Rebecca reached a milestone yesterday, she recognized her reflection as herself. She looked in the mirror, saw that her reflection was wearing a pink barrette, and reached up and ripped it out of her hair. That seems to duplicate the classic experiment of putting red on a baby's nose, and seeing if it reaches for the nose in the reflection or its nose. Today she was looking in the mirror and dancing. Very cute, but less conclusive since she will happily mimic activities like dancing.
