A crawl like no other

I had to catch Corinne's crawl on video since it's too hard to describe. She's been doing this since she was 6 months old and hasn't progressed to getting on her knees. I don't think she ever will. She has already started pulling herself up to things. And if you look closely you'll notice that she uses the back of her right hand to help pull herself along instead of her palm. It makes her look even more retarded!
