How much screen time is right for learning English at 4 to 8?

There is no special screen-time number for learning English: for children aged 2 to 5, health experts advise no more than about one hour of screen time a day, and for ages 6 to 8 they give no fixed number. A short English session of 10 to 15 minutes on most days, with you nearby, fits easily inside that advice, and experts say that how a child uses the screen matters as much as the minutes.

What do health experts advise for ages 4 and 5?

  • World Health Organization (2019). For children aged 3 and 4: "Sedentary screen time should be no more than 1 hour; less is better" (WHO). Sedentary means sitting still.
  • UK government (March 2026). For children aged 2 to 5: about one hour a day, not at mealtimes or in the hour before bed (gov.uk). The expert report behind it suggests "short chunks (30 minutes or less)" and says to "keep solo screen use to a minimum" (UK expert report).

WHO's limit does not treat learning apps differently from cartoons, so an English learning game still counts as screen time.

What about ages 6 to 8?

There is no official number of hours for this age.

  • WHO (2020), for ages 5 to 17: children "should limit the amount of time spent being sedentary, particularly the amount of recreational screen time" (Chaput and colleagues, 2020).
  • American Academy of Pediatrics (January 2026). The AAP no longer sets one fixed limit. If parents want one, a doctor can discuss limits that fit the family's routine. In the AAP's words: "Time limits might range from <1 hour/day for toddlers and preschoolers to 1 to 2 hours/day or more of entertainment (not school-related) media for school-aged children and teens. The most important considerations are high-quality content and prioritizing healthy activities (eg, sleep, play, physical activity, reading)" (AAP, 2026).

Are these limits based on strong evidence?

Not very strong, and the experts say so. The UK report states: "The evidence on time thresholds for screen use in the early years is very limited." The AAP says most studies in this field are observational: they find links, not proof of cause. So treat the hour as a careful upper limit, not as a line that science has proven.

Can my child learn English from cartoons?

Some words, yes. But watching alone is not the best way, especially for younger children.

  • Children can pick up words from TV. In an older study, 3- and 5-year-olds learned new words from a 15-minute program (Rice and Woodsmall, 1988).
  • Young children learn less from video than from a person. A review of 59 reports on children up to age 6 found that they learned less from video than face to face. The gap got smaller with age (Strouse and Samson, 2021). The UK report says the gap "may persist until around school age."
  • In everyday life, the links are small. In a review of 63 studies, the ones about children's everyday screen use found no overall link with vocabulary, except for educational media, which had a small positive link (Jing and colleagues, 2023). Another review, of 42 studies, found that more screen time and background TV went with slightly weaker language, while educational programs and watching together went with slightly stronger language (Madigan and colleagues, 2020).

Most of these studies looked at children's first language, not a new one, and they show links, not proof.

What is the difference between watching and playing together?

Two things make screen time better for learning: your child takes part, and you join in.

  • Taking part. The UK report puts it simply: "Interactivity is key to educational benefits." But not every tap helps. In a study with 2-year-olds, children learned a new word when they had to touch the thing that was named. Touching anywhere on the screen did not help. For slightly older toddlers, who could already learn by watching, the touching seemed to get in the way (Kirkorian, Choi and Pempek, 2016). So more tapping is not always better. Look for games where your child finds the thing they heard.
  • Joining in. The AAP says the good effects of high-quality educational media are stronger when a caregiver watches together or teaches.

For example:

  • Watching alone: your child watches English cartoons alone for 30 minutes.
  • Playing together: for 10 minutes, your child finds "the red apple" in a game. You say, "Apple! Can you find an apple in our kitchen?" and your child runs to the fruit bowl.

How many minutes of English a day?

No study gives an exact best number for this age. But the UK expert report suggests short chunks of 30 minutes or less for ages 2 to 5. And spreading words over many days helps: in a study with 2-year-olds, the number of different days they heard new words mattered most for saying them (Childers and Tomasello, 2002).

So we suggest 10 to 15 minutes on most days, plus English without a screen: a song in the car, "Where is the spoon?" while you cook, or a picture book at bedtime.

How do I choose good English screen time?

When researchers scored the most-downloaded children's "educational" apps, "overall scores were low" (Meyer and colleagues, 2021). So check for yourself. These questions are based on the AAP, the UK report and the studies above:

  • Is it slow and calm? The UK report asks for content that is "slow-paced, repetitive and predictable".
  • Does it have a clear learning goal? For example, words for things at home.
  • Does my child act on the word? Finding, matching or moving the thing that was named.
  • Does it avoid ads and distractions? The AAP lists ads, "frequent rewards for play" and "excessive interactive elements" as signs of lower-quality content.
  • Can I join in? The AAP suggests "a shared family tablet (vs. one that belongs only to the child)".

Do language apps work for young children?

In experiments, young children do learn some new words from screens (Jing and colleagues, 2023). But we found no strong trial of an app that teaches a new language to children aged 4 to 8. And the AAP says that "children will not miss out on learning opportunities if families delay giving their children a tablet." An app can be one helper, not the whole plan.

How Kadoo fits

Time in Kadoo is screen time, so count it in your child's day. You choose how long each session lasts, from 10 to 30 minutes, and you can add a daily limit; when time is up, the puppy says it's time to rest. Kadoo has no ads and no links that take a child out of the game, and children show they understand a word by finding, feeding or coloring the thing that was named. The parents' area shows how many minutes your child has played. Kadoo doesn't listen to your child speak, so talking about the words together is still your part.
