Nickname for a grandparent?

[Jods]

Josh's mother wants to be Mom-Mom but I have issues with that

I would too!! You are his Mom...

Both sets of our parents want to be called Grandma and Grandpa for Zoey I wish the both would have chosen something different

I've only known my grandmas because my grandpas died before I was born . Now I call my grandma, Grandma Lupe. I don't remember what I called my other grandma. She died of cancer when I was around 4 or so...

I always just called my grandparents by grandma/grandpa and their last name. my ex's nieces and nephews called his parents meemaw and pappy (or pappy dad). they called their great grandmother Beemaw, I don't remember what they called their great grandfather.
