Talking to Your Child About Device Rules: Three Conversations by Age

The setup takes twenty minutes. The conversation is what decides whether the rule lasts a fortnight or a few years, and most parents are given no help with it at all.

By Guardino Team · Guardino Technologies

Every guide to parental controls explains how to configure the software. Almost none explain what to say, which is odd, because the configuration takes twenty minutes and the conversation is what determines whether the rule survives the month.

Here is what those conversations sound like at three stages, including the questions you will actually be asked.

Before any of them: decide what you believe

Children of every age can detect a rule you do not really hold. If you cannot finish the sentence "we do this because…" without reaching for "because I said so," the rule will not survive contact.

So work out, for yourself, which of these you are actually doing:

Protecting from accidental exposure. Mostly relevant under ten.
Protecting attention. The most common real motivation and the one parents are most embarrassed to name.
Holding a family value. Legitimate, but only if it applies to the whole family.
Managing your own anxiety. Also legitimate, and worth naming privately, because it tends to produce rules that are stricter than the situation and harder to explain.

You do not have to share this analysis with your child. You do have to have done it, because the first question you will be asked is why.

Age 7: keep it small and true

At seven, the explanation should be shorter than you think and should not be about them.

"I have set this tablet up so that some parts of the internet do not show up. There is a lot of the internet that is made for grown-ups and some of it is upsetting, and I would rather you did not run into it by accident while you are looking for something else. It works the same way on my phone."

That is the whole thing. Three sentences, one of which is the important one.

What they will ask:

"What kind of stuff?" Do not be specific, and do not be evasive either. "Things made for adults, and things that try to trick people into paying money." Both are true and neither creates a target.

"Can I see it?" "No, that is the point." Cheerfully. This is not a negotiation at seven and does not need to sound like one.

"Is it because I did something?" Worth answering even if they do not ask, because young children often assume rules are consequences. "No. It has been like this since before you had the tablet."

What to avoid: framing it as watching them. A seven-year-old who thinks the device reports on them will not tell you when something upsetting happens on it, which is the single behaviour you most want to preserve.

Age 11: bring them into it

Eleven is where the conversation stops being an announcement and starts being a negotiation, and where most parents keep making the announcement.

The shift is from "I have set this up" to "here is what I think, what do you think."

"You are getting more of your own life online now, and I want to be straight with you about how this is set up rather than have you find out by bumping into it. Adult content and gambling are blocked, on everyone's devices in this house including mine, and that is not going to change. What I am less sure about is the time side. Some things are set to be off during homework and after bedtime. I would rather agree that with you than impose it, so tell me what you think is fair."

Two moves in there are doing the work. The first is separating the non-negotiable part from the negotiable part, so there is something real to negotiate. The second is the "including mine," which at this age is the sentence they will actually remember.

What they will ask:

"Why do you not trust me?" The honest answer is usually that trust is not the mechanism. "It is not about trust. If a site tries to trick you, I do not want you to have to be clever enough to spot it, at eleven or at forty. I have the same thing on my phone for the same reason."

"Everyone else can use it." Do not argue about whether that is true. "Maybe. This is what we have decided here, and here is the reason." Then stop, rather than defending it for ten minutes, which signals it is defensible rather than decided.

"What if it blocks something I need for school?" This is the most important question they will ask, and the answer must be concrete. "Tell me and I will fix it that evening." Then do it. The first time you fix a wrongly blocked school site within the hour, the whole arrangement becomes credible in a way no explanation achieves.

The thing to say that most parents leave out: what the filter does not do. "This does not show me your messages and it does not tell me what you looked at. It stops some sites loading, that is all." Say it unprompted. They are already wondering, and the version they imagine is worse than the truth.

Age 15: hand over as much as you can

At fifteen the technical facts have changed. They can use mobile data, a friend's phone, or the settings screen. Any rule now works because it is agreed, not because it is enforced.

That sounds like a loss of control. It is actually the moment to spend the credibility you have been building.

"You are old enough that I cannot really enforce this, and I am not going to pretend otherwise. So I want to tell you what I am keeping and why, and hand you the rest.

I am keeping the malware and phishing blocking. That is not about you, it is on my phone too, and it stays on forever as far as I am concerned. Getting your accounts stolen at fifteen is a genuinely bad year.

The adult content filter I am also keeping, because it is a thing we believe in this family and it applies to all of us. You can disagree with me about it and I will still keep it, and I would rather have that argument out loud than quietly.

Everything else, I am taking off. The social apps, the video sites, the time schedules. Not because I think they are good for you, but because you deciding about them is the actual skill, and you have about three years to practise it while I am still here."

What they will ask, or more likely say:

"Finally." Let that land. Do not undercut it.

"So you are just going to trust me?" "Mostly. And I will notice if it goes badly, and I will say so, and then we will talk about it. That is different from trusting you never to make a mistake."

"Why do you get to keep the adult content one?" Answer honestly rather than technically. If it is a value, say it is a value. If you cannot articulate why it applies to a fifteen-year-old and to you, that is worth noticing before the conversation rather than during it.

The move most worth making at this age: give them a focus tool they control. A mode they can switch on themselves during exam revision, that blocks the things they know pull at them, that you cannot see and do not administer. A teenager who chooses to block distractions for three hours has learned the thing you were trying to teach for a decade. A teenager whose parent blocks them has learned to wait until they move out.

The three sentences that carry all three conversations

Whatever the age, three things do most of the work:

"It applies to me too." More persuasive than any reasoning, at every age.
"Here is what it does not do." Volunteered, not extracted. Removes the version they are imagining.
"Tell me if it gets in the way and I will fix it today." And then actually do it.

Everything else is detail. The rule you can explain, that you also live under, and that bends when it is wrong, is the one that is still there in two years.

Frequently asked questions

Should I tell my child that filtering is on, or set it up quietly?+

Tell them. A filter they discover by hitting it is a filter they will try to defeat, and a parent who set something up quietly has taught a lesson about how this household handles disagreement. Telling them costs almost nothing at seven, is essential at eleven, and at fifteen is the difference between a household rule and a thing being done to them. The only version of quiet setup that makes sense is security filtering against malware and phishing, which is closer to a smoke alarm than a rule and does not really need announcing.

What do I say when they point out that their friends have no rules?+

Take it seriously rather than dismissing it, because it is often true and it is genuinely hard. The answer that works is a reason rather than a comparison: this is what we have decided in this house, here is why, and here is the part of it that applies to me too. What does not work is arguing about what other families do, which you cannot win and which moves the conversation away from your actual reasoning.

My teenager found a way around the filter. What now?+

Treat it as information rather than as a betrayal. A teenager who routes around a rule is usually telling you the rule no longer fits, that it blocked something they needed, or that they were not part of setting it. Ask which. Then decide whether the right response is a tighter technical control, which rarely holds at that age, or a renegotiated rule they had a hand in. In most households the second one lasts longer.

Is it hypocritical to filter their devices and not mine?+

Children notice this at about ten and stop taking the rule seriously at about eleven. You do not have to apply identical settings, because the situations genuinely differ, but you do have to be able to explain the difference in a way that sounds like a reason rather than an excuse. Applying the security filtering and at least one content category to your own devices too is a small cost and it changes how the whole thing reads.

What to Block at 7, 11 and 15 (and What to Stop Blocking)

The mistake is not being too strict or too lenient. It is setting rules once at age seven and never revisiting them, so a teenager is governed by decisions made for a child.

Keeping a teen's phone safer, without spying on them

You can filter harmful content and manipulative app design at the network level without reading a single message. Protection and privacy are not opposites. Here is how to keep both.
