Four on the floor

R2 is now getting up on his hands and knees and rocking in "crawl position". We have been putting toys just out of his reach to try to get him going. Of course, when we say, "R2, come get this. You can do it," Boo either (1) gets it and gives it to him, or (2) gets it and says "Look, I did it! I did it!" Despite his sister's interference, we're pretty sure he'll be mobile soon. He really wants to GO and his scoot, turn & roll trick just isn't satisfying him as much anymore.
