Hi just one grandchild, he’s 11, they live in Hertfordshire and it takes over 1.25 hrs on a good day, yes it would be lovely to live closer, but it’s not the ends of the earth.
My elder son lives in Bristol and has no intention of ever moving back to Essex and if he ever starts a family (unlikely) we will be 5 hours away by car.
Our other two daughters are looking to buy their first properties locally, so if they have children (they are both lesbians) we will be close by.
Tbh, I’m just grateful my children live in this country not in Australia or NZ!
