What are the most significant benefits of wearing a bike helmet when cycling with children, and how can we effectively communicate the importance of helmet use to kids in a way that resonates with them?

Furthermore, how can parents and caregivers balance the need to promote independence and freedom on the bike with the need to ensure their childs safety, and what role does helmet use play in this balance?
