Writing for The New York Times last year, Michael Erard said there’s a particular book he likes to give friends who are expecting their first child. He calls it “the only book that new parents will ever need.” It’s titled The Anthropology of Childhood: Cherubs, Chattel, Changelings, and its author, anthropologist David Lancy, has far-reaching and sometimes controversial opinions about the way we raise children in Western nations. His goal, he says, is to offer a correction to the view that “sees children only as precious, innocent, and preternaturally cute.”
