Emi: the big talker

I'm a little behind (when am I ever caught up these days?), but here is a video of Emi at 4 months (she's 6 months now...) when she really took off with her 'talking'. Here's one of our "conversations", and though I know it's a bit long, you should at least keep watching to the 1:08 mark. :)

Why is it that they always spit up for the camera?
