he's only 5 months old?? The kid thinks he's supposed to be crawling already! What's next? A beard and a driver's license?! heehee!
Seriously, though, I really think he's going to be actually crawling within a couple of weeks. When we got home today, I put him down so I could change out of my work clothes and he promptly flipped over and got up on all fours and started rocking back and forth. In my experience, the next step is to start moving! Holy cow!
