We recently traveled to the UK with our then 2y7m old twins. Flights are tricky as we all know, as they require smart packing, a lot of thinking and the ability to be fast and effective. We didn’t pack much, just as much as we could carry actually. And since we also have to carry the boys, this isn’t much. We are far more comfortable with road trips, so we gave this a lot of thinking and we tried to be as light as possible.
