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?”.
i am not sure, but what i think i read somewhere is “ren” (as in pa"ren"t), so you would go like my ren dropped me to school or something.
That sounds cool too.
