@Mrs Erocse. This is actually not as uncommon as many people think.
I came out to my parents at age about 4, as long back as the 1960's, and because I was lucky enough to have incredibly progressive and well informed parents I was allowed to grow up somewhat between genders and fully expressing my female identity. They even found schools that could cope with my self expression as an, in my own words "almost-girl" to the extent that I was allowed to take class and sport options usually reserved for girls and indeed to wear a kilt (which to me was a skirt!) to school.
Back then everyone thought it was just a phase and that I would grow out of it, and indeed when I started therapy at 16 that is precisely what the therapist tried (unsuccessfully) to make me do. All he managed was a few years delay... years during which I became increasingly unhappy until aged 24 I finally obtained SRS. These days I am glad that they start therapy earlier, but I find it disturbing (from other reports that I have read) that some therapists at the portman still seem to concentrate on trying to "straighten out" the youngsters and this, from my own experience, can be profoundly destructive and unhelpful.
In short, good that they are starting to take it seriously, but I wish that there were less doctors who thought that earlier intervention would allow them to "cure" us. You do not need to cure someone from simply being themselves, nor indeed should you try!
