Your kids are mirrors of you. When I'm in agreement with something, I say, "Oh, right." So does Sydney now, usually in perfect context.

Nathan and I only call each other "Honey." We even call Sydney "Honey, Sweetie, Pumpkin." No "Nathan" or "Lynn," usually not even when we're mad. Sydney will run through the house and sometimes calling after us, "Honey?? Honey??"
