our local (small) shopping centre has a little playground for kids. Its outside, though still enclosed within the shopping centre, with cafe's n stuff around it for parents to sit.
The shopping centre is small - with just Woolies, fruit n veg, butcher and a few shops.
Dd (8) wants me to leave her there at the playground while I do my shopping.
If I just have to run in and get milk or bread etc, I do that ... but I havent if I will be longer than 5 minutes or so.
At what age do you think they are responsible enough to be left alone there?
