Standing and Rolling

This was Lizzy's birthday, and here is Emma, just past 3 months and ready to stand on her own two feet. With a little help from Daddy.
Today I put Emma on her back with her baby doll and went about doing my thing. When I turned back to her a while later, she had rotated 90 degrees and rolled to her tummy. She has done it three times today.
Watch out, we're going mobile.
