transgender operation at 12 years old

The Sun has a story of a boy who has begun the change into a girl over the summer holidays.

A BOY aged 12 turned up at school as a GIRL - after changing sex during the summer holidays. Over the summer holidays his parents changed his name to a female one by deed poll. He is preparing to undergo hormone treatment and surgery - and could become the world's youngest sex-swap patient in the coming years.

I have absolutely no idea what that child must be going through but I cannot understand how a 12 year old can make that kind of decision. Juniorff1 has just started secondary school and I don't think that she is capable of making that kind of life altering choice - especially before puberty.
