I look back now at how I was with my parents/ in laws. They were great at helping with childcare etc. Perfect grandparents. Sadly my parents both died when I was in my 30s so my own kids were still quite young. My in laws lived well into their 90s. We continued to visit on a weekly basis..but they wrre reasonably close for a coupleof hours on a Sunday etc. If they had been further away more difficult to do. The kids did not visit as older teens/ young women except on birthdays/ Christmas etc. I think distance is key.
