He's also cruising back and forth a bit while holding on to low surfaces. He's too short to cruise along the couch like most babies do. That's what happens when you start being so mobile so crazy early.
I enjoyed it when he was happy crawling back and forth across the room. It was nice while it lasted. He's crawling faster and faster. How is he growing up so fast??
The "baby" tag I'm putting on this post seems less and less appropriate.
