Under-5s Online: Start Smart, Build Good Habits

Your under-5 doesn’t need a smartphone. But the moment they touch one—at a grandparent’s house, during a long car journey, or because they’re curious—their relationship with screens has begun. The habits they form now, in these early years, shape how they’ll use devices for the rest of their childhood. The good news: it’s far easier to build healthy habits from the start than to undo bad ones later.

Why under-5s need different rules

Young children have no concept of privacy, permanence, or strangers on the other side of a screen. They don’t understand that a video they watch is made by a real person, or that people online can’t always be trusted. They’re also developing attention spans and learning to regulate emotions—two things screens can easily disrupt.

This doesn’t mean banning devices altogether. It means being intentional about how, when, and what your child encounters. The research is clear: children who grow up with consistent, calm boundaries around screens develop better digital habits than those who face rules only after problems appear.

Supervision is the foundation

For under-5s, active supervision is non-negotiable. This doesn’t mean hovering; it means being present and engaged.

• Watch together, even for short clips. Ask questions: “What’s happening here? Who is this person?” A parent who watches Cbeebies alongside their child for 10 minutes learns far more than a parent who leaves the child alone for an hour.
• Keep devices in shared spaces. A tablet on the kitchen table or a TV in the living room is easier to supervise than a screen behind a closed door. You’ll notice what they’re watching.
• Sit with them during first encounters. The first time your child uses an app, a streaming service, or a new device, be there. You’ll see what confuses them, what holds their attention, and what upsets them.
• Use parental controls as a safety net, not a babysitter. They stop accidental clicks and block obvious adult content. They don’t replace your presence.

Device placement and timing matter

Where and when your child accesses screens shapes their habits long-term.

• No screens in bedrooms. If they fall asleep watching, they’ll expect it every night. If they wake at 3am and reach for a device, their sleep cycle suffers. A device in the kitchen or living room means you control access.
• No screens in the hour before bed. The light and stimulation make sleep harder. If bedtime is 7pm, screens go away by 6pm. This is one of the few rules that neuroscience strongly backs.
