Online Safety for Kids by Age: Ground Rules, Parental Controls and Warning Signs From Preschool to Teens • Living Life as Moms | Mom Hacks, Toddler Snacks, and Kids Activities

Quick answer: online safety for kids works best as a set of rules that grows with your child. Young children should use devices in shared spaces with content you have chosen; school-age kids need clear rules about personal information, strangers and asking before downloading; tweens need help with group chats, gaming and the minimum age of 13 that most social platforms set; and teens need privacy settings, open conversations about sextortion and scams, and a plan for what to do if something goes wrong. Pair the rules with parental controls, a family media plan and a promise that your child can come to you without losing their device.

The internet is where kids learn, play, talk to friends and, increasingly, do homework. It also brings risks that are hard to see from across the room: strangers in game chats, scams, cyberbullying and pressure to share photos. The answer is not to keep kids offline forever, but to teach skills step by step, the way you would teach crossing the street.

This guide is part of our family health and safety guide. It lays out what pediatric and federal guidance recommends, the ground rules that fit each age and how to respond when something goes wrong.

Table of Contents

Major health and safety organizations agree on a few core points. The American Academy of Pediatrics recommends that families create a Family Media Plan, a written set of rules about when, where and how devices are used, and update it as children grow. The AAP also advises avoiding screen media other than video chatting for children younger than 18 to 24 months, and limiting screen use for children ages 2 to 5 to about one hour a day of high-quality programming watched with a parent.

In 2023, the U.S. Surgeon General issued an advisory on social media and youth mental health. It said there is not enough evidence to conclude that social media is safe for children and adolescents, and it encouraged families to create tech-free zones, model healthy use and teach kids about online safety and privacy.

Federal law also shapes what kids see. The Children’s Online Privacy Protection Act, enforced by the FTC, requires websites and apps directed at children under 13 to get verifiable parental consent before collecting personal information. That is the main reason most social media platforms set 13 as their minimum age in their terms of service.

For daily time limits by age, see our guide to screen time for kids by age.

Online Safety Rules for Preschoolers (Ages 2 to 5)

At this age, safety comes almost entirely from the setup. Young children cannot judge what is safe, so adults choose the content and stay close.

Use devices in shared rooms, not bedrooms or behind closed doors.
Choose apps and videos ahead of time, and use kids’ profiles or child-focused apps with autoplay turned off where possible.
Watch together and talk about what you see.
Lock app stores and purchases behind a password.
Start simple rules: “We ask before we tap something new” and “Tell a grown-up if anything looks scary or confusing.”

Online Safety Rules for Kids Ages 6 to 9

Early elementary kids start using school accounts, learning games and sometimes video calls with relatives. They can learn the first real rules about personal information.

Keep personal details private. No full name, address, school name, phone number or photos shared without a parent.
Strangers online are still strangers, even if they seem nice or say they are a kid.
Ask before downloading any app, game or file, and before clicking pop-ups or ads.
Use kid-safe search settings and filtered video apps.
Keep chat turned off in games, or limited to approved friends.
Practice what to do if something upsetting appears: close the screen or turn the device over and get an adult.

Give praise when a child reports something. The goal is a child who tells you, not one who hides problems to avoid trouble.

Online Safety Rules for Tweens Ages 10 to 12

The tween years bring the biggest jump in online risk. Many kids get their first phone, join group chats and play multiplayer games with voice chat. Most mainstream social media apps are not meant for this age group: their terms require users to be at least 13.

Agree on a phone contract that covers where the phone sleeps at night, which apps are allowed and what happens if rules are broken.
Review privacy settings together on every app, including location sharing.
Talk about group chats. Screenshots can be shared, and messages are rarely as private as they seem.
Set gaming rules, such as chatting only with friends they know offline and never moving a conversation to another app at a stranger’s request.
Teach scam spotting: free game currency offers, fake giveaways and requests for passwords are common tricks.
Keep devices out of bedrooms overnight, which also protects sleep.

Online Safety Rules for Teens Ages 13 to 17

Teens need more independence, and the rules shift from control to coaching. The aim is a teen who can handle problems on their own and still knows they can come to you.

Set accounts to private and review who can message, tag or find them.
Think before posting. Photos, comments and messages can be saved and shared, even on apps that promise they disappear.
Never share intimate images. Explain that creating or sharing sexual images of anyone under 18 is illegal, even between teens, and that anyone pressuring them is a red flag.
Talk directly about sextortion. The FBI has warned of a sharp rise in cases in which criminals, often posing as teens, persuade young people, frequently boys, to send explicit images and then demand money or more images.
Protect accounts with strong unique passwords and two-factor authentication.
Watch for scams involving jobs, money transfers, online purchases and fake friend requests.
Keep talking about how social media makes them feel. The Surgeon General’s advisory noted concerns about sleep, body image and exposure to harmful content.

Setting Up Parental Controls

Parental controls are a backstop, not a replacement for rules and conversation. Kids, especially older ones, can find ways around them. Still, they help a lot with younger children. Common layers include:

Layer	What it can do
Device settings (phone, tablet, computer)	Screen time limits, app approval, content ratings, downtime schedules, purchase locks
Home router or internet provider	Filter websites for every device on the network, pause internet at bedtime
App and platform settings	Restricted modes on video apps, teen account defaults, chat limits in games
Game consoles	Age ratings, spending limits, chat and friend request controls
Search engines	Safe search filtering

Set controls up together with older kids and explain why each one is there. A teen who understands the reason is more likely to accept it and to come to you if a setting blocks something they need for school.

Cyberbullying: Signs and What to Do

Cyberbullying is bullying through texts, apps, games or social media. StopBullying.gov, run by the U.S. Department of Health and Human Services, lists warning signs such as a child suddenly avoiding devices or using them far more, seeming upset after being online, hiding the screen when an adult walks in, withdrawing from friends or not wanting to go to school.

If your child is being bullied online:

Stay calm and listen. Thank them for telling you.
Do not respond to the bully and do not let your child retaliate.
Save evidence with screenshots of messages, usernames and dates.
Block and report the account on the platform.
Contact the school if classmates are involved; many schools have policies covering online bullying.
Contact police if there are threats of violence, sexual images of a minor or stalking.

Our older article on how to teach internet safety to your kids has conversation starters you can use alongside these steps.

Online Predators, Grooming and Sextortion

Grooming is the process an adult uses to build trust with a child in order to exploit them. NCMEC describes common patterns: excessive flattery, gifts such as game currency, requests to keep the relationship secret, attempts to move to a private app and gradually more personal or sexual conversations.

Teach these rules plainly:

Real friends do not ask you to keep secrets from your parents.
Never send photos to someone you have not met in person.
If someone threatens you, it is not your fault, and you will not be in trouble for telling.
Do not pay or send more images. The FBI advises that paying rarely stops the threats.

If something happens, stop contact, keep the messages and report to the CyberTipline. NCMEC’s Take It Down service can help remove or stop the spread of explicit images of people taken when they were under 18.

Build a Family Media Plan

A written plan makes rules consistent and easier to enforce. Cover these points, and revisit them at the start of each school year or when a child gets a new device:

Where devices are used and where they charge overnight.
Tech-free times, such as meals and the hour before bed.
Which apps and games are allowed and who approves new ones.
Privacy rules for names, photos, location and passwords.
What to do if something scary, mean or confusing happens.
Consequences for breaking rules, kept separate from punishment for reporting a problem.

The AAP’s online Family Media Plan tool walks you through each section. Discussing it at a weekly family meeting gives every child a voice.

Frequently Asked Questions

At what age should a child get a phone?

There is no single right age. Many families wait until a child shows they can follow rules and needs a phone for safety or logistics, and start with a basic phone or tightly limited smartphone. A phone contract and parental controls help either way.

What age is appropriate for social media?

Most platforms require users to be at least 13 because of COPPA rules. The Surgeon General’s 2023 advisory raised concerns about social media use in early adolescence, so many experts suggest waiting as long as possible and supervising closely at first.

Should I read my child's messages?

For young children, regular check-ins on devices are reasonable and should be part of the rules from the start. With teens, many parents shift to periodic reviews they discuss openly, stepping in more if there are signs of danger.

What should I do if my child sees something inappropriate online?

Stay calm, thank them for telling you, talk about what they saw in age-appropriate terms and adjust filters or settings. Report illegal content involving children to the CyberTipline.

How do I know if my child is being groomed online?

Warning signs include secrecy about online friends, new gifts or game currency, sudden mood changes, using devices late at night and an adult or older teen who seems unusually interested in your child. Talk with your child and report concerns to NCMEC or police.

The Bottom Line

Online safety for kids is not one conversation or one app setting. It is a set of rules that grows with your child: close supervision for little ones, clear privacy rules in elementary school, careful steps into phones and chat for tweens and coaching for teens on privacy, scams and sextortion. Add parental controls, a written family media plan and an open door, so your child tells you when something feels wrong.
