1 in 4 fathers rely on tablets to play with their children Allan Johnston, one of the team behind Justin's World and the creator of CBeebies star Mr Tumble, said it was important to offer children "a balanced diet." "As a Dad myself I can see why the tablet is so popular," he said. The only thing I would say is, like anything in life, it's all about offering your child a balanced diet. So although tablets definitely have a positive role to play in modern family life, there should also be times when you revert to more traditional forms of social interaction. The survey questioned 1,000 parents who have children between the ages of two and six. It comes after a cyber security firm found that tablets designed for children often have little or no security and are vulnerable to hacking. The NCC Group assessed two children's tablets which are likely to be on many Christmas lists and found children's security and privacy is at risk. "The results of this analysis showed that little to no security and privacy engineering happens in the device marked aimed at children, putting theirs as well as your security and privacy at risk," the security experts warned.
