An eight-year-old Australian girl has brought Kellogg's to its knees, forcing the cereal giant to promise it will put girls on its boxes of Nutri-Grain starting from next year.
The young Canberra girl, Daliah Lee, was ecstatic when told the good news on Friday, after complaining to Kellogg's that it put only boys on its Nutri-Grain boxes when girls could "also do awesome things".
"I jumped up and down and screamed, I was so excited," she said.
"Finally all my hard work has paid off. Children are important as well and need to be listened to."
Kellogg's issued a statement on Friday saying that, while women had featured on Nutri-Grain boxes in the past, there was now a discrepancy which would be addressed - thanks to Daliah's agitating.
"Hearing Daliah's passion and, as a company that values diversity and inclusion, we've decided that we will update the back-of-pack imagery with images of both females and males. This will be rolled out in 2019, so that we can continue to inspire all Aussies no matter their gender," the statement from Kellogg's read.
Daliah, a year 2 student at Southern Cross Early Childhood School in Belconnen, came across the discrepancy one morning over her usual bowl of cereal. Only boys were being shown on the box, all taking part in high-energy pursuits, such as mountain biking and surfing. But no girls.
"Why?", she wanted to know.
"I thought, 'Why aren't there girls on there?' Girls can do amazing stuff too. We don’t have to think one is better than the other. We're all humans."
Kellogg's was initially non-committal, sending back a letter that said it was sorry Daliah "did not like this product" and her feedback would be "forwarded to our product development team".
Her take on the response? "It was kind of blah, blah, blah".
When faced with the bland reaction from Kellogg's, Daliah started a petition on change.org to persuade the company to change its policy.
And, after being contacted this week by Fairfax Media, Kellogg's relented.
Daliah said she would only lift her ban on eating Nutri-Grain, which "used" to be one of her favourite cereals, when she saw the updated boxes.
"Only when I see the evidence they haven't lied to me," she said.
Mother Annabelle and father Adam were keen to encourage their daughter to see that she could make a difference.
"I think one of most amazing things is that she is at that beautiful age where she genuinely believes she can change the world," Annabelle said.
"It may be something as superficial as a cereal box but she's aware when something doesn't feel fair."
Daliah was also strongly supported by her school and its principal Lyndall Read.
Ms Read said she was "really disappointed" with Kellogg's initial response to Daliah, which read like a "form letter".
"One of the things we believe in is that it's really important to listen to children," the principal said.
"I think kids are very wise and we can learn a lot from them.
"Different people have said to me 'It's only about sugary cereal, so why should we worry?' But this is not about the cereal, it's about the images. And giving kids a voice."
Daliah, meanwhile, who likes reading Good Night Stories for Rebel Girls, and listening to the ABC podcast Fierce Girls, is not stopping there.
"I'd like to be prime minister," she said.
