Step daughter having a baby

[FiremanKing]

My oldest step daughter is having a baby.

My husband will be called Grandad and her mother will be Nanny and her husbands mother will also be called Nanny.

But my husbands ex wife has specifically mentioned to her daughter that I should not be addressed as Nanny or any other grandparent name (granny, gran, grandma etc).

My husband says this is nonsense and I can be Nanny too.

My step daughter and her husband think I should be called Nanny too but my step daughter has said her mother is going on and on about it and it’s causing a lot of tension.

The other Nanny to be, the mother of my step daughters husband has no problem with my being called Nanny.

I would love to be a third Nanny but I don’t want this to mar the arrival of the new baby.

What do other step grandparents call themselves?

I have no memory of my grandad and nan together. He has been with a lady called Pat ( lovely lady ) for years. They've always been grandad and pat to me as my parents called them that. I had 2 nannies. She wrote in my kids card once great nanny and grandad ( my nan passed away 20 years ago ) I didn't like it even tho my kids will have no memory of my nan. I know you will like it but I think it's respectful to the actual grandmother. I love Pat she's amazing no idea how she puts up with my grandad.
