So my parents split when in was 5 ..however dad has always been apart of my life.
He met his partner when I was 9 and she had 4 kids ( I was the youngest of all the kids )
Her eldest son 3 yes ago had a daughter and they asked my dad if her daughter could call him grandad as she his dad wasn't around neither was the mums and my dad had been around for the last 10 years or so - this wasn't an issue.
Fast forward 3 yes I have a lil girl and the whole thing of her calling dads girlfriend gran has come up...now my daughter has a gran my mum who loves her v much. She is very offended about her being called gran as she isn't my daughters gran and she is.
Step mum has been OK , I don't dislike her she has done some really nice things for us but has never really included us as an whole family it was a bit like my dad,her and her kids and then my dad and us.
But she has been quite supportive whilst daughter has been sick and gave us some money.
So dad wants her to be called gran like he is to her grandaughter but my mum doesnt .
