Mobiles warning for mums-to-be: Using phone while pregnant 'can lead to behavioural problems in children'
Pregnant women who regularly use mobile phones could increase the risk of their children behaving badly, claims a startling survey.
If their offspring then start using the devices at an early age, the chance of problems climbs to 50 per cent, according to researchers.
They found those exposed to mobile phones in the womb had a 30 per cent rise in behavioural difficulties at the age of seven. But those exposed before birth and in their childhood, were 50 per cent more likely to have behavioural problems than those exposed to neither.
Children who used mobiles, but were not exposed in the womb, were 20 per cent more likely to display abnormal behaviour.
