Parental Filter

There are some very original names that grandkids call their grandparents. Some sound REALLY original!
Anyway, it had always had been a joke with our kids that I wanted to be called "Grandmama" like Endora on Bewitched. It always used to get my daughter's goat. She'd swear I'd better find another name because her kids wouldn't be calling me that.
When our oldest granddaughter was born, the first thing my daughter said to me was "Hi, Grandmama!"
Our granddaughter was a very early talker and she pronounced "Grandmama" right off. Her little brother pronounces it "Gum-mama". Our son's oldest son never can decided when he's finished, because he calls me "Granmamamama..."
I answer to all of them.

When I was a child both grandmothers of a friend of mine were called 'granny' to distinguish between them she called the larger grandmother Granny grew.

When the time comes, if my daughter ever makes me a grandmother, I think I'd like to be "Nana" or "Memaw." What *she* calls my parents is Grandma (or more like "Grammaw" actually) and PawPaw.
