Laughs and growls

Boo loves to read. (well what she thinks is reading) She will sit in the corner and leaf through books. For the past several weeks she has been holding a book and laughing then giving a growl. I finally decided to look and see what book she does this with. This is it. She will often sit through at least 2 pages as I read it with her in my lap.
It is a good book. I guess she growls at the monster...I get such a kick out of watching her love for books start.
