Smories is a website that features kids reading the stories they have written out loud. You simply click on each child's picture to view their story telling video. The stories can even be watched from your iPhone or iPod Touch if you have one
There are plans are to to publish 50 more Smories every month. Authors of any age and skill can write and submit a story, just as long as it's original.
Maybe watchng a few will inspire your children to have a go at writing one themselves? I know I will be incorporating this idea into some of my own writing lessons with my kiddos!
