Wondering how to refer to my sister's daughter now?

[LoveMyPiano]

I always referred to her as my niece - but she is going into a sort of non-gender stage..... Her name is a very neutral one now. But I still cannot stop referring to her (them??) as my niece. Relation/ships are usually gender specific, and a bit hard to avoid using I have found, but I really don't want to offend. It is the "non-gender" bit that is causing me some difficulty.
Help......

female isn’t a construct. Gender neutral means she is simultaneously asking you to know what a girl is and also lie that she isn’t at the same time

GenZ women have not experienced what boomer women and Gen x women have seen and experienced. Ironically it’s probably TRAs that will bring this to the attention of GenZ, therefore the movement will be self limiting.

My own Gen Z DDs and their friends no longer accept the dictates of their gender obsessed peers. It's already becoming uncool to have different flavors of gender fluidity. They got fed up with the sanctimony and the mockery (Dylan Mulvaney peaked them).

Teenagers have more social power with peers than mothers, so if regular kids are turning their backs on the nonsense, the social contagion loses oxygen.

My only fear is ostracized vulnerable girls who need healthy friends, not glitter families. But it's hard to be friends with someone who's is constantly finding fault with your language and your reactions.

Just searched the Merriam Webster dictionary and no mention of the word 'nibling' nor 'niebling' nor 'neibling'. If it's been in use since 1950, someone should tell the good people at Merriam Webster.

I love the word Nibling. I use it to refer to my Nieces and Nephews collectively.

Could you say "my sisters eldest/youngest"?

You ought to spend some time with your niece, because you seem to say you don’t yet you seem to need to accommodate...

I smell a rat.

Also spending time with her, if in fact this is real and you have a genuine concern, may allow her to get off online echo chambers that are possibly shaping her confusion daily 24/7

Despite that making it into an anecdote, it still doesn't show up in the search.

It's like fetch. Some people are trying so hard to make it happen, but it's still not going to happen.

Fetch?

@FaceLikeCattle you need to watch Mean Girls 😉

I don't know why you "smell a rat". But I can see why it is confusing, without going into the whole strange family situation.

This is not a way that I wish to refer to her should I be in her company, but how I might refer to her when NOT, if you understand.....? It is also tricky given that she is using a different and very gender non-specific name now.

The conversations would be with the OTHER side of the family - who don't know her, and who would also have difficulty with the subject - their ages in part, and also their religious beliefs.

It is a difficult "family" situation anyway - and this is another complication.
I have also learnt a lot through the replies and comments though.

And plan to stick with her name given at birth 🤗when referring to her (no matter who I am talking to), but use her new one if I am speaking to her, or her close family, which is pretty unlikely anyway 😥

I agree.
