Despite trauma being widespread and detrimental to the well-being of infants, toddlers, and preschoolers, few early care and education (ECE) programs and state systems are prepared to offer care that is "trauma-informed"--with all adults able to recognize and respond to the impact of trauma on young children, and to infuse trauma awareness, knowledge, and skills into program culture, practices, and policies. This executive summary describes early childhood trauma and its effects, offers promising strategies for ECE programs and systems to help young children who have experienced trauma, and presents recommendations for state policymakers and other stakeholders looking to support trauma-informed ECE for this vulnerable group.
