Not all screen time is bad for young children, University of Georgia review finds

Not all screen time affects young children in the same way: what they watch, how old they are and whether a parent watches with them matter as much as how long the screen is on, according to a systematic review led by Minal Manisha of the University of Georgia, published in the Journal of Evidence-Based Social Work and publicised by the university in late October 2026. The review screened 30 quantitative studies of children aged up to eight in low-income families in the United States. It linked prosocial programmes, which model kindness, cooperation and empathy, to better social skills, and violent content to more aggressive behaviour. Educational programmes were associated with literacy and social benefits, while heavier screen use among infants and toddlers was linked to poorer language development. The authors highlight co-viewing, parents watching and talking about programmes with their children, as a simple, promising strategy.

Most advice on children and screens focuses on a single number: how many hours. That is easy to measure and easy to follow, but it says nothing about what is on the screen. This review brings together evidence from families with limited means, the households that often have the least time and money for alternatives, and finds that content and context change the picture.

For parents, the message is practical. A gentle programme about sharing and friendship is not the same as a violent cartoon, even if both last 20 minutes. Age matters too: the review links heavier screen use at that age with poorer language development. For older preschoolers, well-made educational shows were associated with literacy gains.

The most useful finding may be about parents themselves. Co-viewing does not require special training or money. Sitting with a child for part of a programme, answering their questions and talking afterwards about what happened can help turn watching into learning. In homes where grandparents, older siblings and working parents share childcare, whoever is with the child can do it.

The review's caution against rigid rules is also important. Manisha argued that families differ in their schedules, resources and needs. A working single parent and a joint family with several adults at home will manage screens differently, and advice that ignores this is unlikely to be followed.

Short-term: The review gives parents, teachers and health workers evidence-based talking points: choose content carefully, limit screens for the youngest children and watch together when possible.

Long-term: Its focus on low-income families could shape public guidance and support programmes, shifting the message from simple time limits to content, age and parental involvement.

Who is affected: Parents and caregivers of children up to age eight, early childhood educators, paediatricians and social workers, and makers of children's television and video content.
