My mum wants her “grandmother name” to be GRANDMUM.
I really don’t like it - I feel like she’s deliberately wanting to use the word “mum” in it to try to take over from me being the mum - there should only be one mum and that’s me imo! (Yes that is the kind of childish thing she’d do).
Its also clunky to pronounce and I don’t know why she can’t just use Granny or Grandma or whatever.
If I say anything to her she’ll probably have a meltdown, but AIBU to not use it myself to the kids and just say “Grandma”?
