Grace Crawling??

Yes, I just posted about Grace sitting up. NEXT! Yet another milestone she's hitting, which is the BEGINNING of the crawling... uh oh. Yesterday she got up on her knees and hands, but went right back to her belly. Today she got up on her knees and hands then started rocking back and forth. She's been doing this all day today! After her morning nap when I went in to see her, she flipped over then got on her knees and rocked a little. Here is a short clip from a video I took of her. She would go from her belly to the knees and back and forth.
