Sign, sign, everywhere a sign

We've been doing some baby sign language with Sierra for about 3 months or so now. We just do a few signs, the sign for more, and for a few of the foods she likes, wash, sleep, milk, water.

Today she signed back! How awesome is that?! It was the coolest thing ever. We were eating breakfast. Sierra was sitting on Jason's lap and Jason was feeding her some pieces of sausage. Then, clear as day, she signed "more." Apparently, she digs keilbasa. Mmmm ...
