How do I handle jet lag with toddlers?

Shift their schedule by 30-60 minutes each day for 3 days before you leave. Upon arrival, get them into natural sunlight immediately to help reset their internal clocks.

Should I bring a car seat?

Only if you plan to rent a car or take private taxis. If you are sticking to public transit, avoid it—it is one extra heavy item to lug through airports.

Planning an International Trip with Young Children

Plan no more than one activity per day and prioritize direct flights to minimize travel stress. Stick to your home routine as much as possible, including nap times and meal structures, to help children adjust to time zone changes.

Choose a kid-friendly destination. Pick locations with high walkability, reliable public transportation, and a culture that values families, such as Japan, Denmark, or Costa Rica.
Prioritize direct flights. Even if it costs $200 more, avoid layovers. If a long-haul flight is unavoidable, book an overnight flight to maximize the chance of children sleeping.
Book apartments over hotels. Rent an Airbnb or serviced apartment with a kitchen and a separate bedroom. Having a fridge for milk and space to hang out after the kids go to sleep at 7:30 PM is essential.
Adjust the itinerary speed. Plan only one 'anchor' activity per day. Expect to be back at your accommodation for nap time or early bedtime. Anything else is a bonus.
