My kids don't have access to one set of grandparents. Their other Nana & Pop like 4000kms away and they are lucky to see them once a year. It worries me for all the reasons you say, but I'm lucky I guess because they have lots of "Aunties" and "Uncles" who love them and spoil them, and hug them. It's why we try and see their godparents once a week.

My situation was similar to yours. My grandparents I remember from when I was little, but then we moved away, my parents cut contact with them at one point and I made contact myself when I was older. Didn't turn out that awesomely because I think they just didn't understand or know me. A lot of baggage and dirty water under the bridge iykwim? My other grandparents one died before my own parent could get to know them and the other was sick and quite invalid by the time I was born, and then died when I was a child.

I'll be honest and say I missed exactly what you are talking about, but at the same time I'm grateful for the few things I learnt from them and maybe if I had been around them more often I might have taken that for granted as others do. But I also look at the amount of love and support and spoiling I give my own children. Things are very different today, and when I was a child my parents didn't have that to give and I'd say I do more with my kids than my friends grandparents did with them. I think things are changing, maybe because our parents generation was very different grandparents seemed to substitute what our parents couldn't give or couldn't do. I also make a point of sharing stories about my families down the line so they will have that sense of heritage iykwim?
