A safety organisation in the Netherlands is campaigning to encourage parents to let children play more dangerously.
Dutch children are the happiest in the developed world according to Unicef, but the national safety body VeiligheidNL believes they are being "pampered".
It has launched a campaign called "Risky Play", saying children should be encouraged to play with pocketknives, climb trees and light fires - with appropriate supervision.
It tells parents and schools that children are not learning to manage risk, even though solo child cyclists are a regular sight on the school run.
Project leader Judith Kuiper said: "This initiative has a wider goal: it aims at what we call 'risk competence', so children become more independent and better at protecting themselves."
