Her argument is that every child can thrive by the age of five, provided the grown-ups in their life do a few things right.
Molly Wright, from Queensland in Australia, managed to pluck up the courage to stand in front of an audience of hundreds to give her speech, which has also been viewed hundreds of thousands of times since.
She even brought out one-year-old Ari and his dad Amarjot to help illustrate her points.
Molly asked: "What if I was to tell you that a game of peek-a-boo could change the world?"
Well, we'll see about that, won't we?
She continued: "My talk today is about some powerful things you grown-ups can do to shape us as children and the adults we become,
"How do I know? Because my parents and people around me did them, early and often.
"I know not all kids are as lucky - some of my friends, some kids at my school, many around the world - and I would really like to help change that."
Molly went on to explain that childrens' brains grow rapidly in early life, and reach 90 percent of an adult brain by age seven.
That means those early years are crucial.
Teaching kids about important life skills and doing five things - connecting, talking, playing, keeping healthy, and enjoying a sense of community - can give the kids a great start.
She argued that kids who miss out on these things could go on to struggle later down the line.
Even before giving her groundbreaking talk, Molly has attracted comparisons to fellow child activist Greta Thunberg, who was 15 years old when she started her school strike for action on climate change.
Molly told News Limited that it would be a 'dream come true to do that [similar to Thunberg] for education.'
"I feel like I would help so many people", she added.
After watching her speech, Molly's mum was obviously proud of her daughter's achievements.
Writing on Facebook, she said: "Molly, I have no words, you are one very special little lady who might actually just change the world one day."
Molly was put forward for the talk by 'Thrive for Five', which is an organisation that is headed up by former Premier of South Australia Jay Weatherill, who wants to see better early education options for kids.
