Yes. For the hundredth time (and literally just above your post) you can't just go to a doctor and say you want a sex change. Child or adult, it doesn't work like that.
After everything else, you still have to live full time as your identified sex before you can have gential surgery. Acting before puberty, this reduces the need for other surgeries like facial feminization surgery, and their bodies will look far more like their identified sex than their birth sex.
I don't remember where I disagreed with this-the first point. That works with anything, like the example I gave about depression. One can't just say "I'm depressed" and get treatment for it.
I just feel it's a bit more tricky before puberty because of what I mentioned about teens not knowing if they are transgender and their feelings of whether they are non-binary, both gender, non gender, so have you. How young before puberty should children be considered to have treatment?
Like my depression example, at a young age if someone has depression and anxiety symptoms and says their sex and gender doesn't match up, what other more distinct (or are there?) criteria a child must have in order for doctors to recommend any type of treatment at a young age?
After puberty there is no way to reverse the changes in skeletal structure once they happen. And after it's very rare for us to reasonably pass. If I didn't have a rectangle shape and amazing hair I probably wouldn't ever pass. And passing is being accepted, and being accepted is how gender dysphoria is diminished.
But I'm talking more of the child's health risk depending on how young the child is, if he has symptoms specific to dysphoria, and what doctors would have enough knowledge and experience to determine whether a child should have treatment beyond the child saying he or she is not how they were born.
In my opinion, for medical reasons, I'd wait until the child is old enough for the doctor to determine they have clear-cut symptoms of dysphoria and criteria for treatment. Outside of medical issues such as how someone transgender feels about passing and things of that nature, I couldn't comment. I can see an adult balancing health risks of transitioning and their personal views and emotional involvement, but not children.
