Don't cut your teeth yet, Jack. The last week or so has found our little guy gnawing on fingers and chomping on a pacifier if its put in his mouth. If he can get his fists anywhere near his mouth, he practically growls trying to get them far enough in to chew on them. He has also been drooling like a madman.
I know that even if these signs do herald the beginning of teething, he may not actually cut teeth for a few months. But, he is not even 10 weeks old! Oh well, hopefully he follows his sister's lead and doesn't become a biter.
