Zade's Library find

I took Aria and Zade to the library last week.  As soon as we walked in, Zade saw a book with a bright green cover on one of the display cases.  It was titled, Blaming Islam. Zade immediately picked it up and began to carry it around the library with him.  About 45 minuted later, I checked out all of our 30 books and DVDs that we somehow managed to accumulate and began to leave the library, when the library door monitors began beeping.  I looked down and realized that Zade was still holding that Islam book.  I pried it from his hands and handed it back to the librarian because I had already reached my quota for checking out books, and besides I didn't think that  Zade really needed a book titled Blaming Islam.  He began screaming!  He wanted that book!  I hoped that I could calm him down, but I couldn't.  Finally, I just picked up my balling Zade, and my 30 books, while trying to usher my 4 year old, from the library to the car.  After holding Zade for about 15 minutes once we reached home, with him heaving on my chest, he finally calmed down.  Well, yesterday we went to the library again.  There was that Islam book on the display case!  Zade saw it and recognized it immediately.  He grabbed the book and began to carry it around the library.  This time I made sure that I checked it out for him.  He's been carrying it around every where he goes, ever since.
