I do believe that you can be born in the wrong body (we know meiosis isn’t always perfect).
But from what I’ve heard from genuine people is that it’s 1) stereotypes that an issue and 2) that their bodies don’t match their brains.
How can a 3 year old be disgusted by their breasts when they don’t even have any.
Most 3 year olds wouldn’t even know or care that they have a vagina whilst the boy sat next to them has a penis.
And they definitely wouldn’t care that they want to play with a car whilst the boy next to them plays with a doll.
I have taught my child that gender stereotypes are nonsense and that she can wear, play or have a career in whatever she wants.
If when she is an adult she believes she is trans then I’ll be supportive but there is no way I would ever encourage her to transition at a young age.
One of her friends transitioned in primary school.
I’m sure the parents did what they thought was best but this poor kid has been bullied relentlessly and has had to move to at least 4 different schools.
As parents we need to encourage our children to be ok and confident with who they are.
Teaching a child at a young age that they can just completely change themselves when they’re not happy is setting them up to fail, especially when the teenage hormones hit and they all feel insecure.
