The other day, I had Addy propped up on the couch like this while her bottle was getting warm. When I checked it, it was still cold. So, when I returned, I dramatically told Addy that her bottle was not ready in order to keep her from crying. Instead, she started laughing. Since then, she has continued to do this and this little routine has kind of become our ritual while her bottle is warming up. So, needless to say my antics are a little embarassing, but sharing this is well worth the embarassment.
Here is another video of Addy talking.
