Teenagers should spend no more than two hours on the internet each day, doctors warned as they advised parents to remove laptops and gadgets from their children’s bedrooms.
Many mothers and fathers remain “clueless” about the impact excessive media exposure can have on their children and need to “get with it”, it was suggested.
Dr Victor Strasburger of the University of New Mexico, the lead author of a new policy document from the American Academy of Pediatrics, claimed that all 14-year-old boys with an internet connection in their bedroom would be looking at pornography online.
Under the advice, a two-hour limit should be imposed on using the internet for entertainment, including Facebook, Twitter, television and films.
The recommendation came as a poll suggested almost two in five babies have used a mobile phone or tablet computer before they can even string a sentence together.
