development within the context of homelessness at both the individual and family-system levels, and proposes next steps for research, practice, and policy.
