Close to Crawling

I laught at myself when I think back to what I considered "close to crawling" looked like with Brennan.  As I watch Tyler do things that Brennan never did, I realize that Brennan never even really attempted to crawl.  Tyler has been trying to get around and often rolls and slides around on his belly, but in the last few days, he's been getting himself up on his hands and knees, pumping his body back and forth.  I think we are on the brink of putting the baby gates back up.
