Dr Aric Sigman - who is also a child health expert - has made a raft of suggestions for children's screen consumption including delaying the age children start using screens to at least three.
Children aged between three and seven should be limited to half-an-hour to an hour of screen time each day, he said.
Those aged seven to 12 should spend just one hour in front of screens.
Children aged 12 to 15 should have a maximum of 1.5 hours in front of screens and those aged 16 and over should spend just two hours, he recommends.
