Just heard about this thing for under 18m olds called "Oogly Boogly". Basically, you put 8 children into this big, inflatable space with no toys and strict instuctions to let them so what they want (within reason I'm sure!). There are dancers/actors that move amongst them and mirror the actions & movements of the children and after a while, the children realise this and a kind of improvised dance, fun-fest ensues where the children get worked up into a joyus frenzy. Parents/carers just sit around the outside and watch. It sound fantasitc. \www.ooglyboogly.org.uk/main.htm{url\Here's the website}. Has anyone been?
