I am curious to know if they permit temporary puberty blockers to children who have developmental or mental challenges.

For example, if a young girl has a mental age of 3 and a physical body of 12, puberty and menstruation might be very confusing and distressing. Thus, puberty blockers can prevent her distress.

Because, if THAT is legal, then wouldn't it be discrimination to refuse the same treatment to a trans child who is distressed by what is happening to their physical body?

God, this is asinine. Bad enough that so few trans kids have family support to begin with. To target the few that do is horrific.
