Today: the lighter and darker sides of childhood. Host Maria Hinojosa speaks to K, who works with detained children who came to the United States without an adult. We examine Latino studies, or lack thereof. We examine the uneven impact of dress code policies. We hear a children’s book read by author Yuyi Morales and about the life of NYC librarian Pura Belpre. Teachers in California write a book in the indigenous Mexican language of Mixteco. And from the mouths of babes comes this week’s sabiduría.
