What's the short answer?

Across 51 studies of 83,862 children aged 4–6, more screen use was linked to worse wellbeing — and the largest link of all was with the quality of the parent–child relationship. Watching and playing together softened the pattern.

What did the study do?

A systematic review and meta-analysis combined 51 studies of 83,862 children aged 4–6, looking at digital technology use against overall wellbeing, social and behavioural functioning, and parent–child relationship quality.

What did it find?

More use was associated with worse overall psychosocial well-being (r = −.12), social functioning (r = −.06) and behavioural functioning (r = −.10).
The largest association was with worse parent–child relationship quality (r = −.13).
In studies that measured context, co-using technology and home learning with parents softened the pattern.

What it didn't prove

These are associations from mostly observational studies — linked to, not proof of cause — and the effect sizes are small. The review doesn't set a “safe” number of minutes.

🌙 One thing to try tonight

Convert some solo screen time into together time: co-watch, co-play, and talk about what is on the screen while it is on.

Frequently asked questions

So is all screen time bad at this age?

The review found small average links, not a verdict on every child or every show — and context mattered: using screens together looked different from solo use.

What's the most useful takeaway?

The relationship finding: how screens fit around parent–child time may matter as much as the minutes themselves.

The takeaway

You don't have to win the minutes war to act on this paper — turning some solo screen time into together time is the move the evidence points to.
