When our son Amaya, now 17, was in the second grade, his teacher brought something very interesting to our attention. Amaya was considered a tomboy by many of the other students and was often mistaken for a boy because of the way "she" dressed and behaved. (To be clear, I will always use male pronouns for Amaya going forward, even though our family and community used female pronouns for Amaya until he asked us to switch at age 14.)"
