Be part of their life is the best thing you can do, we have been made the drive to Ames for T ball games and music concerts 4 times in the last couple of months. We try to see the close two at least once a month if not more.
The other two we do zoom calls with them every couple of weeks. We are leaving tomorrow for S. Carolina to spend the week with them, its hard to see them when they are 15 hours away.
We have had grandkids week for the past couple of years, before the boy moved, took all four during the week to our house, gave their parents a break.
Holidays are a pain, our plan is simple, do not care when all three of you are home, but I want you here all that the same time. The weekend before Christmas, after Christmas I could care less, I also tell them that their kids should be at home on Christmas day, enjoying their toys.
