Scrunchy Nose

Marlo learned how to make a new face today.  You can catch it at about 0:17 of this video.
On this particular occasion it appears that she is using it to show distaste for her food but I don't really think it's an icky face.  She was doing it off and on all day and it doesn't seem to be related to anything, just a new skill she's practicing.  It is usually followed by a little smile and laugh.
