In this video, Amelie shows that she can roll over easier and more often than she was last month. There are 8 and a half rolls in the 3 and a half minutes of the video, so about one roll every 25 seconds. At the end, she's reaching under the coffee table for the ring Sam threw there earlier.
*She has rolled to the left before, but it doesn't happen very often.
** And sorry about the lighting; it looks like the only light on was the lamp on our end table.
