I called my mom's mom grandma brown and ever since everyone calls her that. I was the first grandchild so I guess I picked the name out. I called her grandma brown cause when I was little I had so many grandparents it was hard to remember names. And since shes native american her skin is brown so I would call her grandma brown. Lol :) In my family we usually call grandparents by grandma/grandpa with their first name afterwards. Like grandma dee. But the grandpas are papa. Like papa tim or papa al. My mom hasnt said she doesnt want to be called grandma or anything. So hopefully it wont be a problem. :) oh yeah we also call one of our grandmas mormor too!
My kids call my grandmother (who we all very close too) Nannie, my husbands mom is Meemaw, & my mom started out as Grandma but when my daughter was old enough to say it she would tell us no she's Grandmom so now that's what all my kids call her.
My mom didnt wanna be called grandma either so my brother's daughter called her Mimi and it stuck. My dad is Pop Pop.
I grew up calling my moms mom "granny goose" and somehow all my other cousins adopted it too lol. My dad is Swedish, his parents I called Farfar and Farmor, Swedish for fathers father and fathers mother. My mom wants I be Mormor, mothers mother, but my dad doesn't know if he likes Morfar... Lol. I told he can choose or we are going to find something outrageous to call him, like grampy or pappy lol!
When we started having grandchildren we wanted our grandkids to be able to know us from the other grand parents. So we are Opa & Oma which is german for grandpa & grandma:)
Im calling my mom grandma and my grandmother will be nanna
