The trauma of separation lingers long after children are reunited with parents

Long after the wailing and tears, the trauma of separation can linger in children's minds, even after they are reunited with their parents, experts say.

On Wednesday, under pressure from around the globe and his own party, President Trump signed an executive order to keep migrant families together. For some, the crisis may now seem resolved. But experts warn that for many of those children, the psychological damage of their separation will require treatment by mental health professionals — services they are extremely unlikely to receive because of U.S. government policies for undocumented migrants.
