Research shows that not all hours spent glued to a screen are created equal, so I’m actively encouraging nutritional content such as Minecraft

I’m not particularly into banning things in my house, partly out of laziness – enforcement creates conflict, or at least a need for me to get up and do something – and partly out of a dim conviction that the more rule-bound the child, the greater the meltdowns. The kid not allowed snacks between meals goes mad at houses with an open-fridge policy. Inflexible bedtimes create inflexible children. News blackouts designed to preserve the innocence of a child can make the world seem more not less frightening, and so on.

The obvious exception to all this is tech, which takes away all of our abilities to self-regulate. Until recently, I imagined there was no amount of slack-jawed screen time that would exhaust my children’s appetite for it. This has turned out to be wrong: one child, off sick a few weeks ago, actually looked up bleary-eyed from her iPad after two days of constant usage and expressed a desire to go back to school. More generally, however, they will want more time on it than I think healthy, even as I use the time bought by their screen addiction to feed my own.
