A lot of what Susie says is true, MzOops moved from Central London down to Cornwall, there is a school bus, but it stops at a nearby village so she has to drive them to the bus stop.
Admittedly they live in the middle of nowhere, a river over the lane, their own woodlands and they had an amazing childhood there.
Now they are teenagers it isn’t so good, one of the children has just gone to University and loves the town life, the other is at 6th form College and misses his mates that he can only see at weekends if my daughter takes him into town and then collects him, which isn’t always convenient. MzOops found working from home fine and is always busy either online or doing her many voluntary jobs.
We’ve always lived in the countryside and it certainly has its pluses but when the children are older it gets more difficult and nowadays more expensive., when ours were aged 13 and 11 we moved back (briefly) to our small market town, then moved back into the Countryside when they left school and had their own cars.
I imagine if your family are moving to a Village it will have buses and won’t be far away from a railway station, I’m sure they will love it and they will certainly be away from dangerous pollutants which is a big worry for young children and you will have a lovely place to stay when you go to visit.
