I think I mentioned that Sarah Graves has started to sign more. We took this video when she first started doing it (and I was a little hesitant whether that was actually her intent) and she has really started using it all the time. If she takes a break while nursing, I can ask her if she wants more milk and she signs more and goes back to the task at hand. She has also become really good at telling you when she wants more food. Especially, if it's something really good!
