Here's the thing - my 8 (nearly 9) year old is used to playing out on the green in front of our house (which he has to cross a very quiet road to get to) pretty much by himself, but the key issue is I could always see him from my front room window/front door...
so we've moved - about 50 yards away but so that there's still slightly more road to navigate (the same quiet road), round a corner and there is no direct view over the green, although I can see a corner of it from my bedroom.
He is mostly quite sensible and knows about road safety (after a fashion - I wouldn't trust him on any 'proper' roads yet) and stranger danger... I also feel he is ready to be trusted a bit more to allowed a longer leash
Few strangers other than the people who live on this green ever go past, though there are some and most of the cars drive very slowly (is a cul-de-sac).
So when he wants to play out, do I just let him even though I can't see him? Or is it too young...? Or somewhere in the middle (ask him to check in every 20 mins or so? use walkie-talkies!? some other genius solution I haven't thought of?)
Or just stop fretting and be happy he can play out freely...?
Would be interested to know how other parents handle this kind of stuff
