Traveling with my toddlers has been one of the biggest sources of joy (and frustration) in my life. As much as I love traveling on my own, there's something special about experiencing destinations, attractions, food and more through their eyes.

To encourage more families to travel with their children, we created this guide on how to fly with toddlers. The goal is to make travel easier so you'll go on more trips and create more lifelong memories.

1. Get passports for everyone

If you're traveling internationally, remember that everyone needs a passport — even toddlers and babies. Getting a passport can take a while, so be sure to apply for your child's passport right away. Currently, posted passport processing times are as follows:

Routine processing: Seven to 10 weeks.

Expedited processing: Three to five weeks.

In extreme situations, you may be able to receive a same-day passport within three to five days of travel.

The U.S. Department of State has a handy tool that shows where you can apply in person for a passport based on your ZIP code. Both parents or guardians must be present when applying for a passport for children under 16 years.

Because kids grow and change quickly, children's passports are good for only five years and can't be renewed. This time frame is much shorter than the 10 years that adults enjoy with their passports.

2. Consider TSA PreCheck or Global Entry

TSA PreCheck and Global Entry are two examples of Trusted Traveler programs that allow flyers to move through airport security more quickly.

Children 12 and under can use the TSA PreCheck lanes when traveling with an eligible parent or guardian. Children 13-17 can as well but must have the TSA PreCheck icon on their boarding pass.

Global Entry, however, requires that every traveler be signed up, even young children. This nuance tripped us up when we were traveling home from Mexico when our daughter was 6 months old. Although it was an innocent mistake, the customs agent wasn't too forgiving.

TSA PreCheck is $78 and Global Entry is $100, and both memberships are good for five years. Global Entry includes TSA PreCheck and is highly recommended if it's possible that you'll travel internationally in the next five years. The time savings at customs is well worth the $22 price difference. Numerous travel credit cards reimburse cardholders for TSA PreCheck or Global Entry application fees. If you have multiple cards with this benefit, you can use a different card to pay for each of your family member's application fees.

3. Have a notarized letter for solo-parent travel

If one parent is traveling with your toddler while the other is staying home, it's important to get a notarized letter that confirms the non-traveling parent's permission. I travel frequently with my kids while my wife is at her 9-to-5 job, and this document has come up frequently on international trips.

4. Download apps and shows, charge devices

Before your trip, charge all of your electronic devices, including tablets, portable chargers and cameras. Many streaming services, like Netflix, Amazon Prime and Disney+, allow you to download movies and TV shows to watch when you're away from Wi-Fi.
