The long wars in Afghanistan and Iraq have presented unique challenges to military-connected families with very young children, yet few evidence-based services are available to support these families through deployment and reintegration. Although many military families have shown remarkable resilience throughout the intense demands of the wars, very young children (from birth through 5 years old) and service member parents' relationships with these children are particularly vulnerable in the face of deployment. Interventions targeted to the post-deployment period can assist families in managing the challenges of reintegration for parents and young children. The authors describe the process of developing and testing a culturally responsive home-based reintegration program for service members, their partners, and their very young children. Composite case examples are presented to illustrate the major concerns of military families and to highlight program elements aimed at enhancing parental reflective functioning and strengthening parent-child relationships.
