At what age did your parents become grandparents?

[~clover~]

My mum became a grandparent at 36 and my dad was 35.

I was starting to feel like the only one!

My parents were both 36, MIL was also 36 & FIL 37.

My paternal grandma, who's now passed, was 60 when she became a great grandmother. My paternal pop was 71, is now 82. My maternal grandma was 68 or 69... she's 80 now. Never knew my maternal grandfather.

If they keep going the way they are they might be around to meet the first great-great grandchild!
