Planning is always a good thing when traveling. While it's fun to be spontaneous, sometimes a little extra planning can make a trip go smoother. This is especially true if traveling with kids.
Make a list and check it twice. Kids need different things than adults. And, they need different things in airports, on planes, waiting in line, in restaurants, going through security...you get the idea.
If you are waiting in a connecting airport, check out that airport on line to see what restaurants or activities are available for kids. Older kids may enjoy the museum at the airport while younger ones may be entertained by the aquarium.
Travel as light as you can. This is where your list comes in handy. Try to pack a day or so before you leave. Forget something? No worries...there are stores where you are going. If you are staying with or visiting relatives, ask if they can pick up simple supplies you use. No sense packing a week's worth of diapers if you don't have to.
