No?!?

This past week, Madeline has learned how to shake her head back and forth - as IF she's saying "no", but she doesn't say anything or even make a sound. We're not really sure she knows what it means or why she's doing it! She usually does it when we're feeding her. We offer her a bite of something, she shakes her head back and forth, and then eats it! We think it's really funny, as if she's saying, "No, no, no, no...okay!" We'll see how long it takes for her to REALLY understand what it means! I have a feeling it won't be long...ha!
