Familiar with the Environment

'Children are not being allowed many of the freedoms that were taken for granted when we were children,' said Adrian Voce, director of Play England. 'They are not enjoying the opportunities to play outside that most people would have thought of as normal when they were growing up.'

Voce argued that it was becoming a 'social norm' for younger children to be allowed out only when accompanied by an adult. 'Logistically that is very difficult for parents to manage because of the time pressures on normal family life,' he said. 'If you don't want your children to play out alone and you have not got the time to take them out then they will spend more time on the computer.'

Voce pointed out how irrational some of these decisions were. Last year, almost three times as many children were admitted to hospital after falling out of bed as those who had fallen from a tree.
