This is the situation. From September DH will no longer be able to guarantee that he can be at school at 3 to pick up DD (10) and DS#2 (6) every day. He will probably only be 10 mins or so late. DS#2 (12) walks home from his school and is home by 3.30ish.
We are thinking about asking a neighbour who's DD is in DS#2's class to walk our youngest 2 home from school and then DD will have a key to let them both in. DS#2 and DH will both be there within 10 or 20 mins. So they will only be alone for a short period. I an accessible by phone and can always shoot home in an emergency, and they can contact the neighbour too if they have problems. Now, DH and I are happy that all will be well in that scenario. But are we doing anything technically illegal? I don't want to find that some concerned citizen has reported us to somebody
Any advice gratefully received.
