TIGHTLY around roads.

Even if you think they're mature enough to walk along without, they can really take you by surprise. Once I was walking through town with the little ones I nanny for. They were around 4 and 6 at the time. The little girl dropped some crappy leaflet she'd picked up at the library, pulled her hand out of mine and dove after it - straight in front of a car!! Thank goodness it stopped in time. When I exclaimed that she could have been run over her older brother defended her with 'But if she hadn't the LEAFLET would have been run over!'
I hate seeing young children walking independently, or using scooters or bikes along pavements. They just don't have the road sense. It's not worth the risk.
