OK. Well what do you call a child with a penis that from a very young age doesn't want to be a boy, that wants to be a princess, wear pink, plays only with girls, chooses his own female name, wants to wear dresses, plays exclusively with dolls, prams, plastic food and kitchens etc.
Any one of the many boys I have minded over the years.
They have all played with the dolls, put them to bed, fed them, changed them. pushed them out for walks in pink buggies (it was the only colour you could get) played with toy food, cooking stuff etc but it didnt make them girls.
The girls also played with train sets, cars, trucks, tractors, farm animals etc. It didnt make them boys.
Kids play with any toy that takes their fancy and stimulates their imagination. It doesnt mean you should ship them off to be enrolled on the trans programme before they have even stopped growing and developing their own identity.
Hell I was a tomboy, played with guns, played cowboys and indians with boy friends, climbed trees, yadda yadda yadda. By todays standards my parents would have been convinced I was born the wrong sex and I would now be a trans man'.
