Newsround Blog has previously advised parents of gender nonconforming kids to avoid having anything to do with a trans activist group called Mermaids.

Yesterday trans activist, Carol Steele, inadvertently proved my point in a post to an LGBT internet forum:

No reputable clinic either in the US or Thailand (or anywhere else that I am aware of) supports surgical intervention under the age of 18.

Would Mermaids recommend any disreputable clinics/hospitals - absolutely NOT.

In fact, the person in charge of Mermaids sent her own child to Thailand in order to get round laws that protect children in the United Kingdom.

"I never felt like a girl - I always thought there was something different about me" - that's what Leo says in one of the clips in a trailer for CBBC's autumn schedule. It actually comes from an award-winning, but highly controversial documentary called "I am Leo", which was first broadcast almost two years ago.

Perhaps people won't be surprised that Leo felt different when they learn that Leo's mum, Hayley, "knew" the gender of her child because of her difficult pregnancy.

Hayley Waddell: 'I knew when I was pregnant with Leo that something was different ... I've been pregnant with three other girls and this one was completely new. I was so horribly sick all the way through. I was just certain I was having a boy.'
