My GD's call me grandma, but our yougest GD calls my husband crappa, they come up with the darndest things.

My oldest GS called me Granna when he first started talking and it stuck.

Two oldest call me Gramma and youngest has always called me Mammaw. This is starting to change now that she is 4.

I am Grandma Honey to my grandkids, and my mother is Grammy. She used to be Apple Grandma, when she still had the orchard from which they made their living. My great grandmother was Grandma Havre--that is where she lived. And my dad's mother was Cookie Grandma--because she always had cookies on hand when we came to visit.

I'm called gma by oldest grson, gramma Jill by youngest and
Jillith by stepgrkids. So depending where I'm at, is what my name is. Getting to be this old, (62) it's sometimes hard to remember what my real name is. lol

I have only heard of one other person who is gma, my sister. She was given this name by her oldest granddaughter. And grandpa is gpa of course.

We called our Grandmother Gra.

My children call my mommy Nana,, my rothers children call her grammy,,,,

My GGM is GranGran because my oldest could not say GGm.
My Mom is Grandmommy.
I was Momymom till they hit their teen years. Now I'm just Mom. No GKS yet.
