All children go through a stage of who am I? Confusion etc.
Am I a boy, a girl, do I fit it etc.
The social contagion of affirmation of 'I'm in the wrong body, so need to change it' it IMO so damaging.
Talking through, understanding that all children go through 'who am I'
rather than initial blind affirmation and ok.lrts change your name, clothing etc tell school rush into changes young BEFORE maturation, is so dangerous.
