What safety experts suggest, by age
Wherever you live, the Canada Safety Council’s guide is a useful yardstick. It suggests not leaving a child alone before 10, and then building up slowly:
| Age | How long, at most |
|---|---|
| Under 10 | Not alone |
| 10–12 | Up to two hours, with a responsible adult nearby |
| 13–14 | Up to five hours, with an adult reachable by phone |
| 15–16 | A whole day, with a parent reachable by phone |
Age is only half of it. A child who wants to, follows rules when you’re out, stays calm when something goes wrong and can always reach an adult is ready sooner than one who isn’t. Our guide to how old a child should be to stay home alone has a readiness checklist and how to set up the after-school routine.
The days that don’t fit the routine
Home alone after school works until it doesn’t: a sore throat, an early dismissal, practice across town at 4:30. Those are the days nobody thinks about cover until 2:45. In Kid Pickup you post the pickup, someone in your circle taps I’ll do it, and if nobody has it the app sends you a nudge with time to sort it out.
