What is Christmas?

Elijah's favorite book of the season is, appropriately, a Christmas one, called What Is Christmas? He received it from Grandma Shannon last Christmas, but hasn't really gotten into it until now. He wants it read to him over and over and over and over (and over). I've been known to ready the book more than 10 times straight in one sitting (and then suppress an urge to destroy the book :)). We are not sure what attracts him so much, but our bet is that it's a picture of a puppy on every other page.
