Online Safety by Age and Stage

Online safety by age and stage begins with understanding what children need to develop, not simply knowing which settings to switch on. As children grow, their interests, judgement, relationships and exposure to online risks change. Parents need to adjust their guidance as children gain independence, while protecting time for play, learning, sleep and real friendships.

Children of the Digital Age (CODA) strongly advocates a smartphone-free and social media-free childhood. We recommend that primary school children do not own smartphones or use social media. For older children, delay access for as long as reasonably possible and introduce independence gradually, with appropriate guidance. Choose your child’s age group below for more detailed advice.

Protect a Smartphone-Free and Social Media-Free childhood

A smartphone brings the internet, private messages, games, videos, purchases and social feeds into almost every situation. A child who needs to contact a parent does not necessarily need access to all those services. Consider a basic call and text phone where communication is necessary, or a shared device for supervised educational and recreational use. Accessibility, medical and communication needs may require individual arrangements.

The Department of Education and Youth’s Keeping Childhood Smartphone Free guide supports parents and school communities in making collective choices. Its 2025 primary school circular also requires schools to restrict pupils’ use of and access to personal mobile phones during the school day. Families can extend that protection beyond school through shared agreements, alternatives for arranging social activities and consistent boundaries at home.

A 2026 Pediatrics study of 10,588 US participants found that smartphone owners at age 12 had 31% higher odds of depression, 40% higher odds of obesity and 62% higher odds of insufficient sleep than nonowners, after adjustment for several other factors. These figures describe associations in the study, not the probability of harm to an individual child. The research cannot prove that smartphones caused these outcomes. Nevertheless, it supports a precautionary approach to early ownership.

Delaying a smartphone should not mean excluding children from friendship groups or ordinary family communication. Help children organise time with friends, take part in clubs and sport, and pursue interests that do not depend on a personal screen. If other parents share your concerns, agree common arrangements so children do not feel singled out.

Social Media readiness is not a birthday

Many mainstream social media services set a minimum account age of 13, although rules differ by service and country. Reaching that age does not establish that a teenager is ready for public attention, comparison, inappropriate contact or pressure to share private information. CODA recommends no social media throughout primary school and delaying access well into adolescence wherever possible.

The American Psychological Association’s health advisory highlights the importance of adult guidance in early adolescence, when peer feedback can become particularly significant. Young people need opportunities to practise judgement and respond to conflict without the pressures of public metrics or constant connectivity. Even if a teenager eventually needs a smartphone, installing social media is a separate decision.

In Ireland, the age of digital consent is 16 where a provider relies on consent to process a child’s personal data in the relevant circumstances. The minimum age of an account, an app rating and this legal threshold are different things. The Data Protection Commission explains the distinction in its guidance on parental consent, linked in the references below. Never enter a false date of birth to bypass an age restriction.

How online risks change as children develop

Age helps us understand which risks and decisions may become more relevant. However, children develop differently, and threats are not limited to particular age groups. Use these stages as a starting point rather than a deadline for providing new technology.

  • Under 5: Prioritise attachment, language, movement, imaginative play and sleep. Avoid personal devices and unrestricted viewing. Adults should select content, supervise any permitted use and protect children’s photographs and personal information.
  • Ages 5 to 8: Children may confidently navigate games without understanding advertising, unknown contacts or why they find it difficult to stop. Keep childhood free from smartphones and social media. Teach simple personal information rules and help children recognise when something feels wrong.
  • Ages 9 to 12: Friendship and belonging can influence requests for smartphones, gaming accounts and group chats. Maintain primary school boundaries while teaching children about persuasion, grooming, bullying, spending and online privacy. Offer practical ways to stay connected without social media.
  • Ages 13 to 15: Growing independence and the search for identity can make peer approval, body image, online relationships and private messaging important. Discuss sexual pressure, intimate images, sextortion, harmful recommendations, AI relationships and the consequences of sharing material. Continue to delay access where possible.
  • Ages 16 to 17: Prepare young people for adult decisions about money, employment, relationships, consent and account ownership. Address scams, gambling, reputation, misinformation and cybersecurity while maintaining a dependable route to adult support.

Understand the psychology of online engagement

Children learn to manage emotions, solve problems and understand others through experiences and practice. A younger child may need help interpreting a video or recognising an advert, while an older child may understand the technology but struggle to resist social pressure. Technical competence does not demonstrate emotional readiness. It is important to understand both the child and the products they use.

The American Academy of Pediatrics’ 2026 digital ecosystems policy draws attention to the environments in which children use technology, including commercial incentives and design. Features such as autoplay, endless feeds, notifications and rewards can make stopping more difficult. Some services also profit from advertising, purchases or longer engagement. Parents should recognise these design choices rather than assume every difficulty is a failure of discipline.

Talk about what a platform wants the child to do next. Ask why a game offers a limited time reward, why a video service immediately starts another video, or why a social app displays popularity figures. Understanding the design can help a child recognise persuasive techniques. Adults must still set boundaries appropriate to the child’s stage of development.

Protect sleep, play, learning and family relationships

Ask what recreational technology may be replacing, rather than counting minutes alone. The HSE guidance on screen time recommends avoiding screen time for the youngest children, apart from appropriate video calls, and ideally limiting screen time for ages two to five to one hour a day. For older children, adequate sleep, activity, social contact and hobbies remain priorities. Educational and accessibility uses deserve separate consideration.

Set predictable routines and protect bedrooms, meals and shared family time from unnecessary devices. Give children the chance to be bored, create their own games and solve problems without immediately reaching for a screen. Parents can also model these habits by putting their own phones away when listening or playing. Children should experience the attention that adults expect them to give in return.

Recognise online manipulation and emerging threats

Children do not need a social media account to encounter grooming, scams or inappropriate content. Multiplayer games, messaging services and video platforms can also expose them to unwanted contact. As the Australian eSafety Commissioner’s grooming guidance explains, offenders may build trust through attention, gifts or apparent friendship before seeking secrecy or sexual contact. Teach children never to move a conversation to a private app simply because a person they met online requests it.

Online bullying, pornography exposure, harmful challenges and pressure to share images can occur in familiar digital spaces. Explain that an image or video may be altered or created using AI, and that a convincing voice or profile does not prove someone’s identity. Children should know they can leave an uncomfortable interaction and tell an adult, even if they have already made a mistake. Parents can explore CODA’s gaming, messaging and scams resources for more detailed advice.

AI tools also introduce the possibility of simulated friendships. The Australian eSafety Commissioner’s 2026 survey examined experiences of 1,950 children aged 10 to 17 with assistants and companions. Although an assistant can help a user with a task, a companion can imitate affection, remember personal details and encourage ongoing interaction. Children need to understand that apparently caring responses do not represent genuine human understanding.

CODA advises against children and teenagers using AI companions designed to simulate intimate or personal relationships. A Common Sense Media risk assessment likewise recommends against use of social AI companions by minors after evaluating harmful responses in tested products. For educational AI, use suitable supervised tools and encourage children to think, verify and learn rather than simply outsource their work. See our AI Safety Hub for further guidance.

Why parental controls are not enough

Parental controls can restrict purchases, content, access times and some forms of contact. However, a filter cannot reliably identify every harmful image, determine another user’s intentions or understand how a child feels. Protective settings may also differ between devices, accounts and apps. A child may encounter the same risks through another device, a web browser or a service not covered by the selected control.

Begin with the Free Parental Controls guides and review the actual functions a child can access. Use age appropriate accounts, keep adult passwords private and check privacy settings in each permitted service. If an older child has a legitimate reason to use a smartphone, consider restricting installations, public contact and unnecessary notifications. Technical protection should complement relationships, supervision and education, rather than replace them.

Recognising when a child may be struggling online

Children may not recognise that an online experience is harmful or may feel unable to explain it. Parents can look for changes from their child’s usual behaviour, especially when these follow online activities. No individual sign proves that online harm has occurred. Approach the child with curiosity and concern rather than accusations.

  • Uncharacteristic withdrawal, anxiety, anger or tearfulness after using a device.
  • Disrupted sleep, school attendance, appetite or enjoyment of offline activities.
  • Unexplained spending, secretive online contact or distress about messages and notifications.
  • Persistent worries about appearance, popularity, exclusion or the need to be constantly available.
  • A growing reliance on an AI companion or unknown online contact for reassurance.

How R U Doin Online?

Parents regularly ask children how school went or how they feel, but may not ask how an online experience made them feel. CODA’s #HowRUDoinOnline? approach encourages these conversations from early childhood through adolescence. Children who expect parents to blame them, punish them or confiscate a device may decide not to disclose a frightening experience. Make it clear that asking for help will not automatically lead to punishment.

Keep questions open and age appropriate. For example, ask what was enjoyable online, whether anything made the child feel uncomfortable, or whether anyone has asked them to keep a secret. Listen before giving a solution and explain any protective action you need to take. A child should know that their safety matters more than a rule they may have broken.

Practical family safety checklist

  • Agree to delay personal smartphones and social media throughout primary school. Discuss alternatives with other families.
  • Decide what the child actually needs from technology before providing access. Prioritise shared, supervised devices and age appropriate activities.
  • Use accurate birth dates and child accounts. Review permissions, purchases, location sharing, contacts and communication features.
  • Keep recreational devices out of bedrooms at night and protect time for sleep, physical activity and offline friendships.
  • Talk about personal information, unknown contacts, online pressure, scams and AI in language your child understands.
  • Agree who the child can approach if something happens. Revisit the agreement as their needs and maturity change.
  • For children who need additional support, adapt guidance, routines and communication to their abilities. Protect access to assistive technology and avoid one rule for every situation.

If you have already provided a smartphone, start with the current arrangements rather than blaming yourself or your child. Explain why you want to change them and agree reasonable steps, such as removing unsuitable apps, limiting private contact and establishing device free routines. Our Digital Wellbeing for Families guide provides further practical support.

Questions about online safety by age

When should I give my child a smartphone?

CODA recommends waiting until after primary school and delaying further wherever possible. Consider the actual need, the child’s maturity and available alternatives. A basic phone may meet communication needs without unrestricted internet access.

Should my child use social media at 13?

A minimum account age is not a recommendation to join. CODA encourages families to delay social media through adolescence when possible. An older teenager who eventually joins an eligible service still needs clear boundaries and ongoing support.

What if every other child seems to have a smartphone?

Acknowledge your child’s wish to belong. Speak with other parents, arrange alternative ways for children to meet and offer a basic phone if appropriate. Do not make access to a commercial platform the price of having friends.

Can my child play games without a smartphone?

Yes. A shared device or console can provide suitable entertainment, but review the individual game and its contact, spending and content features. Keep gameplay balanced with activities away from screens.

Can parental controls prevent grooming?

They may reduce opportunities for contact, but cannot guarantee protection. Teach children how to recognise secrecy, pressure and uncomfortable requests, and make it easy to disclose concerns.

What if my child has seen pornography or frightening content?

Respond calmly and avoid blaming them. Reassure the child, ask what happened without demanding explicit detail, and stop further exposure. Seek appropriate professional or safeguarding advice if distress persists or someone has deliberately exposed them to harmful material.

What if my child treats an AI chatbot as a friend?

Do not dismiss the feelings the child describes. Explain that the machine generates responses rather than experiencing care or affection. Discuss what the chatbot provides that the child feels is missing, encourage trusted human relationships and review access to the service. Seek professional help if there are serious wellbeing concerns.

What to do when something goes wrong

Stay calm, listen and reassure the child that telling you was the right decision. Stop harmful contact and focus on safety. If there is an immediate danger or risk to life in Ireland, call 112 or 999. Take threats of self harm seriously and seek urgent professional assistance when needed.

  • For suspected grooming, sexual exploitation, threats or other crime, contact An Garda Síochána. Keep relevant account names, links, dates and nonsexual messages where safe. Do not download, copy or forward sexual images of anyone under 18.
  • Use the service’s reporting tools and block contact where appropriate. For suspected illegal online content and intimate image abuse, consult Hotline.ie. A platform report does not replace a safeguarding or police response.
  • For financial blackmail, do not pay or send further images. Contact Gardaí and the bank if money or payment access is involved. If school related bullying occurs, discuss an appropriate response with the school.
  • Children and young people can also speak with Childline. Our Useful Helplines and Support Resources page provides further pathways. CODA’s contact form is for general enquiries and does not provide emergency assistance.
