Yes - there's loads to do.
There are 68 kids shows at the 2003 festival.
Some of these are written and produced by kids and loads of them have children acting or featuring in them.
Every day there are free performances on the Royal Mile between 11am and 9pm.
You can watch loads of people like street performers, buskers and miming artists, and it's a bit like being at a carnival.
Kids can also take part in loads of the shows - singing, dancing and even sword fighting!
