We’ve gotten quite comfortable traveling by car with our three kids 7 and under. We always make it a point to be in a family friendly area that offers late access to drug stores if someone gets sick, a variety of meal options for our pickiest eaters, and stores where we can pick up our last minute essentials. We have it down to a science at this point, but when it comes to traveling by plane a lot more thought has to be put into it. Do we need a double or single stroller? How many carry on bags can each child take? Do we need to rent a car? What about car seats?
