My DD hated growing up. She’s the youngest with two older brothers and I think being the cute little girly one suited her to a certain extent (wrapping her softy dad around her little finger!), but she did play with her brothers’ toys, wear their hand me down clothes and play their games, so she didn’t look like a ‘typical’ girl might who hasn’t grown up with brothers.
She grew really tall in Year 6 (for her age, head and shoulders above most of her friends and some teachers!) and developed in all the ways girls do long before anyone else. She asked to have her hair cut short (or course, I did it for her - i also had short hair at that age and saw no reason why not).
I can imagine if she’d had a non GC mum her wails about wishing she was a boy, hating her breasts and being happy if she could never have a period again might have come with a dollop of “I was born in the wrong body”.
As it was, at every step, she has been under no illusion that she’s a girl, female, could not change that even if she were able to stop periods, lop off boobs etc
She went through a period of thinking she was gay, having crushes on female friends and celebrities. Again, all totally par for the course growing up and no big deal made about “coming out” etc, just an implicit acceptance that whoever she is and whoever she fancies/loves is perfectly natural and as it is meant to be. No song and dance, rainbow flags or resistance to any of it.
She’s now a very girly looking adult, with long blonde hair, cute little outfits that show off her amazing figure and a crush on a man she works with. At some point she may date a woman, she may cut her hair again, she may put on/lose weight, have surgery (hopefully not) to increase or decrease her boob size or have those godawful fillers or fat removal etc. to make herself look younger/older/more like a fox,
Whatever she looks like, she will always be my daughter, a woman, a female, she has always “lived as a girl/woman” by having short hair and wearing camouflage combat trousers and playing Call of Duty and hating her body for the attention it gets and the ‘gross’ and messy ways it behaves sometimes! She may never want to have DCs but she will always have the option to try because she was allowed to grow up naturally, despite many pointers that could have led another parent down a different path for her.
