Take it from a dad in the know. The writer of Dadsolo.com has a helpful article for family travel. Read the article below.
Also, I think you’ll like BabyQuip, a one stop online shop for equipment rentals for your littles. You may book online yourself, or if you have a complex itinerary you may send them your itinerary along with the ages of your kids and the equipment you’ll need. They’ll take care of the rest, including delivery, set up, and pick up!
