Screen Time Rules That Stick: How to Write a Family Agreement
Sep 28, 2026
In short
Rules made at the end of a bad evening don't last because a child reads them as an emotional reaction. Write down why first, then a one sentence rule your child could repeat back, show them a draft, and expect two weeks of testing before it settles.
Most screen rules get made at the end of a bad evening. Somebody has had enough, a rule gets announced, everyone goes to bed, and two weeks later it has quietly stopped existing. When parents tell me a rule didn't stick, that is nearly always how it got made, and it isn't a discipline failure. A rule introduced in a moment of frustration is experienced by a child as an emotional reaction rather than a stable expectation, and children treat emotional reactions as temporary. They're usually right.
Start with why, not with what
Try this first
Before you decide on any limit, write down what you're protecting, not what you're taking away. It might be so your child sleeps properly and school isn't miserable, so your evenings feel like you're actually together, or so there's time for the things they like doing that aren't this.
This isn't a presentation trick. When the rule is about protecting sleep, you know what to do when a real exception comes up, because you can ask whether the exception threatens sleep. When the rule is only a number, every exception is a negotiation from scratch, and you'll lose most of them because you're tired. It changes how your child hears it too, because a limit that's clearly connected to something they care about can be argued with, while a limit that arrived because you were annoyed has nothing behind it except your willingness to keep enforcing it.
Then write the what, with no vagueness in it
The rule has to be specific enough that your child could repeat it back to you, and if you can't write it in one sentence, it isn't finished. Some examples that pass that test:
- All devices are off and charging in the kitchen from 9pm on school nights.
- Screens after homework is finished and checked, not before.
- Thirty minutes of TV after school, then homework, then the Xbox if there's time.
- Two hours a day on personal devices, and no social media apps.
The words that cause trouble are the soft ones, such as "not too long," "a reasonable amount," or "when you've done enough homework." Every one of those is an invitation to negotiate, and you'll be doing the negotiating at seven in the evening when you have the least capacity for it. The word "checked" in the second example needs deciding in advance as well, because otherwise you'll end up arguing about whether the homework is finished instead of about the screen.
Bring your child into it
I talk about this with families as cooperation rather than control, and the difference between the two is worth quite a lot of effort to get. Show your child a draft at a calm moment, several days before it starts, tell them you want their view and give them a day to think about it. You don't have to accept everything they suggest, and you shouldn't pretend you will, but if one or two of their points make it into the final version, the whole thing changes character, because a child who got something into the plan treats it as their plan. Some families find it easier to write it as a short letter than to have the conversation cold. It lets you say the good part first, which almost always gets lost out loud, and it's less confrontational than standing in a doorway.
Dear [name],
We're really proud of you at the moment. You're working hard at school and you've got a good group of friends, and we want all of that to keep going.
We've been thinking about what matters to us as a family and where screens fit into it. We think you manage pretty well. There are still a couple of things we want to change, mainly to protect your sleep, and because we want more time together in the evenings.
Here's what we're thinking: [the specific rule].
Think it over and let's talk tomorrow. We're open to adjusting some of it. This works better if we sort it out together.
Love, [names]
Your child doesn't have to like the rule. They do need to be able to say back to you what it is and why it exists.
A worked example, for a ten year old
Why: so you sleep properly, and so we get some time together that isn't everyone on a device.
What:
- Tablet and TV after school once homework is done and checked by an adult.
- Screens off at 7:30pm every school night.
- All devices charge in the kitchen overnight, including the adults' phones.
- Weekends are looser, and the 7:30 charging time still applies.
- Fridays we watch something together, chosen by whoever's turn it is.
When it goes wrong: the device goes to the charging spot and the rule carries on tomorrow. No extra penalty and no long conversation about it.
That last line matters more than it looks. Decide what happens when the rule is broken before it gets broken, because otherwise you'll improvise something harsh at nine in the evening and then have to either enforce it or back down, and both are bad.
Pick one or two changes, not five
The most common way I see a good plan die is that a parent does the thinking, sees the whole problem clearly, and introduces five new rules on a Monday. Nobody can be consistent with five things at once, and consistency is what's doing the work here, so pick the change that will make the biggest difference or the one that will be easiest to get stable, and leave the rest alone until the first one has held for a few weeks.
The two weeks that decide it
Week one is the worst, with more testing, more requests for exceptions, and probably one evening that feels like proof this was a mistake. Resistance at that stage tells you your child has noticed the change, which isn't the same thing as the change being wrong. Week two is easier, because protests get shorter once they aren't producing anything, and by week three it's mostly settled, as long as the rule has been the same every single day. If it slipped twice, expect the testing to continue, because from your child's side the boundary is still uncertain and worth checking. What I see predicting success isn't how strict the rule is, it's how predictable it is, along with following through calmly, and adding new consequences in the middle of an argument makes everything worse.
When it points to something bigger
If every attempt at a limit ends in a crisis, if your child can't enjoy anything offline, or if you're seeing low mood, withdrawal or anxiety alongside the conflict, an agreement isn't the right tool on its own. Talk to your pediatrician or a child mental health professional.

The Screen Balance Program walks you through the whole sequence: working out which change to make first for your specific child, writing the agreement, and holding it through the two weeks that decide whether it lasts.
