The Little Man is Crawling!

E has been rocking back and forth on his hands and knees for weeks. He looked like he was so close, but never managed to get beyond moving just one knee forward. He was much better at "crawling" backwards than moving forwards! But all of a sudden, a couple days ago, he started to slowly move across the room to get one of his toys! I almost thought I was imagining, because he never stayed where I put him down. He would roll or turn and magically move to a different spot. But I have proof!
