My autistic 13yo DD identifying as gender fluid. Need help to navigate this

Oops typo mistake too i should have said...

I see gender fluid as being like David Bowie Pop star icon type of mindset ect.

Sorry I went off on tandem with my ubove post like that @zurala ,

I rember being very much Tom boyish and prefer tracksuits as a child too,
more fun...

I wonder if it's just a phase she is going through as a teenager @zurala ,

I think it's quite normal as a teenager to explore ,question your own identity , ect,
it's probably been that way for eons of years as tranisational confusing phase of growing up into adulthood ,

The difference today, nowadays is the cultral society and peer pressure, seems to be a lot different,

as its become ,or can be real problematic terriority if not handled or percieved in healthy balance , of questioning rigorously the extreme far reaching irreversible impacts of body altering modifications top.

I went interestingly a few years ago to one of interestingly talks on this transgenderism, a former male mental health hospital nurse, and a former member of a bikers gang, when he was in his early fifties, decide to take the ultimate decision to have sex change become female and all that entailed to becoming female,
said knew from age 5 yrs age, allways prefer idea of play acting/more comfortable being female,

I totally understand that someone can feel this way inclined,
but disagree strongly on a child or teenager going on process, at such a young age, of changing into a different gender ,sex change, as that age, you are still learning, developing emotionally,/mentally/psychical aswell.

Interestingly at same time of Transgenderism Talk , there was a news story of someone who had started on process of this, in as much taking hormone treatment aspect of this ,
this young person of 19 yrs age, Regrets now doing this and is blaming his Liberal minded parents for giving thumbs up go ahead ect
so it was a test case news story.

Part and parcel for ASD children at the minute.

The only way out of it if she's not influenced at school is to reduce online activity but it's everywhere now, even young children's cartoons.

I let DD do as she pleases at school but made my views perfectly clear and that I won't be using they/them pronouns.

For most children I worked with within secondary school the phase reared its head in year 8 and then reduced in year 11 or the move to college.

The attraction seems to be that children who feel like outcasts either through ASD, trauma find the trans/non binary community accepting so you have to try and emulate that through other areas. Sports teams, craft groups, volunteering with animals. Anything to give them a sense of belonging preferably a way from any form of media.

Does she understand the difference between gender and sex? If so, I'd just go with it, there's nothing wrong with experimenting with the social idea of gender (hair, clothes etc), like you say it's personality and everyone's personality is fluid.

If she doesn't understand the difference between sex and gender I'd have some gentle conversations along those lines to make sure she does.

Fine to be gender fluid. Sex isn't fluid and really dangerous to pretend that it is.
