The truth is, there's no foolproof way to "control" them and prevent them from doing what we don't want them to do, especially when we're not around. But this isn't just a problem with screens, is it? I mean, there are some parental control apps and devices to reduce this risk, but they're not infallible. A good approach is to act as we have in the past (for example, when they first start going out alone): we need to make sure they understand the risks, that they have the tools to manage them, and once that's done, we can start with trial and error. If the trial goes well, we give them a little more autonomy; if not, we take a step back and review what didn't work, without blaming them for the mistake.

Specifically, it is often helpful to reduce the risk of doing other activities while doing homework (leaving the mobile phone somewhere else, not having the television on, etc.), set a time to do homework and then leave time to use screens for leisure, supervise or accompany these moments and talk with our sons and daughters so that together we can see what works and what doesn't.
