Kids & Smarphones

As late as possible, probably when they're in primary school - but even then I'd just give my son a normal functioning phone, as long as it can SMS and call it's good enough. I personally feel that they don't need smartphones at all, more often than not, it is for the convenience of adults and very bad for their health in so many ways - my son had a period that I call smartphone addiction, he was down with fever but spent 10+ hours watching YouTube without eating/drinking. That was when I drew the line with my parents on smartphone usage and put him in "rehab" haha, it took over 3 weeks to finally get him without thinking about it - but of course, it also meant that we had to play with him more!
