Despite a call for action to address the needs of infants and toddlers in the child welfare system, they continue to be overrepresented in allegations of abuse and neglect, substantiated cases of maltreatment, and entry into foster care. Given the ongoing unique needs for infants and toddlers involved with child protective services, the rising proportion of this age group with substantiated reports, and the importance of this developmental period, practitioners involved with maltreatment prevention and promotion of child and family well-being are in an important position to provide the necessary support for infants, toddlers, and families in need. Therefore, the goals of this presentation are first, to provide the necessary background information to understand the developmental impact of maltreatment on infants and toddlers; and second, to provide information on available resources and practice recommendations that practitioners can use to support infants, toddlers, and their families.
