What's in a name?

I am Gran to our wee GD, the same as my mum is to her GD's ... she has become great Gran to her two GGC but has recently wondered if she should become Grandma. We had 2 (great) grandmas as kids and so I associate it with really old ladies.
I was amazed when a young friend told me her mum (a slip of a girl in her 40's at the time) was called Grandma!

My mums first name is Nana, so for our family it's not an option. ?

I'm a different name to different grandchildren when the older ones were little it was Nanny now they are grown its granny to most of them or just Nan, to the little one who lives abroad I'm granny and to my first Great grandson just Nanny. I answer to anything as long as its not a swear word

Well I'm grandma(because that's what I am,a grandmother) and I have to say very proud and happy to be.My dear dear sister died 6weeks before here first grandchild was born.

phizz congratulations it must be lovely having a baby around to cuddle. My youngest is now 11 he calls me Nanna (I called my GS Nanna and I prefer this to Grandma) and his paternal GS Grandma his step GS Grandma Chris. My other GC's call me Nanna and then my first name as they have a couple of other grandmothers too. Confusion for children when we have these 'blended families'.

Thank you for all your suggestions. I rather think I like 'Gaga'..the most apt.

However, knowing children as I do, perhaps the little one will have his own ideas as to what name suits me.

I cannot wait to find out.

Great grandma?

I don't understand why you can't be called by your name eg grandma Sophie.

In our family we use the Yiddush word for grandma which is Bubba and I grew up with a Bubba Goldie, a Bubba Sophie and Bubba Brownie.
My grandchildren have both their grandmas and a great grandma, for example, so their great grandmother is called Bubba Dudu.

I'm nannie and my mum was grannies.
I do like the idea of grandma for GG but DGS found it a bit of a mouthful

I like GG. My GG died when I was little, but we just called her Granny Mc***, the same as mh grandmother. My great aunts were just Auntie *. It would be nice to have something special for great gran though and GG sounds fun. Not sure about great aunts.

My grandfather became known as 'old granddad' when his first great grandchild came along. He loved it - if we get that far not so sure it's for DH. .

In our situation it is complicated by two languages being involved. On our side, the English-speaking side, my father insisted that my children called him by his Christian name, and I think my mother would be quite all right with her great-grandchildren using her Christian name, if she's still around when the little ones can speak enough.

I can't imagine that little ones would grasp the concept of "great-granny" so perhaps just granny or granny and your Christian name might be a good compromise.

How about "Grandmama" = full of age and wisdom but not terrifying (unless you want it to be) to a youngster.

It depends what names for a grandma are already taken, and what your DGC call you I suppose.
Our DC called their DGG 'Gran'

I am just 'Aunty ***' to my many great-nieces and great-nephews.
I am a great-great-aunt too, now that must make me old

You called, Ana?

My mother was always known as GG to the great grandchildren.

Gaga?

How about Geegee (for great gran?)
I recently became a great auntie and that one is perplexing me ha ha.

Well obviously I favour Nana :-)
