I did have three boys. One of those boys has told me persistently, consistently and insistently that they are a girl.
Oh my goodness. I feel so, SO sorry for your child.

I truly mean this to be helpful. Please, please take note.
3 year old children CAN NOT be 'trans.' They just can't.
When I was younger, I remember wishing I was a boy, and even saying 'I want to be a boy!' to my mum. It was a big thing.
What my 5 year old self meant was 'I want to wear trousers to school and play football and cars.' By 15, I was a totally girly girl, albeit very sporty.
Now my point is - if my parents had said to me, age 5, 'OK, if you're sure, then you can be a boy. Are you sure?' I would have said. 'Yes!!!! Thank you!!! I'm so happy, let's go buy trousers yayyyyy!!!' ........and set myself up for a lifetime of psychological trauma.
It is FINE for your son to be feminine. It is FINE for your son to enjoy 'girly' activities. It is FINE for them to question things about their identities as they grow.
But it is absolutely NOT fine, for you as a parent to encourage a childhood fantasy which will have serious consequences for your child's mental health.
As a parent, I have no doubt that you want to do the best for your child. But encouraging them that they are 'wrong' somehow is not achieving this. It is failing your child.
And, although I am not for a moment suggesting that this has been done intentionally, or even consciously, have you considered that your desire for a girl could have been picked up on by your son? Children want to please their parents. In a simple 3 year old mind, he could easily have gone
'hmmm, mummy wants a girl. Mummy, I'm a girl now I'm a girl!!'
Mummy - 'are you sure you're a girl?'
Child - 'yes yes, sure I'm a girl.'
It is frightening.
Please, PLEASE think about what you are doing to your son by encouraging this. You will certainly damage him psychologically if you continue down this path.
I know parenting is hard. But please THINK BETTER of this
