Luke rolls over for the first time!!

Luke rolled all the way over from his back to his stomach this morning!! I totally missed it since I was zoned into the computer! All the sudden he was fussing a little so I looked up and he was on his stomach!

He's been so close to rolling over for quite a while now but just couldn't get his bottom arm/shoulder off the ground. Of course now I have him in my sight while I type this but he's not even working on trying to roll! Hopefully I'll catch it the next time.
