Do your children have grandparents/great-grandparents still living?
My sons are 7 and 10. I'm 36. I'm lucky enough to (still) have two grandparents (Dad's mum, nearly 90, and Mum's dad, 86) still living. And, importantly for the boys, they are still active. Both of them have travelled from Canberra to Melbourne this weekend to attend my nephew's Baptism.
Grandma has four great-grandsons (10, 7, 2, newborn) and three great-granddaughters (4, 4, 2). Not bad for a 90 year old.
Granddad has six great-grandsons (10, 8, 7, 6, 2 and newborn) and three great-granddaughters (13, 11 and 2). Not bad for an 86 year old.
I think with the aging population, our children are more likely to have great-grandparents still living, however with the increased maternal ages (generality of course) it's more likely that people in their 70s and 80s are just becoming grandparents. At my boys' school, most parents of the 10yos are in their mid-late 40s, so the grandparents would be at least in their mid-late 60s, (but mostly 70s) so great-grandparents are incredibly rare.
Are you lucky enough to still have grandparents? Do your children have great-grandparents? How old are they?
