Separating children from their caregivers, holding them in detention centers, and subjecting them to prolonged institutionalization and neglect is a critical issue that transcends political ideology and partisanship and speaks to the heart of what the mission of the Center on the Developing Child is all about. Here, the Center has collected resources addressing this issue for members of the press, policymakers, and anyone who wants to understand what the science of child development tells us about the harm that occurs as a result of separation in institutional care.
