Screens, Honestly

There is no version of modern life in which a small child never sees a screen, and the official guidance is less settled than the arguments about it suggest. Here is what the main bodies actually say, where they disagree, and what the evidence supports doing about it.

What the guidance actually says

The World Health Organization takes the strictest line. No sedentary screen time for children under one, none recommended at one year, and no more than an hour, with less being better, for two to four year olds. It sits inside a wider set of recommendations covering movement, sleep and time spent sitting still across the whole day, which is the more useful way to read it.

The American Academy of Pediatrics held a similar position for years: nothing before around eighteen months apart from video chat, and about an hour of good programming for two to five year olds, watched together where possible. The AAP's more recent guidance moves the emphasis off a single daily number and onto what is on the screen, who is watching alongside, and what the screen is displacing. It still says that infants under eighteen months learn best from real world interaction and that heavy solo screen use can affect language and social development.

The UK was the vaguest of the three for a long time, with the NHS avoiding a fixed number and the Royal College of Paediatrics and Child Health pointing at the WHO figures. More recent UK guidance for under fives lands on around an hour a day and no solo watching for under twos, and describes its own approach as precautionary. That word is doing honest work. The evidence here is thinner than the confidence of most headlines about it.

• WHO: none under two, up to an hour for two to four, less is better
• AAP: very limited under five, and since 2026 weighted towards content and context rather than a clock
• UK guidance: around an hour for under fives, and no solo watching under two
• All three are most cautious about the under twos
• None of them count a video call with a grandparent the same way

They agree on the direction and differ on the number. Nobody has the exact answer.

Why video calls are different

Every set of guidelines carves out video chat, and the reason is mechanical rather than sentimental. A call is contingent. The person on the screen responds to your child, pauses when they pause, says their name, waves back at the right moment. That live back and forth is what babies learn language and social behavior from, and it does not much matter that it is arriving through glass.

It works better with an adult in the room narrating and pointing, particularly under two. Keep calls short, ask the person at the other end to talk to your child rather than over them to you, and expect your child to wander off partway. Wandering off is not rudeness. It is the length of their attention.

Watching together does the work

There is a well documented pattern in which children under about three learn something less well from video than from the same thing shown to them in person. Researchers call it the video or transfer deficit, and it is one of the sturdier findings in this area.

What narrows the gap is an adult. In study after study, toddlers who cannot pick up a new word from a clip on their own manage it when a parent is alongside asking questions, naming what is on the screen and tying it back to the room. Children also look at the screen more when the adult with them is doing that. It becomes a thing you are both looking at, which is much closer to how everything else is learned at that age.

So the useful question is not how many minutes, but whether anyone else is in the room. Twenty minutes with you pointing and asking is a different object from twenty minutes alone, even though the tablet reports the same number. It also means slow beats fast. Something with pauses, repetition and a world you can recognize will support a conversation. Something with a cut every second will not.

The television nobody is watching

The screen most worth changing is usually the one on in the background. When a television is on and nobody is watching it, adults talk less to the children in the room. Researchers observing families at home have recorded fewer words, fewer different words and fewer questions directed at the child while a set is on, and less responsiveness overall. Adult speech is the main raw material for language, so that is the route by which background television appears to matter.

This is good news, because it is the easiest thing on the whole list to change and it costs your child nothing they wanted. Off during meals, off during play on the floor, off when nobody has actually chosen to watch it. If you want sound in the house, music does not seem to carry the same problem, and it does not compete for your eyes.

The haircut, the flight, the waiting room

Sometimes the screen is the right tool. A tablet on a long flight, a phone through a haircut, a video during a blood test or in a waiting room at the end of a very long day. Pediatric writing names these situations directly as reasonable, and there is no evidence that occasional use in a hard moment does harm.

The distinction worth holding is between a screen used for a situation and a screen used as the standard answer to a feeling. Handing over a phone every time a child is bored, cross or upset removes the practice they need at handling those states, and that pattern is what the guidance is aimed at. Once every two weeks on a train is not that pattern, and it does not need to be atoned for.

• Decide before you leave the house what the screen is for, so it is a plan rather than a surrender
• Say when it ends in terms they can see: when this one finishes
• Download it in advance, so the ending is not decided by the wifi
• Sit alongside if you can, even for part of it
• Do not narrate guilt about it afterwards, to them or to yourself

The other half of this is your own screen, which is harder. Children read attention, and they read it accurately. There is no need for a purge, but putting your phone face down and out of your hand for the first twenty minutes after pick up will do more than any rule you set for them.

Ask what the screen is replacing. That answer is more useful than the number of minutes.

This is general information, not advice about your child. Guidance differs by country and is still changing, so follow your own national body. If you have concerns about your child's speech, hearing, attention or development, or about screen use that seems to be displacing sleep, meals or play, talk to your pediatric nurse, doctor or pediatric professional rather than working it out from a chart.

Where this comes from: the World Health Organization, the American Academy of Pediatrics, the NHS.
