Screen time for kids
There is no perfect screen-time number. There are better and worse defaults — and the difference matters.
What the research actually shows
The American Academy of Pediatrics broad guidance: under 18 months, no screens except video calls. 18–24 months, limited high-quality programming with a parent watching alongside. 2–5 years, 1 hour/day max of high-quality programming. School-age, consistent limits with priority given to sleep, homework, exercise, and offline social time.
The strongest finding from the last decade of screen research isn't about total time; it's about what gets displaced. Screens that replace sleep, outdoor play, or in-person conversation correlate with worse outcomes. Screens that replace nothing important do less harm.
Content quality matters more than duration
30 minutes of Bluey is not the same as 30 minutes of YouTube algorithm slop. Live-action shows where actors look at the camera and talk to the viewer (Mr. Rogers, Sesame Street) actually correlate with positive social development. Algorithmic short-form video (TikTok, YouTube Shorts, Instagram Reels) correlates with attention problems.
Practical defaults
- No screens in bedrooms — sleep is the easiest thing to protect.
- No screens at meals — meal-time conversation predicts vocabulary growth.
- One hour before bed: nothing. Blue light + dopamine = sleep disruption.
- Co-view when possible — watching with your kid lets you talk about what you saw.
- Phones out of pockets at the dinner table — adults too. Modeling matters more than rules.
Teens are different
For 13+, total screen time is less useful as a metric than which apps and at what times. Banning everything tends to push usage underground; limiting specific high-risk patterns (Snapchat at 2am, infinite-scroll feeds) works better.
