We are Grandma and Grandpa (DH is stepdad to my sons but kids don't care), DIL parents are Nana and Zeyda, and my ex and wife are Pops and Grand JoAnn. Seems like we all picked our names and no one objected. I've heard Bubba, Bubbie, Meemaw, Mawmaw, Mimi, MaMA (accent on last MA) Ganny, Granny, etc. One of my friend's grandchildren call her Blondie!! Let us know what gets decided!
