This finding is so bizarre that I wonder what kind of tests could possibly confirm the diagnosis. After all, if the child shows a preference for toys which are usually associated with girls, or girly clothes, what are we to make of the many tiny tomboys who prefer 'boys' toys', prefer trousers, and who grow up to be normal women?
We wouldn't allow a child of five's evidence in a court to be accepted without corroboration, if at all possible, because he is 'without understanding ' He may invent, imagine, fantasize, or simply go along with whatever he senses the required response to questions is.This appears to ignore that obvious principle.
