I was struck by you describing your child as "possibly the most beautiful little girl ever" because beauty is a highly prized characteristic in little girls, MenoMum4.
It seems likely gender dysphoric children are the product of a society that forces them into increasingly narrow gender boxes.
It's all stereotypes. Girls are 'sweet'. Boys are 'cheeky'. And it has serious consequences. For instance boys aren't encouraged to be docile. Girls are, and it's obvious that we'll see fewer leaders and bosses among girls taught that nice little girls are docile.
That's what I was explaining in my post about socialization. Boy and girl children are valued for very different qualities, or rather perceived qualities.
I say "perceived" because when the real sex of small children is disguised by a change of name and clothing they are treated completely differently.
I feel it's far better to encourage anyone with gender dysphoria to come to terms with the fact of their sex and the reality of their body.
There's no such thing as "being born in the wrong body". You only get one, and you are your body.
Telling them hormones and surgery will solve their problems is unkind because it isn't true. People can't change sex.
Plus the effects of testosterone on the female body are brutal. Far more brutal than the effects of oestrogen on males. Research it with your child.
After only a few years women are stuck with permanent male pattern baldness and body hair. Their vulva and vagina atrophy. They will need total hysterectomies because of the increased risk of certain cancers.
As I said, brutal. And what if you change your mind? I've seen blog posts and YouTube videos by detransitioners. They're heartbreaking. Perhaps watch some with your child.
We all thought we'd always feel the way we did then when we were 16. We were wrong.
