Children younger than three are overrepresented in substantiated cases of abuse and neglect. As with all maltreated children, infant and toddler victims of abuse and neglect are disproportionately affected by developmental delays. Over the past 20 years, child development research has demonstrated the importance of the first three years of life on subsequent learning, behavior, and social development. To ensure intervention during this critical stage of life, 2003 amendments to the Child Abuse Prevention and Treatment Act (CAPTA) require child welfare programs to refer all child victims of abuse and neglect younger than three to local early childhood intervention programs. These children receive an evaluation, and if they have developmental delays, they are referred for intervention. This article examines implementation challenges for this legislation with regard to parental consent to and participation in early childhood intervention. Practical guidance for child welfare and early childhood intervention professionals is provided.
