Before he left was "Now Carson don't do anything new while I'm gone..."
So why is this new? Crawling isn't new to him, he's been moving (starting with the inch worm) since he was about 7 1/2 months and he's gotten up to a pretty good pace and can move freely around the house. But he still does it on his stomach. I can't remember the exact statistic but the majority of babies who crawl do not crawl in the typical fashion. They drag legs, slide on their bum, wiggle etc... and Carson's method of crawling makes him like he's going on a recon mission - he drags himself forward with his arms and uses his leg to shimmy himself. But yesterday he started crawling in the "normal" way. He doesn't do it all the time, only if the distance is short enough. If you put something about 2 feet away he'll crawl this way. Otherwise, he'll drop back onto his stomach. I think it may have something to do with the fact he feels more comfortable grabbing something if he's on his stomach. At the end of the video you can see him drop onto his tummy right as he reaches out to grab the ball. It's cute as hell though, I must admit.
