My mom is always telling me to fly with Olive and Charlie to LA because she doesn't think Mr. Bee can take care of Charlie by himself if I were to only bring Olive. (I know he'd be totally fine.... as long as I froze some food).
But I don't think I could handle flying with both of them by myself! All the stuff you need, and tending to two kids who both need a lot of your attention on a 6 hour flight.... which is actually 9-10 hours of travel....
Could you? Have you?
