this was discussed on a thread a few months ago (obviously not this news story, the topic) and we all had massively diferent ideas. I walked to school alone from what would now be Yr 1 having been walked to school by bigger sister for Reception and then I in turn walked my littler sister to school when I was Yr 3 and she was in reception. This was up the road less than a mile crossing 3 roads one big enough for a bus to travel along the others tiny ones. At 7 (so year 3) I walked with my bigger sister to my junior school which was much further probably 1 and a half miles maybe? About 5 roads, one of which was a main road, really busy. But this was in the 1960s and life was so different then, fewer cars definitely and we lived somewhere where everybody looked out for you. Not many mums worked of course then (my mum secretly cleaned people's houses to get extra dosh and LOCKED the 4 of us in a small bedroom when she went to work in the holidays, leaving the biggest sister in charge, oh those were the days indeed!!).
Now I would love to send my 8 year old (yr 3) alone to school but it's too far (1.5 miles) along unpaved country road and big roads very busy at the bottom of the hill into the village. The school doesn't have a policy but won't allow kids under yr 6 to cycle alone to school even so guess they would take a dim view of me sending her alone! Having said that , loads of kids do walk within the village and sometimes I raise an eyebrow at the little ones on the crossing alone. But we all have to look out for them, it takes a village to raise a child and all that?
