Children need to swing and then jump off the swing. They need to explore forests and junkyards in search of novelty and adventure. They need to shriek with their friends while watching a horror movie or riding a roller coaster. In the process they develop a broad set of competences, including the ability to judge risk for themselves, take appropriate action when faced with risks, and learn that when things go wrong, even if they get hurt, they can usually handle it without calling in an adult.
