The favorite book

Lily's favorite book lately has been this baby sign book. It has different objects such as fish, flowers, doggy, kitten, etc. I forgot her favorite, which I actually don't even have a picture of. It is hat, and the sign for that is tapping your head. Except rather than tapping Lily really whallops herself on the head.
The sign for throwing a ball.
You obviously can't hear it but Lily is panting like a dog in this picture, it was hilarious.
The sign for talking on the telephone.
