What did you call your grandparents growing up?

I only had one, my Mom's father. I called him Papa.

Nanna and Poppa for both sides when with them. Talking about them, it was Nanna (Their name) and Poppa (Their name).

Grandma and granddad same for both sides of the family but like yourself I only had one granddad my dad's dad had diеd before I was born..

I seem to remember my grandma on my dad's side would be referred to as grandma followed by the family surname if there was ever any reason to specify which grandma it was.

I called all of them Grandma and Grandpa, and GREAT Grandma and Great Grandpa. I actually met and knew a couple of my "Greats". It's an American Midwestern thing.

grandma and grandpa i was only close to my dad's side of the family tho my mom's side were snobs

Dads side: Grandma and Grandpa

Mom's side: Grandmother and Grandfather

My grandfather died when I was 3 so I didn't really get to call him anything I just remember staring at him a lot. But I called my grandma "Mommy"
