"What if I was to tell you that a game of peek-a-boo could change the world?," asks Molly Wright, a young student from Queensland, Australia. At just seven years old, Wright is a passionate advocate for early childhood development and one of the youngest people ever to give a TED Talk (link below).

Breaking down the research-backed ways parents and caregivers can support children's healthy brain development, Wright highlights the benefits of play on lifelong learning, behavior and well-being, sharing effective strategies to help all kids thrive by the age of five. She's joined onstage by one-year-old Ari and his dad, Amarjot, who help illustrate her big ideas about brain science. (A TED Talk supported by UNICEF and produced in collaboration with Minderoo Foundation as an educational tool for parents and caregivers around the world.)
