Let The Crawling Begin!

So its that time in our house once again. Time to baby proof everything. (This was so much easier when I only had one child to worry about, and there wasn't any more of them to leave little "treats" all around for the baby to find). Jack started really moving around about 2 weeks ago. He would roll over and scoot in a circle. He could make it around the front room in no time flat. And now he's on his hands and knees. He hasn't mastered the actual forward motion of the crawl, but he doesn't go to his hands and toes and kind of "jump" forward with all of his might. I can't believe that he's old enough to be as mobile as he is.
