As the majority of kids return to school this week, many will be with device in hand, likely causing a headache for parents - not just financially.
As we report today, cellphones and tablets are causing neck, hand, eye, ear and social problems.
Many schools have a bring-your-own device rule and screens are a crucial part of the curriculum. No one wants their child left behind, or to be the one parent fighting the status quo.
Health problems have developed slowly over time. Thirty-two years ago when New Zealand launched its first mobile network, we weren't to know how bad it would get.
Back then, we didn't spend even a fraction of our time staring at the small screen. There was no screen to look at. The first cellphones were more like giant portable landlines. We couldn't watch videos or talk to our mates on social media.
