I didn't fall in love with the book "Chicka Chicka Boom Boom" until I listened to the CD. Now I can't get the words or the songs out of my head. My daughter is obsessed with the CD, and I find myself singing the words while trying to go to sleep at night. Kind of a nightmare. Anyway, it's a cute book with a catchy tune so buy the book/cd combo. Great for little ones learning their ABCs.
