Almost Crawling

Two weeks ago Amanda turned 6 months. She is almost crawling. She gets up on her hands and knees and rocks. She can crawl backwards but when she goes forward she doesn't know to move her arms--so she ends up head butting the floor. Despite the occasional bumps to her head, she is getting around pretty well and I have to keep a close eye on her to make sure she doesn't get wedged under the couch or chairs or that she doesn't crawl off the carpet and onto the wood floors.
