The government is considering introducing tougher online safety measures to limit the amount of time children can spend on social media, the BBC understands.
Proposals include a two-hour cap on the use of individual social media apps and a 22:00 curfew, as first reported by the Sunday People and the Mirror.
Appearing on the BBC's Sunday with Laura Kuenssberg programme, Technology Secretary Peter Kyle said he was looking at the "addictive nature of some of the apps and smartphones", when asked whether time limits would be considered.
But an online safety campaigner has accused the government of delaying bringing in new laws to protect children.
Ian Russell, whose daughter, Molly, took her own life at 14 after seeing harmful content online, said: "Every day the government has delayed bringing in tougher online safety laws we've seen more young lives lost and damaged because of weak regulation and inaction by big tech."
