9 year old changes gender

I found online an article from the Sun newspaper in England that a 9 year old child has transitioned from boy to girl. I dont know how reliable a sourse they are, as they also have an article saying they found a picture of the loc ness monster on google earth. But, if its true, i feel kinda conflicted. I am happy for this girl, but part of me worries that this is too early. I would have taken a transition at 9, and it might have been a mistake. I just hope she doesnt end up regretting her decision.
