At modern festivals, camping areas are often divided up between families and 'night owls' - people who'd rather party without disturbing children and babies who've been brought along. There are even festivals who turn away under 16s completely because they'd rather not have children exposed to the sorts of thing that go on at such gatherings. That wasn't the case at Woodstock.
As well as two children being born, little ones came along with their families to share in the experience, and nobody thought it was odd. Adults and children danced together and sat around the same campfires, all joined together by the same sense of community spirit and shared experience. For a whole generation, it was a weekend that formed their whole identity. These were truly the children of the revolution. Everybody at the festival believed that Flower Power was a movement that had started and could never be stopped.
