The problem is that, in this situation, no decision IS a decision.

Up until puberty, boys and girls are quite similar. It’s puberty that causes the lifelong changes. We already know that delaying puberty doesn’t cause long-term issues. Puberty blockers are used to treat or help with other conditions. By blocking puberty, you are buying time. Time for the child to mature. Time for phycologists to assess. Time to practice the role before locking it in permanently. Time to grow, learn, and make the very decision you are talking about.
