Screen time rules for kids: three rules that hold, by age, and what to say at switch-off

It's 6:15. Dinner is nearly ready, and you say the sentence you say every evening: “Two more minutes, then the tablet goes off.” Two minutes later you say it again, louder. Then comes the scream, the tablet in your hand, a child on the floor, and you eating dinner with a knot in your stomach, wondering whether other families have this too. They do. This guide covers what a screen does at each age, from two to sixteen, a handful of rules that hold, what to say at switch-off time, your own phone, and the signs that mean it's time to ask for help.

There is no right number of minutes

Start here, because it takes a weight off. There is no number of minutes that's right for every child, and anyone who gives you one is guessing. A four-year-old watching a cartoon on your lap is doing something different from a four-year-old alone with a tablet for the same twenty minutes. An hour of video calls with grandma is not an hour of short videos that never end.

Four questions tell you more than a timer. What is on the screen? When is it on, and what does it push out: sleep, dinner, playing outside, homework? Who is with the child? And how does the child come out of it: ready to move on, or in pieces? If the answers are mostly fine, the number is fine. If the answers worry you, cutting ten minutes won't fix it.

Two to four

At this age a screen is mostly a pacifier for the adult. That's not a judgment; it's a Tuesday at 5:40 with a pan on the stove. The trouble is that a toddler's brain can't yet pull itself away from moving pictures, so every ending is an ending you have to make. That's why the switch-off is so loud at this age.

What helps: short, and together. A screen on your lap with you naming what's happening is closer to a picture book than to television. Same slot every day, not whenever things get hard, because “whenever things get hard” teaches a two-year-old that screaming turns a screen on. And no screen in the hour before sleep; the light and the pace keep a small body in daytime long after the tablet is off.

If you can, keep the screen out of the stroller and the car on short trips. Boredom in a stroller is where a toddler learns to look at the world.

Five to eight

Now the screen gets its own pull: a game with levels, a show with the next episode already loading. A six-year-old can't feel time pass in there. Ten minutes and forty minutes feel the same from inside. So “you've had enough” means nothing to them, and the fight at the end comes from real surprise, not defiance.

Make the end visible before the start. “Two episodes” is a better rule than “thirty minutes”, because the child can see where it ends. And pick the slot: after homework and before dinner, say, so the screen never competes with sleep or with the table.

This is also the age to start talking about what's on the screen, not just how much. “Why did that character do that?” “What would you have done?” Five minutes of this does more than any filter, and it tells your child that what they watch is something you're interested in, not something you're policing.

Nine to twelve

The first phone usually arrives here, often because “everyone has one”. Before it does, decide three things: where it sleeps (not the bedroom), which apps are on it, and who can look at it (you, for now, and that's said out loud before the phone is handed over, not after). A phone that comes with the rules attached feels like a deal. A phone that gets rules bolted on later feels like a punishment.

Group chats start at this age, and so does the first real drama in them. Being thrown out of a chat hurts as much as being left out of a party. Keep the door open: “If something in a chat makes you feel bad, show me, and I won't take the phone away.” And mean it. The quickest way to lose sight of what happens online is to make the phone the price of telling you.

Games get more social now. Leaving a round with friends halfway really does cost something, so warn before the round starts, not during, and let the child pick the stopping point within the limit.

Teenagers

A teenager's phone is where their friends are, their music, their jokes, their first love and their first humiliation. Taking it away is not like taking away a toy. It's like locking the front door. That's why bans at this age produce lying, not less screen time.

What still works: conditions, agreed together, once, at a calm moment. The phone charges in the kitchen overnight, yours too. No phones at dinner, yours too. School nights have an off time. Beyond that, the question shifts from “how much” to “how are you”. Is there still sport, a friend in the flesh, sleep, a face that lights up about something that isn't on a screen? If yes, the hours are probably fine even when they look like a lot to you.

Talk about what they see, not just how long. Ask what's funny right now, what's annoying, who they'd trust. Sideways, in the car, without eye contact. A teenager who shows you a video is handing you the door key.

Rules that hold

Most screen rules fail for one of three reasons: there are too many, nobody can see them, or they're only for the children.

Few. Three rules a seven-year-old can repeat beat ten rules in a document. For most families: a slot (when the screen is on), a place (where it never is: the table, the bedroom), and an end (how the switch-off happens). Everything else is negotiable.

Visible. Written on the fridge, in the children's words, with the children's drawing if they're small. A rule on the fridge is not you being strict. It's just the rule. You can point at it instead of saying it for the fourth time.

The same for the adults. If the phone is banned at the table and you check yours between courses, the rule is dead by Thursday. Children don't follow what you say about screens. They follow what you do with yours. The rules that hold in most houses are the ones the parents keep too, visibly, with a bit of groaning.

The fight at switch-off time

A seven-year-old, tablet, episode ending, you said five minutes. The five minutes are up.

“Time's up. Tablet off.”

“One more! It's nearly finished!”

“I know it's hard to stop in the middle. Pause it, and it'll be here tomorrow at the same time.”

“That's not fair! You never let me!”

“You're angry. Okay. The tablet is still going off. Do you want to press it or should I?”

“...I'll do it.”

“Thanks. Come, dinner's ready, I want to hear about that level.”

What's happening: you're not arguing about fairness, you're not counting down a fourth time, and you're not pulling it out of their hands while they hold on. You name the feeling, keep the end in one place, give one small choice, and offer something on the other side. The first three evenings are loud. By the fourth, most children stop testing, because the test stopped producing extra minutes.

If the tablet gets thrown or you get hit, that's not a screen problem any more; that's a big feeling with no words yet. The screen still goes off. The child gets you, close, until the storm passes. Then, later and calm, you talk about what else to do with a feeling that size.

Your own phone

This is the section nobody wants, so it's short. Your child learns what a phone is for by watching you. If it's the thing that takes you away mid-sentence, that's what a phone is. If it's the thing you turn face-down and ignore when they walk in, that's what a phone is.

Try one week of three small things: the phone stays in your bag for the first ten minutes after pickup. It's not on the table at dinner. And it charges outside the bedroom. You'll notice how often your hand goes looking for it. That's useful information about what you're asking of your child.

When to get help

Most screen fights are ordinary. Some are a sign of something underneath. Talk to your pediatrician, the school counselor or a family counselor if you see several of these for more than a few weeks:

Sleep: regularly awake past midnight on the phone, exhausted in the morning, falling asleep at school.

Withdrawal: friends in the flesh have dropped away, sport or the hobby got dropped, the door is closed and stays closed, meals are skipped to stay online.

Aggression: switching off produces not just anger but hitting, broken things or threats, and it's getting worse, not better.

School: grades falling, homework not done, the teacher calling, and the screen is the only thing that still gets full attention.

Mood: your child seems flat, anxious or ashamed about something that happens online and won't say what it is.

For a teenager, the sudden change is the sign to take seriously: not a lot of screen time as such, but a child who was fine in September and is someone else in November. None of these mean something is badly wrong. All of them are reasons to have someone look, together with your child, not behind their back.

One thing to do tonight

Pick the place. Decide the one spot where screens are never on, for anyone, starting tonight. For most families that's the dinner table. Say it once, out loud, before dinner: “From today no phones at the table. Mine too.” Put yours in the kitchen drawer where they can see it. Don't change anything else yet. One week of one visible rule that the adults keep is where most screen rules start to hold.

What the app has for this

In TrustParent, screens sit in a few places. The weekly plan has slots per child, so “screen after homework, until dinner” is written once where the child can see it, and you can stop saying it. The question cards at dinner give the phone-free table something to do, because an empty silence is where everyone reaches for a pocket. If your child lives in two homes, the handover carries the screen rules along with the medication and the gym bag, so the same end holds in both. And the practice “One evening a week without screens”, which you tick off for a week. If you're not sure where to start, Mila asks two questions and suggests one thing. Just one.
