Virtual autism & screen time

To grow up healthy, children need to sit less and play more

WHO 2019 guidance on physical activity, sedentary behaviour, and screen time for children under five — including the recommendation of no screen time for under-ones and no more than one hour for two- to four-year-olds.

Screen time and digital technology use: pre-schoolers

A practical Raising Children Network guide to healthy screen use for pre-schoolers — how much, what kind, and how to build a household routine. Includes guidance on co-viewing and on replacing passive watching with active play.

Virtual autism

A term used by some researchers to describe autism-like signs in very young children that they link to prolonged early screen exposure. It is not a formal diagnosis, the research is still developing, and screens are not the only factor in any individual child. Soira treats it as one piece of a wider conversation about screens, language, and the early years.

Screen time

The time a child spends in front of a screen — TVs, phones, tablets, computers. The WHO recommends zero screen time under age one and no more than an hour of supervised, high-quality content per day for children aged two to four. Active, co-viewed time is generally considered less concerning than passive scrolling.

Passive screen exposure

Watching a screen on your own without interaction or back-and-forth conversation. The concern is that passive watching displaces the kind of serve-and-return play that helps a young brain build language and connection. Co-viewing — where an adult talks with the child about what they are seeing — looks very different.

WHO screen-time guideline

The World Health Organization's 2019 guidance for children under five recommends no screen time for under-ones, no more than one hour per day for two- to four-year-olds, and prioritising physical activity and sleep. The numbers are guidance — context (what content, with whom, instead of what) matters as much as duration.

AAP screen-time guideline

The American Academy of Pediatrics suggests avoiding screens for children under 18–24 months except for video chats, limiting media to short, supervised, high-quality content for ages 2–5, and building a family media plan that fits each household. Similar in spirit to the WHO guidance, with more flexibility on co-viewing.

Co-viewing

Watching media together with your child and talking about what you are seeing. Co-viewing turns passive watching into a shared activity — the adult points things out, asks questions, names emotions — and is generally considered far less concerning than solo screen time.

Background TV

A television playing in the room while a child is doing something else. Even when nobody is watching directly, background TV reduces the amount of language young children hear from adults and the quality of parent-child interaction. Turning it off when it is not actively being watched is a small, high-impact change.

Autoplay

The feature on streaming services that automatically queues the next video. Autoplay turns a short, intentional viewing session into a long passive one, especially for young children who cannot self-regulate stopping. Most platforms let you turn it off in account settings — a small change with outsized effect.

Media displacement hypothesis

The idea that the main concern with early screen time is not the screen itself but what it replaces — back-and-forth conversation, play, sleep, time outside. Two hours of high-quality content alongside a rich day looks different from two hours that crowd out everything else.

Serve and return

The everyday back-and-forth between an adult and a young child — a coo, a look, a smile, a question, a pointing finger. Researchers at Harvard's Center on the Developing Child describe serve-and-return as one of the most important things adults can offer a young brain. Screens at their worst displace it; at their best, adults co-view and keep it going.

Media mentoring

A way of framing the parent's role with screens — not gatekeeper but guide. You choose the content together, talk about it, and model healthy screen habits yourself. Media mentoring assumes screens will be part of the child's life and focuses on how to use them well.

Early language environment

The pool of words and conversational turns a child is exposed to in the first years of life. Rich, responsive language environments support language development; quiet ones (or ones dominated by background noise from screens) do less. The mix of vocabulary, conversational turns, and reading aloud all matter.
