Guess who's crawling?

Emily is crawling around the house like mad. She can military crawl, and gets faster everyday. She loves to discover every nook and cranny of our house, and usually ends up stuck in a corner somewhere. She can get on her hands and knees and crawl a bit but likes the speed and stealth of the military crawl. She loves to get on her hands and knees and rock back and forth. She's sitting up by herself better and can almost sit from a crawling position. It's a beautiful sight to see her smiling red head poking up over the crib padding in the morning. Every day she seems to get faster and stronger. We need to put a brick on her head; she's growing too fast. Some pictures and a video taken last week of the speed demon herself.
