10 year old DS has been cycling home from school (on his own or with a friend) since last September. The route is through a residential area with few roads to cross (no main roads). The route is all on off-road cycle paths except the very last bit up to our house, where he tends to cycle on the pavement.
8 year old DD normally goes home with a neighbour.
One day next week the neighbour can't collect DD. A friend who often collects is also busy. DH (who works at home and normally will pop out for stuff like this) has a very important call at school run time (his words) and can't either.
DH thinks we should just let DD cycle home with DS. I am slightly uneasy about this, but not sure why except that she has never done it before and we wouldn't let DS do it until he was older. She is sensible and used to cycling the route; DS has a mobile phone if necessary.
So AIBU (or WIBU rather) to let DD come home with DS without an adult?
