Me:

For those of you hungering for more familial anecdotes, here's a treasure. My two-year-old daughter, my wife, my newborn son, and I were all sitting on the couch, with my son as the wriggly, wrinkly focus of our attention. I unwrapped him from the receiving blanket so that my daughter could see his toes, and she noticed his belly-button with the drying umbilicus still attached.
Two-year-old: (pointing) Bellybutton!

Me: Yup. That's his bellybutton.

Two-year-old: (with look of amazement) Dere's a raisin in it!

In unrelated news, I've sworn off raisins, dates, and beef jerky for the next week or so.
