It is new to have a range for children.
I started this thread and I am certainly not laughing.
I have no idea if people know they are gay at 4 or 5.
If a child does say that, at that age, there is no need for affirmation or talk of future medical treatment. As they get older, they will develop into a gay teen & adult or they won't. No problems either way.
A child of 4 or 5 saying they are trans may have parents and teachers 'affirming' them with different name, different clothes, different hairstyle, different pronouns - all telling the child that this is a definite fact.
The child may go through the whole of primary school in that way, before they get anywhere near a medical professional.
If it was only a question of different name and appearance then no problem.
A question of not conforming to gender stereotypes for their biological sex - no problem.
A question of lifelong medication with unknown side effects, of surgery to create the illusion of being the opposite sex (in males, genital surgery that needs daily maintenance), of constantly being aware of living an illusion - then there is a problem.
No-one should want to hurry young children onto that path yet it is happening.
Even medical experts, so trusted by PaddyAnn, are afraid to do anything other than affirm children & young people and move them along the system.
