Attention aspiring children’s book writers:
If you are an unpublished author (please check the website for the rules about being published), then you should consider the 4th Annual Cheerios Spoonfuls of Stories New Author Contest. Basically, you need to enter by July 15, 2010 and if you win, your work will be published and distributed in cereal boxes. There are profiles of past winners at the Simon and Schuster site.
After finding a free copy of Duck for President by Diane Cronin in our Cheerios one day, we have been hooked on the Spoonfuls of Stories idea.
Edit: Although some of these links still work, check my 2011 post for the newest contest.

Good luck!
