Query: This is an eye popping little book!

This book was written by a 4 year old boy and illustrated by his father. It is a fun little book and a cool idea. Kids say the darnedest things -- here are 10 of them. Next time your kid starts talking, you better have your pen ready. It just might be the next big children's book.
