My DS aged 5 plays out on our driveway/hedgrow/up the path and slighlty out of sight all the time.
He will literally play out with friends all day, riding bikes, climbing trees etc
Not allowed to cross roads yet though and contant chats about stranger danger etc.
My Ds aged 7 is allowed across the road, but I have to know who he is with, where he is going and I also spy on him from time tio time to make sure he crosses the road carefully.
My dds aged 10 (twins) are allowed to the play park with riends but they must have a phone with them and we agree on strict times to return home.
I worry about my children all the time (naturally) especially as we had a horrible experience last week with a neighbour but I force myslef to allow them their freedom and independence because it is so important (but obviously within limits)
I feel much happier and more relaxed when they are all in, fed, bathed and on the sofa
As a child I lived in hastings and at the age of 8, I would catch the bus on my own to the White Rock Pavillion Swimming Baths and go for a swim, then catch the bus home. Never bothered me. Times have changed since then, alhough actually they haven't really!!!!
