He's a Babble Baby

Gavin has always been a noisy SOB, but he's recently become a babble baby too. In the last few days, he has begun to babble rather loudly for 10-20 minute stretches. It's ridiculously hilarious. Once he starts, he won't shut up until he's done. It doesn't matter if you talk back or if you're quiet. This episode below happened in the waiting room at the doctor's office.
