Short answer: For under-2s, the WHO and AAP advise avoiding screens (other than video chatting), and from age 2 to 5 keeping it to around an hour a day of high-quality content, ideally watched together. For school-age children there's no single official number — UK guidance deliberately sets no fixed limit and instead asks whether screens are crowding out sleep, exercise, play and family time. The most useful rule isn't a stopwatch: protect the things that matter first, keep screens out of the hour before bed, and model good habits yourself.
Before the numbers, one reassuring thing: there's no evidence that a sensible amount of good screen time, balanced with plenty of the other stuff childhood needs, harms a healthy child. The worry in the research isn't the screen itself so much as what heavy use can displace — sleep, active play, conversation, and the slow, absorbing play where young children actually build attention. Keep those protected and you've done most of the job. With that in mind, here's the age-by-age picture.
Screen time recommendations by age
Two of the most cited sources are the World Health Organization (which issued guidance for under-5s) and the American Academy of Pediatrics (AAP). They line up closely for the early years:
- Under 18 months–2 years: avoid screens. The WHO recommends no sedentary screen time for children under 2 — none at all before age 1, and none for 1-year-olds. The AAP says to avoid screen media other than video chatting before 18 months, since babies and toddlers learn best from real, back-and-forth interaction with people.
- 18 to 24 months: only if it's high quality, and watched together. If you do introduce screens in this window, the AAP advises choosing high-quality programming and watching it alongside your child to help them make sense of it — not leaving them to it alone.
- 2 to 5 years: about an hour a day, less is better. The WHO caps sedentary screen time at no more than 1 hour a day for ages 2 to 4, and says less is better. The AAP similarly recommends limiting ages 2 to 5 to around an hour a day of high-quality programming, ideally co-viewed with an adult.
- 6 years and up: consistent limits, not a fixed number. For school-age children the AAP stops giving an hourly cap and instead advises consistent limits that make sure screens don't get in the way of enough sleep, physical activity, and other healthy behaviours.
Notice the through-line: under fives get clearer numbers, older children get principles. That's deliberate — as kids grow, what they're doing on a screen (and what it's replacing) matters far more than the raw total.
Why UK guidance doesn't give one magic number
Parents often go looking for "the NHS screen time limit" and come away confused, because there isn't a single official UK figure. The Royal College of Paediatrics and Child Health looked at the evidence and concluded it simply isn't strong enough to set one limit that fits every child. Rather than a stopwatch, its guidance asks four practical questions: is screen time controlled? Does it get in the way of what your family wants to do? Does it interfere with sleep? And are you able to keep snacking in check while it's on? It also suggests avoiding screens in the hour before bed. In other words, the UK approach is about displacement — if screens are crowding out sleep, exercise, play and time together, that's your signal to pull back, whatever the clock says.
What actually helps — starting with a hero who learns focus
Limits land far better when they're not the whole strategy. The deeper goal isn't just less screen time — it's a child who can settle into the slow, absorbing play and reading where attention is really built. One of the gentlest ways to grow that is to give your child a character who learns focus first, in a story, with nothing of their own at stake. In Focused Silver, Silver the Super Pup is trained in the superpower of focus: deciding where his attention goes, taking a big scary mountain one step at a time, and treating every wobble as fuel for getting stronger. Read together at bedtime — exactly the slot you're trying to keep screen-free — it does double duty: it fills the wind-down with something calm and shared, and it hands your child a language for choosing their own focus. "Remember how Silver took just the first step?" is a far softer nudge back to a puzzle or a drawing than "stop asking for the iPad."
“If you want to climb a mountain, don't focus on the whole mountain — just focus on the first step.”
Focused Silver — a superhero training story that turns focus, attention and a calm "I can't… yet" mindset into a superpower your child wants to practise. A warm, no-nagging way to make a screen-free bedtime something they look forward to.

Setting screen limits without the daily battle
1. Fill the day with the good stuff first
The simplest reframe: don't start with screens and try to claw time back — start with meals, outdoor play, reading and sleep, and let screens fill what's genuinely left over. When the day is already rich, the tablet becomes a small part of it rather than the main event, and "that's enough now" causes far less friction.
2. Make the rules clear, predictable and boring
Children push hardest against rules that change with your mood. Agree simple, steady boundaries — when screens happen, where, and what counts as "good" content — and stick to them. A predictable "after tea, two episodes, then off" is easier for a child to accept than a negotiation every single time, because there's nothing to argue about.
3. Give a warning before it ends
Snatching a screen away mid-moment guarantees a meltdown. A simple "two more minutes, then we switch it off" gives a young child time to land, just like any other transition. Pair it with what comes next — "screen off, then we'll set the table together" — so the ending points somewhere, rather than into thin air.
4. Protect sleep — keep screens out of the bedroom and the hour before bed
This is the one most worth holding firm on. Screens in the hour before bed, and screens in the bedroom, are strongly linked to worse sleep — and a tired child struggles far more with focus, mood and everything else the next day. Make the wind-down a screen-free zone and fill it with a bath, a chat and a story instead.
5. Watch with younger children, and model it yourself
For under-fives especially, co-viewing turns passive watching into shared attention — you naming things, asking questions, linking it to real life. And nothing shapes a child's screen habits more than watching the adults around them. If your own phone is always in your hand, that's the lesson that lands, whatever the household rule says.
Try this. For one week, swap the half-hour before bed from screens to a story. Notice how your child settles — easier wind-downs and calmer mornings are often the first thing parents spot, and it's the single change with the strongest evidence behind it.
The takeaway
For the early years the guidance is genuinely clear: avoid screens under two, keep it to about an hour a day of good, shared content from two to five, and protect the play and sleep around it. After that, let go of the perfect number and watch the displacement instead — if screens aren't stealing sleep, movement, play or time together, you're very likely fine. Set steady limits, guard bedtime fiercely, give your child absorbing things to do off the screen, and hand them a hero who makes focus look like a superpower. That combination does more for a child's attention than any timer ever could.
