The author describes the physical and emotional effects of chemical addiction in families on infants and toddlers and suggests that service providers take into account both chemical addictions research and theoretical knowledge of the importance of early parent-infant relationships. Describing a model that incorporates interagency and interdisciplinary teams to coordinate services, the author explains how these teams can work to provide comprehensive treatment interventions that are responsive to the unique needs of infants, toddlers, and families. In order to break the cycle of intergenerational family chemical addiction, treatment programs for pregnant women and families with young children should ensure that children receive necessary early intervention services, offer support groups and treatment to extended family members, and provide support for foster parents or other primary caregivers when children are in out-of-home placements.
