Screen time for preschoolers: what the guidelines actually say
3 min read · reviewed against WHO / CDC / AAP guidance
For children aged 2–4, the WHO recommends no more than 1 hour of sedentary screen time per day — less is better. The AAP similarly suggests about 1 hour per day of high-quality programming for ages 2–5, watched together with a caregiver when possible.
Why the limit exists
It isn't that screens damage children directly — it's what the hours displace: active play, conversation, and sleep. A preschooler's day is short; an extra hour of video is usually an hour taken from movement or an later bedtime.
Quality and context beat the stopwatch
An episode of a slow-paced show watched with a parent who talks about it is very different from autoplay videos alone in a bedroom. If you're choosing battles: protect the hour before bed, keep screens out of the bedroom, and prefer content you'd be comfortable watching together.
A practical setup that works
Pick one predictable screen window — for many families, 30–60 minutes that ends before dinner. A visible routine ("screen time ends when the timer rings, then we set the table") removes the daily negotiation, which is usually the exhausting part.
