DS1 is 9. He has a lot less freedom than I did at his age, but the world is a very different place now too.
He has no phone of his own, no tablet of his own - he's allowed to use mine when he wants to play a game but doesn't have unlimited access. We have no PS or Wii thing in the house - neither DH nor I are big into computer games, so we have never invested.
He's not allowed to walk to school by himself because we have a terribly busy main road between us and the school and I know he's still a dilly-daydream a lot of the time. Also, there's a move here in Aus (maybe just NSW) to prevent primary school children under a certain age walking to school unaccompanied - don't know how far that's going though. There have been several reports of children being approached in our area by unknowns in cars, so it's a bit of a hot issue here at the moment.
He doesn't play out because where we live, there's nowhere to do it - front of us is a busy main road, as mentioned and behind us is a narrow service road that people use as a cut-through - just not safe at all. But we have a big garden that he and DS2 play out in (gated and fenced). No, I wouldn't let him go out with friends on his own at this stage, but I have left him at home on his own for short periods because even though he's a dilly day-dream, he's also a sensible child and wouldn't do anything risky. Wouldn't leave him with DS2 though, that would be a recipe for disaster! DS2 is a very different prospect.
I expect I will let him have a phone when he goes to high school, not least because it might be one a bit of a distance and a train ride away; but I see no reason for him to need one until then. He's getting his own laptop for his 10th birthday, because he'll need it for school apart from anything else, but it will be locked up very tightly!
He's a happy, confident, outgoing child who isn't particularly nervous or anxious about anything, so I'm quite happy with the way things are going so far. But then, his peers don't do much different that I've noticed. It's a bit different here though, people are more widely spaced apart a lot of the time, unlike when I was a child and had 3 friends within a 2 minute walk!
