My DD1 is 9 years old and in year 5. This is the year in which pupils are allowed to walk to or from school unaccompanied and DD1 is keen to do that. It's only a 15 minute walk, but I'm uneasy about it, as there is a busy road to cross. There is a lollipop lady who helps the children cross the road, obviously, but I'm not totally sure I can trust her not to cross the road earlier if she sees a friend on the other side. In addition, she does other silly things, like climbing onto a wall and walking along it.
Admittedly, she'll be less likely to do things like that if DD2 (6) isn't with her. But she is quite young for her age emotionally, and has some SEN that we're getting her help with, as well as Attachment Disorder as a result of being adopted.
But it's encouraging that she's keen and she obviously needs to start walking to and from school herself at some point. It would be interesting to know at what age other parents on here allow their DC to go on their own.
I used to walk to and from school at much younger age, but obviously roads were less busy in those days.
It wouldn't be all that often, as I will be taking DD2 to school anyway.
