It started as something innocent. I wanted to understand what my daughter actually looked like when she was using her tablet, so one afternoon I propped my phone up on the shelf across the room and hit record. Then I left her to it.
When I watched the footage back that evening, I felt genuinely uncomfortable. Within about four minutes, she had slid down the sofa cushion, tucked her chin into her chest, and brought the screen about 20 centimetres from her face. She stayed like that — almost completely still, head dropped forward — for the better part of an hour.
I showed my wife. Neither of us said anything for a moment.
Forward head posture — sometimes called "tech neck" — is increasingly being studied in children. For every inch the head moves forward of the shoulders, it effectively doubles the load on the cervical spine. At a full 15-degree forward tilt, the neck is managing the equivalent of a 12-kilogram weight. At 60 degrees, that's closer to 27 kilograms. In a child whose spine is still developing, that kind of sustained pressure isn't trivial.
A 2020 study published in the European Spine Journal found that children who used hand-held devices for more than two hours daily were significantly more likely to report neck and shoulder pain compared to those who used them less. The researchers noted that the combination of sustained posture and screen proximity was particularly concerning for long-term musculoskeletal development.
My daughter was seven at the time. She'd never complained of neck pain. But kids rarely do — they're flexible, they bounce back, and they don't connect the dots between how they sit and how they feel. It's the cumulative effect that worries me. Ten years of that posture, a few hours a day, across the formative years of spinal development.
We made some practical changes after that. We mounted a small tablet stand on her desk so the screen sits at eye level. We set a timer so there's a movement break every 30 minutes. And we talked to her about it — not in a scary way, just showing her the video and asking what she noticed. She was surprised. Kids often are when they see themselves from the outside.
I'm not anti-screen. I know that's not realistic, and honestly it's not what I believe either. Technology is part of their world. But how they use it — the posture, the distance, the duration — those details matter more than I'd ever stopped to think about. The one-hour video made it real in a way that no article ever had.
Try it sometime. Film your child from across the room for twenty minutes and watch it back. It's one of the most useful things I've done as a parent.
