Given his fussiness the past couple days, the sucking in of his lower lip, and the general "I'm going to eat everything put near my face or at least chew it into submission" thing, we're pretty sure Pike is working on cutting his first tooth. I personally can't tell the difference when massaging his gums, but, let's face it, I have no idea what I'm feeling for.
So god have mercy on our souls. I hope it comes in fast... I think. Or not. Maybe it's time to wean. Eep!
