Now that the school year is underway, teachers are making their first observations about how this year's class settles into a story at circle time. It is a good moment to look at a shift in the data that we think is underrated — and that reframes the screen-time conversation we wrote a guide about last year.
The number that did not change
Here is the surprise in Common Sense Media's most recent census of media use by children under eight, published in 2025: total screen time held roughly steady at about two and a half hours a day.
Parents who feel they are losing an arms race may find that oddly reassuring. The total is not running away.
The number that did
What changed is the composition. Short-form video — TikTok, YouTube Shorts, Instagram Reels — went from about one minute a day to fourteen. Even children aged zero to two now average about four minutes a day of it. Gaming rose sharply over four years. Traditional television declined.
Alongside that: about 40 percent of children have a tablet by age two, and nearly one in four has their own phone by age eight.
So the same two and a half hours is now made of very different material. And there is reason to think the material matters more than the total.
Why format is not a detail
A twenty-two-minute episode, whatever you think of it, has a structure: a beginning, a problem, a middle that requires you to hold information, and a resolution. Following it is a small act of sustained attention. A child who watches one has practiced staying with something.
Short-form video is built on the opposite principle. Each clip is engineered to deliver a complete payoff in seconds, and the next one is already arriving. Nothing needs to be held in mind. Nothing is unresolved long enough to require patience.
Neither is poison. But they are different exercises, and one of them looks a lot more like the thing we ask children to do with a book.
That connection is not hypothetical. In a January 2026 EdWeek Research Center survey of more than a thousand early educators, teachers reported children arriving who struggle to attend to a book — to sit with a page while a story unfolds slowly. Teacher observation is not proof, and we would not present it as such. But it is a consistent signal from the people who watch four-year-olds encounter books for a living, and it points the same direction as the format shift.
The gap that is actually fixable
The most actionable finding in the census is about co-viewing — whether an adult is watching alongside.
Roughly 62 percent of parents at least sometimes watch YouTube with their child. Only about 17 percent do the same with TikTok.
That gap is understandable. Short-form video is watched in short bursts, often handed over in a waiting room or a checkout line, and it does not invite an adult to sit down. But co-viewing is close to the whole ballgame for young children, because what actually drives early language is back-and-forth conversation with an adult. A show you watch together generates talk: what happened, what might happen, why the character did that. A feed watched alone generates none.
So the format is not only harder to follow. It is also the format adults are least likely to be present for.
What we would suggest
Nothing here calls for panic, and we are not going to tell you to eliminate anything:
- Watch the shape, not just the clock. Two hours of one show is a different experience than two hours of scrolling. Trading some short-form minutes for longer-form ones is a smaller ask than cutting the total, and probably does more.
- Sit down for the short stuff sometimes. You do not need to watch it all. Watching a few and talking about them closes the co-viewing gap where it is widest.
- Protect the slow things. Books, puzzles, and long stretches of unstructured play are practice at staying with something. They are the counterweight, and they matter more the more short-form a child sees.
- Look at your own scrolling. Children calibrate to what adults model. This one is uncomfortable and worth naming.
The reframe
For years the parenting question has been how much. The data suggests a better one: what is it, and are you in the room? Those are easier questions to act on than a daily minute budget — and on the evidence, they are the ones that count.
