Cutting long story short, I gave them all the choice when I had ds of grandparent names my mum and dad are grandma and grandad and exp's were granny and grandad which was fine, their decision.
However, one of my ds's first words was grandma (or mamar lol) and since then I've noticed her referring to herself as his grandma!
I'm confused should she be allowed to just change her name as she pleases, my ds is 2 in a month and all his baby books, photo albums refer to her as granny as thats what she wanted to be!
AIB really petty that this annoys me? I obviously know it makes no difference in the long term but still............
