Nancy's guest this month is her sister (!) Dr. Susan Linn, whose new book, The Case for Make Believe, encourages parents to turn off the television, hide the computer games, and send their kids out to play. In an era when toys come from television and media companies sell videos as brain-builders for babies, Linn lays out the links between play, creativity, and health, showing us how and why to preserve space for make-believe in children's lives. Dr. Linn is Associate Director of the Media Center at Judge Baker Children's Center and Instructor in Psychiatry at Harvard Medical School. She is also co-founder and director of the coalition Campaign for a Commercial-Free Childhood. Dr. Linn lives in Brookline, Massachusetts, with her husband and daughter.
