If you have been asking whether all screen time is bad for kids, the newest research says no. A review of 30 studies from the University of Georgia found that the effect of screens on young children depends on their age, what they watch and whether a parent watches with them, as well as on the number of hours. A well made show watched together is a different thing from a toddler alone with an endless stream of videos.

There are two caveats, and they matter. The benefits showed up mainly in preschoolers, roughly ages 3 to 5. For babies and toddlers, heavier screen use was still linked to weaker language. So the hours still count, especially for the youngest children and especially in the evening.

## What the University of Georgia review of 30 studies found

The review, by Minal Manisha and William Schneider, was [published in the Journal of Evidence-Based Social Work](https://www.tandfonline.com/doi/full/10.1080/26408066.2026.2725613). It looked at children in low-income families, because earlier research suggests they spend more time with media, according to [UGA Today](https://news.uga.edu/is-all-screen-time-bad-for-children/).

A few named shows came out well:

- **Daniel Tiger** was linked to better social skills.
- **Sesame Street, Between the Lions and SuperWhy!** were linked to stronger letter and sound recognition among some preschoolers.

The press release gives no effect sizes, so I can't tell you how big those gains were. The phrase "among some preschoolers" is doing real work there.

The same review found harms too. In infants and toddlers, heavier use was linked to poorer language development and smaller vocabularies. Evening media use was linked to sleep problems. And heavy use can push out reading, outdoor play and family time.

## Is all screen time bad for kids? Age changes the answer

A 4 year old can plausibly pick up letter sounds from a show built for that. A 1 year old is still learning mostly through play and people talking to them. That is why "educational" is no free pass for under-2s: the review that found literacy gains in preschoolers also linked more screen time in babies and toddlers to poorer language.

For context on how common screens are at this age, a [UCL study](https://www.ucl.ac.uk/news/2026/jan/toddlers-spending-two-hours-screens-day) surveyed more than 4,700 parents of 2 year olds in England in 2023/24 and assessed the children's vocabulary. 98% of the toddlers watched screens on a typical day.

**129 minutes**: Average daily screen time for 2 year olds in England, from a survey of more than 4,700 parents ([UCL News, Children of the 2020s study](https://www.ucl.ac.uk/news/2026/jan/toddlers-spending-two-hours-screens-day))

Only 34% met the WHO limit of an hour or less, and about a fifth regularly played computer games. Higher screen use was linked to poorer language and more emotional and behavioural difficulties, and toddlers in disadvantaged families used screens more. This shows a link, not proof that screens caused the problems. If your 2 year old goes over an hour, you are in the majority, which is a reason to adjust, not to feel terrible.

For the very youngest, I have covered a Singapore cohort separately in [what a 10-year study found about screen time for 1 year olds](https://ivehadit.app/blog/screen-time-for-1-year-old-study).

## The hours still count, mostly because of what they replace

Much of the worry about screens is about displacement. An hour on a tablet is an hour without books, outdoor play or chatting at the table. And screens in the evening were linked to sleep problems in the Georgia review, which is its own knock-on effect for the next day.

Longer studies add some calm. A Scottish cohort that followed children from age 5 to 15, [reported by News-Medical](https://www.news-medical.net/news/20260824/Researchers-followed-children-for-a-decade-to-see-whether-screen-time-really-mattered.aspx), found limited and inconsistent links between screen use and emotional, behavioural and social development. Early high use was linked to more difficulties at 10, but that faded by 15, when only very high gaming stood out. Several links weakened once the researchers adjusted for other factors.

Put together, a bit of screen time looks unlikely to do lasting damage. Sustained heavy use, and screens close to bedtime, are the parts worth your attention.

## Watching together can be as light as answering one question

Co-viewing, in the review's sense, means watching with your child, answering their questions or talking about the show afterwards. The authors stress that it does not mean turning every cartoon into a lesson, and they warn against one-size-fits-all rules ([UGA Today](https://news.uga.edu/is-all-screen-time-bad-for-children/)).

In practice that might be sitting down for the last five minutes of an episode. Or asking "why was Daniel cross?" in the bath later. Or singing the letter song from Super Why! on the walk to nursery. None of that needs a plan.

## A chosen show and an autoplay feed are different habits

Most of the research in the review was about television. The authors point out that today's devices are portable, personalised and shaped by algorithms, so a child can carry an endless run of recommended videos from room to room. The older studies don't capture that.

So here is my inference, and it is only an inference: the benefits in the review came from specific, well made programmes. Picking one of those is a different habit from handing over an app that decides what plays next. Nobody has shown the feed version is worse, but nobody has shown it carries the same benefits either.

## Six things to try with a toddler or preschooler

1. Pick the show yourself: choose a specific, age-appropriate programme instead of letting an app autoplay whatever comes next.
2. Watch together when you can: even a few minutes, plus a question or two afterwards, counts as co-viewing.
3. Be strictest with the youngest: for ages 2 to 4, the [WHO](https://www.who.int/publications/i/item/9789241550536) recommends an hour a day or less, and for babies and toddlers heavier use is linked to weaker language.
4. Keep the hour before bed screen-free: evening media use was linked to sleep problems in the review.
5. Protect play, books and talk first: fit screens around them, since part of the harm is what screens replace.
6. Skip the panic over small amounts: the links in longer studies are mostly modest and correlational, so sustained heavy use is the thing to cut.

> **Let the episode end the session** Choose shows with a clear ending and switch off autoplay in the app's settings before you hand it over. When the episode ends, the screen goes quiet, and stopping becomes the default instead of a negotiation.

Your own screen habits are part of this too. I looked at that in [does my phone use affect my child](https://ivehadit.app/blog/does-my-phone-use-affect-my-child).

## Most of this research shows links, and much of it is about old TV

Treat all of this with a bit of caution. Most studies in this area are observational, so they show screen time and outcomes moving together without proving one causes the other. Families who use screens heavily often differ in other ways too.

The Georgia review focused on low-income families, so it may not apply evenly to everyone. Most of its studies were about television, not tablets or video apps. And the press release gives no effect sizes, so "linked to better social skills" could mean a small nudge or a large one.

- Screen effects on young children depend on age, content and co-viewing, as well as hours.
- Benefits from shows like Daniel Tiger and Sesame Street appeared mainly in preschoolers, not babies or toddlers.
- For infants and toddlers, heavier use is still linked to poorer language and smaller vocabularies.
- Screens in the evening were linked to sleep problems, so a screen-free hour before bed is a solid default.
- Picking a specific show and watching some of it together is a realistic goal for tired parents.

If the feed you find hardest to put down is your own, I built I've had it to close social media feeds in the browser while leaving the rest of the internet open. ([How it works](https://ivehadit.app/start))

## Questions people ask

### Is educational TV like Sesame Street or Daniel Tiger good for toddlers?

A review of 30 studies linked Daniel Tiger to better social skills and Sesame Street, Between the Lions and SuperWhy! to stronger letter and sound recognition, but mainly among some preschoolers aged about 3 to 5. For babies and toddlers, the same review linked heavier screen use to poorer language, so educational labels matter less at that age.

### How much screen time is okay for a 2 year old?

The WHO recommends no more than one hour a day for children aged 2 to 4. A UCL study found 2 year olds in England averaged 129 minutes a day and only 34% met the one hour limit, so treat it as a goal to work towards.

### Does watching TV with your child make it better?

The University of Georgia review found that whether a parent watches along is one of the factors shaping screen effects. Co-viewing can be as simple as answering questions or chatting about the show afterwards, and the authors say it doesn't need to become a lesson.

### Is screen time before bed bad for young children?

The review linked evening media use to sleep problems in young children. Keeping the last hour before bed screen-free is a reasonable default.

### Does screen time cause speech delay?

Heavier screen use in babies and toddlers is linked to poorer language and smaller vocabularies, but most studies are observational and can't prove screens are the cause. Swapping some screen time for talking, reading and play is still a sensible move.
