It's exceedingly rare on an international level that children medically transition at young ages. Many trans people never medically transition. The issue is the amount of misinformation people like yourself who fall victim to misinformation because you don't actually want to speak with trans people or their families. The church has no problem sexualizing children at young ages, parents calling their kids "Ladies man" or "heartbreaker" while parading them around and gushing about their little cishet crushes at young ages, people have no problem altering the sex organs of their young AMAB children through circumcision. There are many more examples, but I'll keep it brief for your benefit.
