Livvy and her mum, Saffron and dad, Phillip have spoken about Livvy's situation, appearing on This Morning to discuss her experience.
With a passion for pink, Livvy dressed in a heart print jumper and sparkly jewellery for her interview, sitting with her mum and dad to bravely talk about coming to terms with gender dysphoria.
The 10-year-old said she was happy not to have to pretend anyone, and was glad that, at first, most people were accepting of her change.
Speaking to the Daily Mail, Livvy said she was excited to head back to school as girl, finally feeling comfortable:
'Walking to school on my first day back, I was nervous and excited, but most of all I just felt like shouting 'Yeay!'
'I was so excited that I didn't care what people thought about me. Even if people looked at me or were saying nasty things, I didn't care. I felt happy because I could be me and didn't have to pretend any more.'
What do you think? Too young to make decisions like this? Or congratulations to supportive parents?
