She rolled over!!

She was being fussy in her crib and whenever she does that, she rocks back and forth on her sides. I went in to get her and she was completely on her left side almost rolled over but the side of the crib was blocking her. So I moved her over and waited to see if she would roll over completely and she did! I don't think she really knew what she did because once I got her up and changed, she wouldn't do it again. She just layed there and looked at me like, "What?"
