A gender fluid child who at 10-years-old decided they did not identify as a girl or a boy says their identity can change throughout the day causing a lot of 'doubt' in their mind.

Annie, now 12, was browsing the internet after growing up as a girl feeling something was amiss and came across a website on non-binary children.

The Australian school student instantly realised they were gender fluid, but often questions the choice after waking up some mornings feeling more masculine or feminine.

'If you constantly say "you're a girl" and you put me into that box I will feel very, very hurt because I do identify as gender fluid, meaning some days I do feel very, very masculine, I feel like I'm a boy, there is nothing you can do about it,' Annie told ABC's Lateline on Wednesday night.

'There was some point where I was for almost months at a time feminine or masculine very specifically and that's where it gets confusing because you start doubting yourself, a lot, whether you actually are gender fluid.'

Annie's mother Marita told the program clothes shopping can often be a struggle as it is dependent on how the child feels each day.

'She's still just Annie, it just means that some days Annie is a girl, some days Annie is a boy and some days she's both,' Marita said.

When the pair went shopping for Annie's graduation outfit, they purchased both a dress and suit as they were unsure which gender the child would align with for the evening.

Annie believes gender is more of a mental trait rather than physical.

According to Lateline, a third of children who identify as non-binary find gender specific school uniforms inappropriate and 55 per cent are not comfortable with the toilet facilities.
