Online safety at age 7 looks very different from online safety at age 15 — and parents who apply seven-year-old strategies to teenagers, or who unlock platforms for maturity before a child is ready, tend to encounter problems. A developmentally appropriate, evolving approach — more structure early, more autonomy as trust is established — works better than a fixed set of rules at any age.
Ages 5–8: Foundation
Children this age need supervision, not software. Devices should be used in common areas. Co-viewing — sitting alongside your child as they watch YouTube or play games — is the most powerful protective practice at this stage. Establish that grown-ups can always look at a device; this normalizes transparency rather than surveillance. Basic digital literacy at this age: people online are not always who they say they are; private information (our last name, our address, our school name) is never shared; if something feels wrong, tell a grown-up and you won't be in trouble.
Ages 9–12: Structure
This is when devices increasingly enter children's independent use — including the first smartphone for many families. Content filtering and parental controls are highly appropriate at this age. The goal is not to prevent all bad content (you can't) but to reduce casual exposure and maintain visibility into what your child is encountering. Set up device-based Screen Time or Family Link controls. Establish a family rule about devices not being in bedrooms. Have the primer conversation about pornography and stranger danger at the low end of this range, not the high end.
Ages 13–15: Negotiation
Adolescents are developing identity and autonomy — pure restriction strategies create conflict and push behavior underground. The goal shifts from control to coaching. Have explicit conversations about specific platforms before they're used. What will you do if you receive something explicit? What's our family policy on sharing your location? Who are the people you're talking to in that game? Establish visibility without invasiveness: 'I'm not reading your messages, but I can see that you were on Instagram at 1 AM, and that's not okay.'
Ages 16–18: Preparation
The approaching reality of independent adult digital life means this is the time to build self-regulation skills your child will need when they're no longer under your oversight. What are your own standards for what content you consume? How do you handle it when someone online makes you feel bad? What's your plan if something you share online gets used against you? The practical parental controls matter less at this stage than the internalized values and skills they'll carry into college and beyond.
