roll over! roll over!

Liam rolled over from his tummy to his back, for the first time at about 5 weeks old. But it was so sporadic that he did this, that I thought it was just kind of a fluke. But now...watch out! Don't be leaving this baby on any beds or couches! And make sure he's strapped in his swing or lamb chair! He's a movin'! Here's a clip of him rolling over!
