Laura Edwards-Leeper, a psychologist who helped found America’s first transgender clinic for children in Boston in 2007, has claimed (including to this newspaper) that too few teens undergo crucial mental-health assessments before starting treatment.

That they are discussing the risks at all nonetheless constitutes progress.
