Sammy makes these noises in the night that Aaron describes as the sounds of a feral animal digging in the underbrush. They are tapering off the older she gets, which is good because they are loud when in a bed right next to you, but sad because they are pretty funny.
A couple of weeks ago she started getting extra wiggly. One night I had heard her wiggling around in her co-sleeper and when she woke me up to eat I was surprised to find she had turned a full 180. She continues to be wiggly and it has been funny to see her in all sorts of strange sleeping positions.
