She can't crawl, but she can get where she wants to go

Diana is now officially 7 months old - and she wants to crawl SO badly!  She is really close to making it happen, too.  She can get up on all fours and rock back and forth - but when it comes to actually moving, she gets a little frustrated and has found a more efficient way to get from point A to point B:  an army crawl.  She drops her back end, and drags herself across the floor to the toy she wants!
