Festivals with kids: a survivors guide

When I think of music festivals I'm momentarily transported to my youth: a summer weekend filled with great music, great friends, copious amounts of alcohol and not a care in the world as we danced late into the night. Fast forward a few decades and a few kids later and the thought of going to my favourite music festival now invokes a whole new set of feelings, mostly: how the hell am I going to enjoy the vibe and still look after two rambunctious little people?
