Luke rolls over!

So everyone keeps telling me how "small" I am compared to Lexi. Grandma just says I'm gonna be a lean mean fighting machine. Well, I might be smaller than Lexi was, but I'm certainly moving quicker than she did. Lexi was over 6 months before she could finally roll all the way over, but I've been doing it for 2 weeks now, and I'm not even 4 months old yet!! So, THERE!!!
