12 year old DS has a birthday coming up and has hinted that he would like a smartphone as apparently everyone in the universe has one except him. Currently he has a very basic mobile with no internet access. I am dubious about providing a child of this age with unfettered internet access, even though DS is very sensible and I think he can be trusted not to abuse the privelege. My questions are 1) does your teen/tween have a smartphone 2) if so how do you keep their usage safe? Thanks
