I'm not exactly sure what the definition of wisdom teeth is (and no, I'm not going to wiki to look it up, that would be both cheating and a buzzkill).
Gabe's first tooth is now protruding far enough out of his gum to give you a nasty nip when he bites down. it's not particularly visible, but damn can you feel it.
Given teeth and wisdom go hand in hand (or at least, one hopes they do), here are a couple of links to wisdom for Gabe to read when he's older.
May he be as wise in life as I was stupid, and may he never fall flat on his face because he wanted to hold onto a cigarette and a pint of beer more than he wanted to protect his good looks.
