People act like natal puberty is the neutral choice here - it’s not. The first wrong puberty made me actively suicidal and that’s not unusual. If a kid has gotten so far as to get to a doctor about this, it’s pretty clear that something is up (cis people generally don’t question their gender in the first place) and by waiting on puberty blockers you’re allowing further suffering and irreversible harm to a trans kid. Puberty blockers are a very low risk way of hitting pause and if the kid decides to go through with natal puberty they can just stop taking puberty blockers with no harm other than a delayed puberty.
