Hitting puberty can be upsetting and confusing enough for girls entering high school, but it was a completely different experience for Emily McAuliffe, who had her first period when she was just four years old.
Emily, now aged five and a half, has been diagnosed with Central Precocious Puberty, which means this little girl is developing before her time.
For her parents, Tam and Matt, it’s heartbreaking. Their daughter hasn’t reached primary school yet, but is already the size of an eight-year-old and has developed breasts.
"What’s heartbreaking is she’s a five-year-old girl, and she just wants to do what other five-year-olds do, but she can't," Matt said while appearing on The Project on Wednesday night.
"It's hard when you can see that things are tough for her... you just try to make the best of a bad situation."
"She has missed out on massive parts of her childhood because we can't throw her around, she's 45kg, she's four foot six," Tam added.
Mum Tam Dover said their daughter has been bullied while at daycare, which makes her fearful of what Emily might face at primary school next year.
"It breaks my heart when she comes up to me and says 'Daddy, am I ugly?'," Matt says.
