When I was a child there weren't many options for entertainment after school or on weekends: I could walk to a friend's house. I could watch TV on our 13 fuzzy channels. Or I could read. And so I read, and read, and read -- hours and even whole days would pass with no interruptions. I didn't have any choice but to concentrate.

The countdown makes me gasp every time. Ten seconds until the next episode of whatever show my daughter is watching. Nine seconds. Eight. Seven. Six.

There are a lot of numbers you have to keep in mind when you're raising a kid: Their height and weight. How many millilitres of milk they're drinking, at first, and then how many fruits and veggies they're eating, how much outdoor play they're getting, and of course, how many minutes a day they spend glued to a device.

Parents (understandably) don't want their kids to watch mindless drivel or disturbing cartoons. A redesigned YouTube Kids gives them more control.

Smartphones are a part of life these days, and if your kid doesn't use one now, they probably will before long. But with a great device comes great responsibility. The Smart Talk is a website that helps parents and kids come up with a set of phone rules together, and creates a handy agreement you can print out.

Not long ago, paediatricians recommended limiting the amount of time kids spend on phones and tablets to just one or two hours a day, with toddlers getting none at all. That has changed, and now parents are supposed to make sure kids have a healthy relationship with their devices. Where do you begin? Here are a few ways to approach the task.
