Advanced thumb sucking

We knew it was bound to happen with all of the fist sucking that Addy has been doing lately.  She has finally achieved honest-to-goodness thumb sucking!  It still involves the occasional scratch to the face (and it's often more thumb chewing than thumb sucking), but it's quite cute nonetheless.  The down side is that she usually swallows a lot of air when she's gnawing on her hands, so we have to try to burp her every so often, even when she isn't eating.
