Finding her hands

Today we noticed that Madeline seems to be discovering her hands. We've read about an almost sudden change where babies will begin to study their hands with great interest. Today we saw her, on two occassions, quietly staring at her clenched fist, which she held about five inches from her face. She would contemplate it for several seconds and then move her fist to her mouth (she's been sucking her thumb more deliberately over the last week or so, too).

Obviously these pictures don't depict what I've described above - I didn't have my camera handy when she was inspecting her hand. I did take these pictures today and wanted to post them, even if they're not germane!
