I couldn't disagree more. One does not see a psychologist or therapist because one is nuts nor to get "fixed." It's platform for getting difficult to discuss things out in the open. A child of 7 knows quite well what is gender normal. Even if one's parents are open and supportive, that does not mean a kid will be willing to talk. Just articulating what they are feeling is a challenge and THAT is where a therapist of some kind can help.
I'll give an example, when my youngest daughter was about 10, she began to struggle with relationships with girls her age. She couldn't/wouldn't talk to my wife or I and just struggled. We FORCED her to go to child psychologist and she promptly refused to talk for the first three sessions (the psychologist will not tell parents any of the content of the sessions unless the child is at risk of hurting themselves or others and parents have to accept this). By the fourth session, my daughter was talking. After about 10 visits, she and the psychologist both agreed no further sessions were needed. A few months later, my daughter asked to see the psychologist again. The met a few more times and then stopped completely. The point is, an objective third party can and do elicit what is difficult for the child to discuss.
