I don't know. Not until they are responsible enough to understand it properly. Just being their friends on there doesn't help you keep an eye on their account, you'd have to have their login. There's too many ways to hide stuff on your feeds, like lists and private groups. It's in the too hard basket for me... will think about it when they reach teenage years I guess! I don't think we're the types to ban it tho, we're all for educating our kids how to use the internet and do it safely.

I know someone who checks their son's phone bills and asks about numbers they don't recognise. I said to them 'you do realise that most people text each other over IM apps, so the phone bill isn't a reliable way of seeing who they're texting'. She obviously hadn't thought of that, and looked a bit freaked out!
