For David Krieger’s kids in south Florida, screens were a weekend treat. Now, every day is iPad-appropriate.

The family’s schedule tries to cap the fun time on screens for the two kids to an hour between their educational activities, both also on electronic displays: a Zoom reading class, and an online drawing session. But the limit never sticks. With two working parents, "it is a necessity,” Krieger says.

As stay-in-place orders to contain the spread of the coronavirus globally keep 1.5 billion school children home, restricted screen time is becoming a thing of the past. Across the world, from the Krieger kids to Mila, 9, in Paris, who loves attending classes on Zoom, and Ruby, 5, in London, who’s now a whiz at Minecraft, children are spending more time on their screens than ever before.
