Anyone's elses baby does this? the first time I hear it I had no idea what it was, until I saw the smile on her face. Now it happens all the time, and the other day she finally did a giggle while awake.
The cutest time was when I was talking "maths" (im taking college algebra) to my DH and she couldn't stop smiling and giggling. "horizontal asymptotes" was her favorite word that night!
