These days girls tend to stop playing with dolls around 8 or 9. I can't imagine a bunch of high school girls choosing to play with Barbies unless they felt they had to 'be kind' to someone.
good point, only one of my DDs played with barbies and they were ditched long before the end of primary school.
I know a couple of boys who have girls as their entire friendship group - the boys are rather camp and they all have a lovely time together (although sleepovers will be a no-no).
It doesn't mean that the boys should really be girls - those two boys are the perfect illustration of a boy widening the bandwidth of what it means to be a boy (although how we regressed to such narrow sex stereotypes after the Olympic standard boundary pushing of the 1980s I don't know).
We still haven't established any idea of the frame of reference that doesn't involve stereotypes that a boy (or a three year old) would use to determine that he is really a girl.
I also think it is really sad that the child in this video is being encouraged into a situation where at a time when children are extremely conscious of their changing bodies anyway, adults are confirming that this child's body is wrong and needs to be changed fundamentally with powerful drugs.
It struck me when Joppe was in the pool and mentioned that they were constantly worried about their penis being visible and looking enviously at the girls bodies.
If Joppe wasn't trying to present as a girl and constantly worrying about not 'passing', I think a layer of stress would be removed from their life.
