This baby is CRAZY!

I got a crazy video of Liam trying to...do SOMETHING. lol. I don't know if he's getting frustrated, trying to move along, trying to flip over, or WHAT, but the crazy baby managed to move forward about 2 feet over the course of the video. Before I started taping, he had rolled onto his back about three times, and was almost rolling from his belly to his back. He has some unnaturally strong legs, and they NEVER stop moving. His pediatrician commented on how active he was. Not a big shock to me, since I started feeling him move around 12 weeks, and I don't think he ever stopped moving...
