When traveling with kids, you need to take a bit more time planning each trip detail. Plan your trips differently than you do when traveling without them.
It is a good idea to pull out your luggage at least a week before departure and do an initial pack of everything you think you will need.
If traveling long distances, it's important to pack enough snacks for children for those times when you are not able to purchase food.
If you are bringing any devices to use during your travels, be sure to download any movies before you leave and make sure to charge them fully.
These can help keep children busy during long flights or car rides which is always a bonus when traveling with kids.
