A trans parent would likely still want to be called “Mom” or “Dad”, I assume. At least that’s the case with the few trans parents I know.
Parents don’t usually use “daughter” or “son” as pronouns, so I don’t think it would come up with non-binary children.
Do children of non-binary parents call their parents by their first name? It seems unlikely that they say “Parent, may I please have more screen time?”.
and what about enby grandparents?
Sure, same idea.
Grandy seems an easy choice.
My aunt was raised by her grandfather and called him Grandy. Everyone has called him that since.
I was wondering the other day why gran is always the grandma not the grandpa
I would expect it’s a shortening of “granny” not grandma (or grandmother) directly.
