Our 2 DGDs live about 1 hour away by car. We see them every few weeks as they are both at school now and do a lot at weekends. We always see them for birthdays and we are together somewhere, their house, our house, Auntiy's house or rented cottage, at Christmas. We also all go away together in the spring or summer.
Besides that they come to stay on their own and get spoiled.
So sad I’ve nearly finished last Jilly Cooper

GS1 4 days a week after school, GS2 ditto after pre school, and GS3 probably a couple of times a week.
