Why one rule rarely fits every child
Parents are often told to follow a single number: so many minutes a day, or a fixed age for a first device. In practice, children differ in temperament, family circumstances and what they actually do on screens. A video call with a grandparent, a homework task and an endless feed of short clips are all “screen time”, yet they have very little in common.
A more useful approach is to think about what a child is doing, who they are doing it with, and whether the activity is suited to their age. The sections below describe common benefits and concerns at different stages. They are general observations, not a prescription, and families will reasonably reach different conclusions.
What technology can offer
Devices can be genuinely useful. Depending on the child and the activity, they can support:
- Learning and curiosity. Reference tools, educational games and video explanations can help a child explore a topic at their own pace. The wider debate about technology in education covers how much of this holds up in classrooms.
- Connection. Messaging and video calls keep children in touch with relatives and friends who live far away.
- Creativity. Drawing, music making, video editing and simple coding are all possible on ordinary devices.
- Accessibility. For some children with disabilities or learning differences, devices offer ways to read, communicate or take part that would otherwise be harder.
- Play and downtime. Games and shows can be a reasonable source of enjoyment, in the same way books or television have been.
Common concerns
The worries are also real, although their size varies between children and is often debated.
- Content. Children can come across material that is not meant for them, whether in a video, a game or a search result.
- Contact. Chat features can put children in touch with people they do not know.
- Time and sleep. Screens can crowd out sleep, physical play and face-to-face time, especially when used late in the evening.
- Spending. Some games and apps are built around in-game purchases, which can be confusing for young children.
- Data. Apps may collect information about children, and online tracking does not distinguish much between adult and child users unless a service is designed for them.
- Mood and self-image. Older children may compare themselves with others online, and the discussion of social media mental health is ongoing and nuanced.
Early years: toddlers and pre-schoolers
For very young children, many health bodies have generally suggested keeping screen use limited and doing it together where possible. At this age, shared activities such as looking at photos or watching a short programme with a parent tend to be more valuable than solo use. Choosing a small number of known, ad-light apps is usually easier than handing over a device with an open browser.
Primary school years
Children of roughly five to eleven are often keen to use games, video platforms and, increasingly, messaging. This is a sensible time to keep devices in shared spaces, agree what is allowed, and use tools such as parental controls as a safety net rather than a substitute for conversation. It is also a good age to begin talking about online strangers, spending in games, and what is and is not appropriate to share.
Check what a game’s age rating means before agreeing to it. Ratings describe content, not whether a game’s chat features or purchases suit your child.
Early teens
Many children get their first phone around the transition to secondary school, though there is no fixed right age. Teens place more weight on privacy and independence, and heavy-handed monitoring can backfire by encouraging them to hide things. Topics that matter most here include group chats, bullying, photo sharing, sleep, and the long-lasting nature of what they post. Because teenagers often notice tricks parents miss, it helps to understand how recommendation algorithms shape what appears in their feeds.
Older teens
As young people approach adulthood, the aim shifts from control to judgement. Reviewing privacy settings together, discussing how employers and schools may see public profiles, and talking about money and scams prepare them for managing technology alone. Tolerance for mistakes matters: a teenager who expects to be punished for a problem is less likely to mention it.
Habits that tend to help at any age
- Keep an open, low-drama habit of talking about what children see and do online.
- Set a few clear, consistent household routines, such as no devices at meals or in bedrooms overnight.
- Use device and app settings to reduce risk, but treat them as imperfect.
- Model the behaviour you want. Children notice how adults use their own phones.
- Revisit rules as the child grows. What worked at seven will probably not work at thirteen.
- Pay attention to changes in mood, sleep or friendships, which can matter more than hours logged.
A note on digital well-being
Wider questions about digital well-being apply to adults as much as children. Families often find it easier to agree on shared limits than to impose them on one person. If you are worried about a child’s mental health or safety, a family doctor, school counsellor or a recognised child-support service is a better source of advice than any article, including this one.
