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

Most families set up parental controls once. A child gets their first tablet at six or seven, a parent spends an evening configuring things, and that configuration stays roughly in place for the next decade while the child does not.

The result is a fifteen-year-old living under rules written for a seven-year-old, and a parent wondering why those rules have stopped working.

Filtering is not a single decision. It is three or four different decisions made at different stages, each with a different purpose, and the loosening is as important as the blocking.

Age 7: the goal is accident prevention

A seven-year-old is not seeking anything out. They are typing a word into a search box, tapping a recommendation, or following a link from a game. Almost everything that goes wrong at this age is an accident.

That makes the policy simple, and it is the one stage where being strict costs almost nothing.

Block broadly:

• Adult content, as a category rather than as a list.
• Gambling, which reaches children mainly through game-adjacent sites and app promotions.
• Dating.
• Known malware and phishing, which is worth having on every device in the house regardless of who uses it.

Turn on safe search. This does more practical work at this age than any blocklist, because most accidental exposure comes through search and video recommendations rather than through browsing to a site.

Keep the device in shared space. This is not a technical control and it outperforms every technical control at this age.

What not to bother with: elaborate time limits enforced by software. At seven, an adult saying "that is enough now" is more effective and much less brittle than a schedule that fights bedtime for you.

The important thing to understand about this stage is that you are protecting against randomness, not against your child. Nothing here is about distrust, and it is worth saying that out loud even to a seven-year-old, because it sets the frame for the harder conversations later.

Age 11: the goal shifts to shaping habits

Somewhere around ten to twelve, two things change at once. The child starts seeking things out rather than stumbling on them, and social life moves onto the device.

Strictness stops being free here. A filter that blocks everything a peer group uses does not protect a child from the peer group; it just moves the child's social life to a friend's phone, where you have no visibility and no conversation.

Keep blocking: adult content, gambling, malware and phishing. These stay for years.

Start distinguishing categories from time. At eleven the problem is usually not what a child can reach but how long the reaching goes on. Filtering a category is a blunt tool for that. What tends to work better is a schedule that applies to the distraction-heavy apps at specific hours, homework time and after bedtime, while leaving the rest of the day alone.

Be willing to unblock things. A child at this age will hit a wrongly blocked site for school. How you respond to that is the whole ballgame. Fix it the same evening and the filter stays credible. Say "I will look at it later" three times and your child will start solving the problem themselves, in ways you will not hear about.

Talk about what is blocked and why. Not a list of forbidden sites, which reads as a menu. A category and a reason: "adult content is blocked on every device in this house, including mine." That last part matters more than it sounds.

Watch the messaging apps. This is the point where most of what actually affects a child stops being a website. Filtering does very little here, and pretending otherwise is how parents end up feeling covered while missing the thing.

Age 15: the goal is a supervised runway

Fifteen is the stage most families handle worst, usually by not handling it at all.

A fifteen-year-old can defeat almost any household filter if they decide to. They know about mobile data, about other people's phones, about the settings screen. The question is no longer whether you can enforce a rule. It is whether you can retain enough credibility to be the person they come to when something goes wrong.

That reframing changes what is worth keeping.

Keep, indefinitely: malware and phishing protection. This costs nothing in autonomy, protects them from things they cannot reasonably evaluate at any age, and should probably stay on their devices forever, including yours.

Keep, with a conversation: adult content filtering, if it is a family value you can articulate and are applying to everyone. What does not survive is a filter that applies to the teenager and not to the adults, because at this age the double standard is the message.

Start removing: category blocks on social platforms, video sites and the general run of things their friends use. Not because those things are harmless, but because a blanket block is no longer doing the work you want and is costing you the relationship that would.

Replace with something better: a shared expectation about phones at night. The single highest-value intervention at this age is not a content filter, it is the phone not being in the bedroom at 1am. That is a household norm, not a technical setting, though a schedule can support it.

Give them the controls. A genuinely useful move at fifteen or sixteen is handing over a focus mode they control themselves, for exam periods or for work they care about. A teenager who chooses to block distractions during revision has learned something a parent-imposed block cannot teach.

The loosening is the point

Parents talk a lot about what to block and almost never about the schedule for removing it. But the goal was never a filtered childhood. It was an adult who can navigate an unfiltered internet.

That means the filter has to come off at some point, deliberately and while you are still around to talk about it. A child whose first unfiltered internet is the one in a university dormitory has been protected right up until the moment protection mattered least and then handed the whole thing at once.

A reasonable schedule looks something like this:

• 7 to 10: broad category blocking, safe search on, shared spaces.
• 11 to 13: same categories, plus time shaping rather than more blocking, plus a real conversation about what is filtered and why.
• 14 to 16: categories narrow to the ones you can justify to their face. Time shaping moves toward a household norm rather than an enforced schedule. They get controls of their own.
• 17 onwards: security filtering only. Everything else is a conversation.

What no filter will do

It is worth ending on the limit, because the biggest risk of a well-configured filter is the feeling of completeness it creates.

The things that most affect children online are mostly not blockable. A group chat that turns cruel. A friend who shares something that should not have been shared. A video that arrives by message rather than by search. A slow drift into comparing themselves with strangers. None of these involve a domain you could have added to a list.

Filtering makes the baseline quieter, which is genuinely worth having. It buys attention back, it removes the accidental exposure, and it takes a category of risk off the table so you can spend your attention on the categories that are still on it.

The rest is the part that has always been the parenting.

If you want to set this up

The practical version is one profile per child, with different settings by age, so a seven-year-old and a fifteen-year-old in the same house are not governed by the same rule. Configure the phone itself rather than only the router if the device leaves the house.

You can create an account on the free tier, or read the setup guide to see what configuring a device involves.
