The statistics of children and families experiencing military life and affected by deployment are astounding. Many children who have an uncle, aunt, brother, or other family member serving in the military live near a military duty station, but others live far from other military families. Caregivers and teachers of young children share a common goal of providing safe, nurturing, learning environments for children. They ensure this by continually educating themselves about the needs of children and the best practices for development and learning. Understanding military deployment and children's behaviors and needs during this time is no different. Caregivers and teachers must learn what these families and children are experiencing and how they can support them so that they can continue to meet all of their needs and support their positive growth and development as they are challenged by this experience. This article discusses the cycle of deployment, which is divided into five stages: (1) pre-deployment; (2) deployment; (3) sustainment; (4) re-deployment; and (5) post-deployment/reunion. The characteristics of (and children's needs during) each cycle are described.
