Trying to Crawl!

Alexander is trying to figure out how to become mobile. He has been "swimming" on his tummy waving his arms and legs around. But in the last few days, he has been getting up not only on his hands and knees, but on his hands and toes - like he is doing push ups. He hasn't coordinated any type of movements yet, but he sort of scoots backwards and can turn around and roll around with the best of them. I have a feeling once he starts to crawl, there will be no stopping him!
