Seeing their toddler playing with scissors can be a terrifying sight for any parent but for Kerry McFadyen it was a moment that changed everything. The 32-year-old came across the scene in the bathroom of her home in Strathspey, Scotland, when three-year-old son Daniel said he wanted to cut off his penis so he could be a girl. It led to his parents making the difficult decision to allow Daniel to become Danni, in what is believed to be the UK's youngest case of a child wanting to change sex.
