Children's Monkey Story

So I was playing with my son a few days ago, and talking about monkeys, and making up a story about them.  He said that would be a good book.  So we decided to make a children's book.  We came up with a good story (with my prompting for a couple different options for him to choose) and fun characters.  I've had him draw the monkeys and I've used my limited artistic drawing skills to make the backgrounds with his input.  This has been a lot of fun and should be a fun story to read to him and his brother at bedtime.  I'm not sure how long this one will take between my schedule and his attention span, but we'll see.
