What is screen time doing to children?

This group, based in Britain, is not the only one worried about children’s screen time. Last month the state of Florida passed a law banning social media for under-14s. Britain’s government is reportedly considering a ban on mobile-phone sales to under-16s. The concerns are summed up by a recent book by Jonathan Haidt, “The Anxious Generation”, which argues that smartphones, and especially the social networks accessed through them, are causing a malign “rewiring of childhood”.
