DNiece is off to her first parent-free festival in August. Her 16th birthday is a few weeks beforehand so I thought I'd make up a pack of useful bits & bobs, but I've never done festivals myself so I could use some help!
So far I'm thinking...
Mini dry shampoo spray
Antibac hand gel
Deodorant wipes
Sunscreen wipes
Waterproof mobile phone pouch
One of those mobile phone charger blocks that you charge at home & take with you to top up if you're away from electricity
Emergency tenner 
Picture frame to stick a photo of her & her mates in when she gets back
Anything I've missed, or anything naff that I shouldn't include?
All tips much appreciated!
