What do you think I am? A five year old?!?!?!

Attempting to write a children's book is quite possibly the most daunting task I have ever set off to do. I finished my first draft the other day (Charlie the Crawdad's Library Adventure), and reflecting back, I have no idea how the hell I am going to pull this off. The manuscript is 5 pages long, single spaced, and in Calibri 11 font! That's closer to an adult short story, than a children's picture book! Not to mention "the big words". I didn't realize how difficult it is to transform an educated adult vocabulary into "kid speak". Whoa. It's mind bloggleing to try and change the way you have written for an entire academic career, into something comprehensible to a five year old. I want to educate my audience, yet I want them to understand me as well. Can anyone provide me with a five letter or less word for aneurysm? Back to the drawing board.....
