Crawla in Da' House!

Lucy, barely six months in this picture has started to crawl! I don't know whether to celebrate or cry. We're at a stage now where I'll leave her for a few minutes and come back to find her behind the couch with some strange item in her mouth. It's fantastic. She doesn't crawl on her hands and knees yet, it's more like a military crawl, nonetheless, she is mobile! Yikes!
