I find it sad for the children involved.
Yes the way society sees gender is changing, but adults shouldn't be allowed to use their children as pawns.
My dd2 prefers 'boy things' and that's fine because she's an autonomous being, and there's no such thing as boys things, it's just stuff.
She is however, a girl. I am not an advocate of gender neutral, I am however an advocate of happy children. If that means my long red headed beauty wears a spiderman baseball cap and blue dinosaur dungarees so be it.
