The Army Crawl... and More Teeth

Jason started crawling last week!  He doesn't like to rock up onto his knees, but moreso lurch forward, then push himself across the ground army-crawl style.  It gets him where he wants to go, so I guess it works for now!  In addition, he has cut two more teeth on the bottom, making a total of 8 teeth just before he arrives at the 9-month mark.  They all seem to be coming in pairs and rather quickly in succession.  Since Jason does not handle teething well (ie cranky, drooly, and horrible sleep), I sort of hope he just get them all in as fast as possible, so we can be done with this for a while!
Here is a video of the family hanging out last night, featuring some awesome push-ups by Tony and a little bit of crawling by Jason:
