I completely forgot about this topic, but I figure I would reply (after a 4 month hiatus) with updates. Thank you all for your responses.
Marvel no longer bites (what a relief!). It stopped around the time that all of his adult teeth were falling out, so I assume it was related to the discomfort of his baby teeth. He will play bite every now and then, but nothing drastic.
Marvel no longer wakes up absurdly early now that he's 6 months old, as someone pointed out. He typically gets up when we do except for the rare occasion here and there.
Marvel has been marvelous and his behavior only gets better. The only "issue" we deal with now is his separation anxiety when we leave him in a crate. I'll probably make a separate topic on this. And he seems to be strangely attached/dominant to my girlfriends underwear when he manages to get a hold of it...
Thanks!
Peter
