Our children are in constant danger from — to quote Lenore Skenazy’s list — “kidnapping, germs, grades, flashers, frustration, failure, baby snatchers, bugs, bullies, men, sleepovers and/or the perils of a non-organic grape.” Or so a small army of experts and government policymakers keep insisting. School authorities punish kids for hugging a friend, pointing a finger as a pretend gun, or starting a game of tag on the playground. Congress bans starter bikes on the chance that some 12-year-old might chew on a brass valve. Police arrest parents for leaving a sleepy kid alone in the back seat of a car for a few minutes. Yet overprotectiveness creates perils of its own. It robs kids not only of fun and sociability but of the joy of learning independence and adult skills, whether it be walking a city street by themselves or using a knife to cut their own sandwich. No one has written more provocatively about these issues than Lenore Skenazy, a journalist with the former New York Sun who now contributes frequently to the Wall Street Journal and runs the popular Free-Range Kids website where she promotes ideas like “Take Your Kids to the Park and Leave Them There Day.” Her hilarious and entertaining talks have charmed audiences from Microsoft headquarters to the Sydney Opera House. Please join her and Cato’s Walter Olson for a discussion of helicopter parenting and its unfortunate policy cousin, helicopter governance.
