Abigail has finally decided she'll learn to sit. Early on, when I'd try to practice sitting she would arch her back in order to stand. The bed probably isn't the best surface to learn to sit, but it is the most cushioned for the falls.
Please excuse the static noise on the video, it's due to all the fans in our bedroom. Abigail is only in a diaper because it hadn't fully cooled yet. (Should be fixed today, I wont be holding my breath.)
