To help parents navigate children's screen time, French psychiatrist Serge Tisseron developed the 3-6-9-12 rule, which is now widely used as a practical guide for introducing children to the digital world. Rather than offering a rigid set of rules that applies to every family, it provides simple milestones to help children gradually develop healthy digital habits.
Before the age of 3, whenever possible, experts recommend avoiding screen exposure altogether. At this age, young children need to discover the world through their senses, movement and interactions with the people around them. A familiar face, a comforting voice, building blocks or a walk outside contribute far more to their development than a screen - even one marketed as educational.
Before the age of 6, screens are best introduced as a shared activity with an adult. During these early years, children continue to develop their imagination, motor skills and social abilities through free play, creative activities and everyday interactions with others.
Before the age of 9, non-educational access to the internet and video game consoles is generally not recommended. Young children are not yet equipped to distinguish reliable information from inappropriate content or to fully understand how the online world works. At this stage, it's best to prioritise educational content and ensure that screen use remains supervised.
Before the age of 12, Internet access and social media should still be closely supervised. While these platforms naturally become more appealing as children grow older, they can also expose them to distressing content, privacy risks and social pressures that are difficult to navigate at this age.
These milestones remind us of one essential idea: digital independence is something children learn gradually, just like learning to read or ride a bike. As they grow, they can enjoy more freedom - but that freedom should always come with guidance, support and age-appropriate learning.
