As a child, I destroyed anything pink or purple, refused to wear girls clothes and often referred to myself as a boy.
I am so glad that no one intervened medically (hormones/surgery) in ways that I would be dealing with for the rest of my life.
I've learned that society's gender roles are wrong and that I don't have to conform to them or make changes to my healthy body, regardless of my preferences & choices.
Claiming 'transgender' reinforces gender stereotypes more than it refutes them.
In children, I think this is especially dangerous and confusing.
I do not mean any disrespect. Question everything. Eschew all labels. Look outside yourself.
