This informal CPD article ‘Growing Up Online: What Every Family Should Know About Children's Rights in the Digital Age’ was provided by Cima Care, who offer extensive training in vaccination and public health, advancing global health initiatives.
A child born today opens their eyes in a world woven from screens, signals, and algorithms. Within days, a text message may already be reminding a family about an upcoming vaccination. By the time that child takes their first steps, a voice assistant may be answering their earliest questions. Long before children fully understand the digital world around them, that world is already shaping their health, safety, and sense of identity. Understanding what this means — and how families, health systems, and policymakers can respond — has become one of the most pressing questions in child wellbeing today.
An Old Promise, Applied to a New World
A landmark international treaty on children's rights was adopted in 1989, long before smartphones or social media existed. Yet its core promise — that every child has a right to health, safety, education, and a voice in issues that affect them — now has to stretch to cover a digital reality its authors could never have suspected.
In 2021, an authoritative international clarification confirmed that every right children hold offline must also be respected, protected, and fulfilled online — including privacy, safety from harm, access to reliable information, and the highest attainable standard of health. Research consistently shows, however, that putting these principles into practice still lags behind the rapid expansion of children's digital lives. (1-3)
Two Faces of the Same Coin: Opportunity and Risk
Today's digital environment is something of a paradox. It offers children genuine opportunities for learning, connection, and creativity while exposing them to real risks, including privacy concerns and harmful content. (4-6) Because of this duality, protecting children online cannot fall solely to parents; it requires shared effort across governments, technology companies, schools, and health systems. (7)
A Digital Divide That Is Also a Rights Divide
As of 2024, over 95% of people in high-income countries are connected to the internet, compared with only about 26% in low-income countries. Because the world's youngest populations are growing fastest precisely where connectivity is weakest, particularly across sub-Saharan Africa, this gap threatens to deepen existing inequalities in health, education, and protection. (8-9) This is not simply a technical issue. When healthcare systems lack adequate digital infrastructure, care becomes more fragmented and harder to coordinate — and the children who need it most are often the ones left without it. (10)
Encouragingly, a 2025 systematic review across 19 sub-Saharan African countries found that text messages, voice calls, and mobile apps were generally associated with improved childhood vaccination coverage and timeliness, with voice-based tools appearing particularly promising. (11) Similarly, a 2021 meta-analysis found that simple text reminders significantly increased childhood immunisation coverage and timeliness, with the strongest effects in lower-income countries. (12)
The Global Rulebook: Four Principles for a Child-Safe Digital World
International guidance sets out four core principles that should shape any digital development, service, or policy connecting a child's life:
- Non-discrimination — every child should benefit from digital opportunities equally, regardless of income, language, ability, gender, or location.
- Best interests of the child — design and policy decisions should place children's wellbeing above commercial interests.
- Right to life, survival, and development — digital systems should support, not undermine, children's growth.
- Respect for the child's views — children deserve a voice in shaping the digital environments that affect them. (13)
On privacy, particularly, guidance encourages families to keep devices updated, review privacy settings, limit app permissions, and talk openly with children about their digital footprint — framed as building digital literacy rather than restrictive rules. The same guidance calls on developers to collect only the data necessary for a clearly defined purpose and to build privacy from the outset. (14)
A Growing Mental Health Signal
A large-scale regional survey, drawing on responses from almost 280,000 adolescents across 44 countries, found that problematic social media use increased from 7% in 2018 to 11% in 2022, with girls reporting notably higher rates than boys (13% versus 9%). (15) Global estimates suggest that roughly 1 in 7 adolescents aged 10 to 19 lives with a diagnosable mental health condition. (13, 16-17)
Because a child's right to health includes mental health, parents and healthcare workers are often the first to notice warning signs — social isolation, changes in sleep or appetite, or unusual secrecy about digital activity — and the most effective response is calm, open conversation paired with practical support, rather than alarm or punishment. (18)
AI may shape how children learn
When Artificial Intelligence Joins the Family
Children increasingly encounter artificial intelligence through games, voice assistants, and AI chatbots. Experts have noted that AI risks often extend beyond privacy or manipulative design — they also concern how AI may shape how children learn and form relationships. An endlessly agreeable AI can create unrealistic expectations of friendship, while overreliance on AI for answers can erode the productive effort that supports deep learning. (19-22)
Warning signs of unhealthy AI use include unusually long sessions, distress when asked to stop, secrecy, and AI time crowding out sleep or schoolwork. As with social media, the recommended response is conversation rather than restriction — staying curious, asking how it makes children feel, and setting shared expectations as a family. (19-23)
Cyberbullying: Permanent, Public, and Often Faceless
Cyberbullying differs from traditional bullying in that it can be widely visible, permanently stored, and sometimes anonymous. Adolescents who experience it report higher rates of depression, anxiety, loneliness, and suicidal thoughts. (18, 24-26) Experts recommend a non-judgmental approach: listen first, document what has happened, and use platform tools such as muting and reporting rather than reacting in anger. Both targets and bystanders need to know that the adults they confide in will respond calmly and constructively. (27)
Where Children's Rights Begin: Digital Health From Infancy
Long before a child owns a smartphone, the digital environment is already shaping their right to health. Digitally enabled health systems are associated with improved quality of care, more accurate real-time data, fewer medical errors, and more efficient frontline services. (28, 30-31)
The scale of the remaining challenge is significant: globally, full childhood vaccination coverage still falls well short of established international targets, with the widest gaps consistently found in conflict-affected, remote, and under-resourced settings. (32) The evidence converges on a some key insights: digital health tools for children typically work best when they are evidence-based, well-integrated into existing systems, equity-focused, and built around the needs of families. (11, 28, 30-32)
What the Evidence Tells Us: A Practical Summary
Bringing together international guidance and recent peer-reviewed research, several principles emerge:
- Start from rights, not fear — the digital world should be made safe and beneficial, not simply avoided. (13)
- Simple reminders work — text reminders meaningfully increase childhood immunisation coverage and timeliness, especially in lower-income settings. (12)
- Voice tools can help further in lower-literacy contexts, with several studies suggesting larger vaccination gains when voice components are included. (11)
- Minimize data, not maximise it — digital health and parenting tools should collect only what is necessary for a defined purpose. (14, 33)
- Treat the family as a unit — guidance works best when it speaks to parents and caregivers together, especially during stressful periods. (4)
- Start conversations early, and keep having them about AI, privacy, online safety, and cyberbullying. (4, 14, 18)
- Keep monitoring and adapting — real-time tracking of coverage gaps and emerging risks helps systems and families adapt as the digital environment evolves. (10)
Children's digital rights are not realised in the abstract. They are realised in a text message reminding a parent of a child's next vaccination, in a conversation between a parent and child about an AI chatbot, and in a healthcare worker who notices a warning sign and responds with calm support rather than alarm. (29)
As children's lives become increasingly intertwined with digital technology from their earliest days, ensuring that this environment serves their health, safety, and development — rather than undermining it — remains a shared responsibility across families, health systems, and policymakers alike.
