At just 10 years old, Emily wears a size 12B bra, and carries around tampons in her back pack.
She’s not alone.
“The change in our diet and the change in our weight has had a massive impact on puberty,” she told This Glorious Mess hosts Holly Wainwright and Andrew Daddo.
Why are kids going through puberty as young as eight? Post continues…
“We have an obesity problem and we’re also taller – every generation is about three or four centimeters taller than the generation before it.
“Basically, we’re bigger people,” she said. “And we now know there’s link between the shape and size of our bodies and how early we go through puberty.”
By grade three most girls have started to develop breasts and by the time they reach grade six, at least 50 per cent of girls already have their period.
Dunn says we need to start the conversation about puberty earlier and talk to kids about how their body is going to change before it happens.
“There’s no point telling kids about puberty when they’ve already got their periods, are having wet dreams, or experiencing unwanted erections, and are completely baffled by it.
“We need to start having a conversation with kids about their bodies, about how their bodies are going to change, and take away some of that embarrassment at a younger age.”
Dunn believes schools should be responsible for teaching sexuality education at a younger age, but she says parents have a role to play too.
“Kids have more access to adult images and ideas than ever before,” she explained. “We need to provide counter-information to that because we don’t want kids picking up their sexual education from random sources online.”
