Children and families who have been separated at our southern border have faced significant trauma. The more than 2,300 detained children need to be reunited with their parents immediately. As professionals with many years of shared experience working with children and families, supporting their health and well-being is our core mission. The experiences that we have seen depicted in vivid images and horrible headlines run counter to everything we know from decades of developmental research about what children need to thrive. From our research and experience supporting children, we know that being forcibly separated from parents is, in fact, among the most negative experiences a child can have.
