Four grandchildren, two in UK about hour-and-a-half away, two in EU.
Two English: we grandparents travel over twice a week, pick them from school, take them home/to out-of-school activities, feed & bathe them, put them to bed and wait for one or more of their parents to get in from work, when we leave for our home. (In 'working from home' times we did the same, more or less, although they were in a different room in their house; we formed a 'childcare bubble' with them (and all got Covid, bit of a nightmare but we are through it now I hope).)
Other two, outside UK: we Skype five/six evenings a week, read bedtime stories/listen to them reading, then engage in 'virtual hugs'. Before Covid we travelled to stay with them four or five times a year in half-term/school hols, staying a few days/a long week; we look forward to doing this again.
Some holidays we spend together, siblings, grandparents, cousins. But also they spend time together without us, and holiday separately too.
All-in-all, I think we are lucky how we all get on within our distanced extended family, and that we retired people have the time, energy (and finances!) to engage the way we do. Grandchildren are the best thing in the world, as many of you are well aware. (Those grandparents with little or no contact with grandchildren miss so much, imo; us, we love spending time with these beautiful and interesting little people. We dote on them in the clichéd manner.)
