Trauma-focused psychotherapies for infants, toddlers, and preschoolers comprise a unique subset of child trauma interventions. Given the developmental age range in question, certain characteristics of these therapies differ significantly from those for older children. This study reviews evidence-based, trauma-focused treatments for young children and their caregivers, followed by evidence-based treatments for trauma-vulnerable families with very young children that do not target trauma directly but rather reinforce attachment-related protective factors such as parental sensitivity and reflective functioning. Directions for further research are discussed.
