When stopping is the hard part

The short version, first

Three things are true about stopping one thing to switch to another:

1. The struggle isn't about the screen, or the park, or dinner. It's about the switch itself. Stopping one thing and starting another is a specific, effortful job for the brain — and it's hard in a way that has nothing to do with how much they love you or how good a parent you are.
2. "They knew it was coming" doesn't make it easier — sometimes it makes it harder. A brain that's deep in something it enjoys isn't ignoring you. It's somewhere that's genuinely hard to pull away from on cue, and the better the thing they're in, the harder it is to leave.
3. There's no gadget that fixes this. There's a way of handling the moment — the same switch, done the same way — that gets smoother as it wears in. And your own calm is part of how it goes.

That's the short version. Here's what's underneath it.
