I was able to get up on all fours last night and now I'm really making progress. I've been doing push-ups today (truly, just my hands and toes touch the ground). After the push-ups, I started squirming and crawling backwards about 6 feet. From there, I got up on all fours and managed to crawl a couple of feet before I got tired. Mommy is in for it. She keeps telling me to slow down, but I think I'm going to start climbing stairs and walking next week.
Pictures and/or video will be coming once my skills improve enough to catch it on camera.
