Forward Motion?

We've always been fond of the "Sherm the Worm/He liked to squirm" song, but you seem to take to a whole new level lately!  You're not really content to sit still for very long and are already getting into the crawling position. 

There isn't really any forward motion yet - you eventually end up laying on your belly.  You're very content there for quite a long time and still aren't rolling over to your back. (Just checked your brother's baby book, and it turns out he didn't master that until he was 8 months old - so apparently you're right on track!)
