North West boarded her very first international flight yesterday. How exciting! The little one is heading to the “spiritual home” of her loving parents, Paris, most likely to take in a few shows and teethe on a baguette or two. But wait: Is that a lady from the airline (Lufthansa? Air France?) carrying the famed Birkin diaper bag? If you’re analyzing the scene, wondering whether this heroic woman is leading the family to extra security checkpoints because it is highly suspect that someone would use a Birkin as a high-end carrier of baby poop receptacles? Well, you’d be wrong.
