ATransMum I'm not sure you've read me correctly. I'm not saying GNC, gender dysphoric people or transgender people exist. I'm simply saying it's not possible to change sex however much surgery you have. Anyone can, and should, present how they want and be accepted for it.
No I'm not trans, but like others for a long time growing up I hated being a female and longed to be be male. I wanted my breasts removed and was horrified by my periods - honestly, it can be distressing losing what seems a large amount of blood out of your vagina. I do have a daughter who nearly 5 years ago suddenly announced she was transgender - I'm not going to go into our back story again - it's on here under my current name.
Your AFAB child says 'I want to be a boy'. Consistently, persistenly, over several years, and is self harming and has attempted suicide because they are going through puberty and does't want their breasts to grow any more.
You can:
a) Tell them they can't change sex.
b) Listen to them and talk to agencies like Tavistock about the right options
Which one do you think gives the child the best medical chance and quality of life?
Now, I've actually been in this situation, and we did both. As others have said, it's biologically impossible to change sex. We kept our debates calm and logical - never demanded she agree with us, but would question why she felt as she did.
That kind of advice is unhelpful, not medically relevant and could well pollute the minds of a parent. It's like prescribing homeopathy for cancer patients - it doesn't work.
She's now desisting and very not dead, despite having a mum with a polluted mind!
