Mr. Lawyer asked me, "Why does the baby keep yelling "No!" at me and whacking me in the face?" (He's not kidding - for the record, she wields a mean uppercut.)
Me: "She's showing you your nose, honey. Isn't that sweet - she has a new word? Just acknowledge it, tell her she's smart, and she'll move on to poking you in the eye instead."
Mr. Lawyer: "Why can't you just teach her about belly buttons?"
