 Some professionals, including Dr. Edgardo J. Menvielle of the Children's National Medical Center, who has specialized in this area in his clinical practice, believe that the proper response to gender-variant behavior is supportive therapy aimed at helping the child deal with any social issues which may arise due to homophobia / transphobia.These professionals believe that attempts to alter these behaviors, and/or whatever mechanism is responsible for their expression, are generally ineffective and do more harm than good.While not universally advocating for what childhood transgender advocates refer to as full social transition, the CNMC model generally supports allowing a child to express cross-gendered interests at home in an age-appropriate fashion.
