Jet Lag in Children – How to Help Kids Adjust to a New Time Zone
Jet lag in children can feel like the thing that might ruin your entire trip before you even book the flight.
If you’ve ever struggled through daylight savings with a toddler, the thought of a 6, 12, or even 16-hour time difference can feel daunting. Jet lag with kids is real. It’s messy. It can mean middle-of-the-night wake-ups, dinner table face plants (seriously, true story), and trying to rally everyone when their bodies think it’s 3 a.m.
We’ve done 16-hour jumps to Asia more times than I can count. And even a 20-hour hop home from Fiji. We’ve had kids fall asleep mid-chew at dinner. We’ve had wide-awake toddlers at 2 a.m. pulling every single tissue out of the box.
And we still travel. Yes, it’s still worth it.
Because once you understand how to help kids adjust to a new time zone, and you have a simple plan, jet lag becomes something you manage, not something that manages you.
Let’s talk about how.

What Jet Lag Actually Is, In Normal Parent Terms
Jet lag happens when your internal body clock is out of sync with the local time.
Your body runs on a natural 24-hour rhythm called your circadian rhythm. It controls when you feel awake, when you feel sleepy, when you get hungry, and even how your hormones function. When you suddenly cross multiple time zones, your body is still running on “home time” even though the clock says something completely different.
Kids feel this just like adults do. Sometimes even more intensely.
That is why your child might:
- Wake up wide awake at 2 a.m.
- Crash at 5 p.m.
- Refuse breakfast because their body thinks it is the middle of the night
- Melt down at what is technically 10 a.m. but feels like bedtime
The good news is this. The body wants to reset. It just needs strong cues.
And the strongest cue of all is light.
Natural daylight, especially in the morning, tells the brain what time it is. Food timing, movement, and bedtime routines also help. When you use those cues intentionally, you can shift your child’s internal clock much faster than if you just let things drift.
That is where the system comes in.
The 24-Hour Reset Method for Jet Lag in Children
This is the approach we use every time we cross major time zones. It is not perfect. Sorry, it’s not magic. But it works most of the time. When it doesn’t, it still shortens the adjustment period.
The goal is simple. Get on the local time as quickly as possible.
Step 1: Switch to destination time immediately
The moment you land, you are on local time. Mentally and practically.
If you wear a watch that does not auto-update, change it before you even get off the plane. Stop calculating what time it is back home. Stop saying “Well in Seattle it’s…” That keeps your brain stuck.
You are not in your old time zone anymore. Your body might be, but your schedule is not.
This mental shift matters more than people think.
Step 2: Use light like a cheat code
Light is the most powerful reset button you have.
On your first morning in your destination, get outside as early as you reasonably can. Even if everyone feels groggy. Even if you slept terribly. Even if it is cloudy.
Outdoor light, even on overcast days, is significantly brighter than indoor light. That brightness signals to the brain that it is morning and helps shift the internal clock.
Here are easy ways to do this with kids:
- Walk to a bakery and eat outside
- Go straight to a park or playground
- Sit at an outdoor café
- Take a stroller walk through a neighborhood
- Do a simple walking tour
- Head to the beach or pool if that fits your destination
Movement helps too. You do not need an intense day one itinerary. But staying active, upright, and exposed to daylight helps your body reset faster.
Step 3: Cap naps and protect bedtime
This is the slippery slope.
If you land in the morning and everyone is exhausted, it will be tempting to take a “quick nap.” The danger is that the quick nap turns into a full night of sleep at 2 p.m. local time.
If you truly cannot power through, take a nap. But cap it.
Ideally, 30 minutes. At most 90 minutes. Set multiple alarms. Put one across the room so you have to stand up to turn it off.
For babies and toddlers who still nap regularly, do not eliminate naps completely. That usually backfires. Instead, aim for naps on the go the first day or two. Stroller naps, carrier naps, beach tent naps. The light and ambient noise reinforce that it is still daytime.
Then protect bedtime. Dim the lights. Do your normal bath, book, song routine. Use a sound machine if you normally do at home. The familiarity signals that it is nighttime, even if the location is new and timing feels different.
Step 4: Keep day cues and night cues clear
Kids rely heavily on routine.
Even on travel days, try to:
- Eat breakfast, lunch, and dinner at normal local times
- Get outside during daylight
- Keep evenings calmer and dimmer
- Follow a recognizable bedtime routine
What does not work well is hiding inside all day because you are tired, skipping meals, or abandoning structure completely. That tends to prolong jet lag in children rather than shorten it.
You are not aiming for perfection. You are aiming for clear signals.
Your Jet Lag Game Plan by Landing Time
Not all arrivals will be the same.
The time you land can either make adjusting to a new time zone much easier… or much harder. We have done enough long-haul flights to know this makes a big difference.
Here is how to handle each scenario.
If you land in the morning
This is the hardest version.
If you land at 7 a.m. local time but your body thinks it is 3 p.m. yesterday, you are staring down a very long day.
Here is the plan:
- Get outside as soon as you can.
- Keep everyone moving.
- Eat on local time, even if no one is very hungry.
- Avoid a full, dark-room nap.
If someone truly cannot function, allow a short, capped nap. Set alarms. Keep it under 90 minutes. Ideally, closer to 30 to 45 minutes.
The goal is to make it to a reasonable local bedtime. Not midnight. Not 5 p.m. Something in the normal range.
This is the day that requires grit to get through it. But when you push through successfully, you often wake up the next morning surprisingly close to normal.
We have powered through mornings like this before. It is rarely pretty. But it is possible.
If you land in the afternoon
This is my personal favorite.
Landing in the late afternoon or early evening feels like the sweet spot for families. You are tired enough to want sleep, but not so destroyed that you cannot function at all. And the adrenalin of being in a new place keeps you going for a little bit.
Here is the plan:
- Get settled.
- Get a simple dinner.
- Explore just a bit.
- Do your normal bedtime routine.
- Go to sleep at a typical local bedtime.
This is the arrival that most often results in a one-day adjustment for us. When everything lines up and everyone is just tired enough, you sleep a real night in a real bed on local time and wake up ready to go.
If you have flexibility when choosing flights, this is the arrival window I prefer.
If you land at night
This can go two ways.
If everyone didn’t get much rest on the flight and it is truly late at night when you land, go straight to sleep. Do not start exploring. Do not get “second wind” energy and unpack for two hours.
Protect sleep.
If everyone is overtired and unraveling, keep things simple. Minimal lights. Minimal stimulation. Quick bedtime routine. Sound machine if you use one.
If everyone is wired and awake, ready to go, this is tough. Try to go out for some light food and stimulation if things are open. Let the dark cue your body. Then return to your hotel and start a nighttime routine.
The key is not pushing bedtime later and later even if you feel awake. Because you need to reset and start on local time in the morning.
A real-life example
When we took our daughter to Seoul for her first big international trip, the time difference was extreme. She woke up the first few nights in the middle of the night as if it were morning.
It was not ideal. It was not fun and games.
I kept the lights low. I let her quietly play with a tissue box as I drifted in and out of sleep. And then woke up to 100 tissues all over the floor. I rotated through a few quiet plane toys. I did not turn on bright lights. I did not change her outfit. I did not start the day.
Within a few days, her body caught up.
It was messy, but we managed.
And it did not ruin the trip.
East vs West Travel with Kids
You are not imagining it.
For most people, traveling east is harder than traveling west.
There is real biology behind that.
Your internal body clock naturally runs slightly longer than 24 hours. That means it is easier for your body to stay up later than it is to fall asleep earlier. Traveling west usually requires you to delay sleep. Traveling east usually requires you to advance it.
Delaying is easier. Advancing is harder.
That is why flying from the U.S. to Europe often feels brutal. You lose hours and are expected to fall asleep earlier than your body wants to. Flying west tends to feel more forgiving because you are allowed to stay up later.
But here is where it gets interesting.
Why Asia can feel easier, even with a huge time difference
We have done 16-hour jumps from Los Angeles to Taipei and Tokyo multiple times. Technically, that is an enormous shift. And yet, for our family, it often feels easier than flying to Europe.
Why?
A few reasons:
- Sometimes a very large time difference effectively “flips” your schedule in a way that aligns better with daylight.
- If you land in the late afternoon or evening, the timing works in your favor.
- You are often so sleep deprived that sleeping at local bedtime feels natural.
- There is usually strong morning light exposure the next day, which helps anchor the new schedule quickly.
In contrast, traveling east often requires trying to sleep when your body is wide awake and ignore early morning wake-ups when your body thinks it is mid-afternoon.
That does not mean westbound travel is easy. It just tends to be more forgiving.
What this means for families
If you are traveling east:
- Expect it to feel harder.
- Prioritize morning light immediately.
- Keep naps short.
- Be extra protective of bedtime.
If you are traveling west:
- You may find it easier to stretch the day.
- Be careful not to let kids stay up wildly late multiple nights in a row.
- Still use light intentionally to anchor mornings.
Either direction, the same core rules apply. Light. Local time. Capped naps. Clear routines.
And flexibility.
What To Do When It’s Cloudy or Raining
Parents ask this all the time.
If light is the key to resetting jet lag in children, what happens when you land somewhere gray and rainy?
Go outside anyway.
Even on a cloudy day, outdoor light is dramatically brighter than indoor light. Your brain does not just respond to sunshine. It responds to brightness. Natural daylight, even filtered through clouds, is still one of the strongest signals your body receives about what time it is.
That signal travels from the eyes to the brain’s internal clock and helps reset your circadian rhythm. Morning light is especially powerful for anchoring a new schedule.
So if it is raining:
- Put on jackets and walk anyway.
- Sit under a covered patio.
- Explore a neighborhood on foot.
- Visit an outdoor market with umbrellas.
- Walk to coffee instead of driving.
You do not need to be sunbathing. You just need exposure to real daylight.
If the weather is truly awful and you cannot be outside for long, try to:
- Get outside briefly in the morning.
- Spend time near windows.
- Keep indoor lights bright during the day.
- Dim lights noticeably in the evening.
The goal is contrast. Bright during the day. Dim at night.
That contrast and gradual change from bright to dark helps your child’s internal clock shift faster than if you stay inside under the same lighting all day.
Age-Based Tweaks for Jet Lag in Children
The core strategy stays the same no matter how old your child is. Light. Local time. Capped naps. Clear routines.
But how you apply it looks different depending on age.
Babies and toddlers
This is, understandably, usually the stage parents worry about most.
Babies and toddlers have less awareness of time, but they are deeply wired to routine and sleep pressure. That means two things are true at once. They can adjust quickly. And they can unravel quickly.
A few practical tweaks:
- Do not eliminate naps completely. That often backfires.
- Aim for naps on the go during the first couple of days.
- Keep bedtime cues consistent, even in a new environment.
- Keep night interactions calm, quiet, and dim.
When we took our daughter to Seoul for her first long-haul international trip, the time difference was significant. For the first few nights, she woke up in the middle of the night as if it were morning.
It was not peaceful. I questioned my life choices. But I kept steady and reminded myself what I know to be true.
I kept the lights low. I handed her a tissue box and let her pull out every single tissue one by one. I rotated through a few quiet plane toys. I did not turn on bright lights. I did not signal that the day had started.
Within a few nights, her body caught up.
Was it perfect? Not even close. Was it survivable? Absolutely.
The key is this. If your baby wakes at 2 a.m., do not panic. Keep it boring. Keep it dim. Keep it short. The more you treat it like nighttime, the faster their body learns.
Big kids
Big kids can power through longer stretches without naps, but they can still struggle with major time shifts.
You may see:
- Dinner table crashes
- Emotional swings
- Early morning wake-ups
- Refusal to get moving in the morning
The temptation with big kids is to let them nap freely because they seem so exhausted. But unlimited afternoon sleep is one of the fastest ways to prolong jet lag with kids.
If they truly need a nap:
- Cap it.
- Set alarms.
- Wake them up even if they are grumpy.
It feels mean in the moment. But it pays off at bedtime.
Big kids can also understand what is happening. Explaining that “our bodies are confused but we’re helping them adjust” actually helps. Give them ownership. Let them help track local time. Let them help choose an outdoor morning activity.
When they feel involved, they tend to cooperate better.
Parents
If the parents fall apart, the whole system falls apart.
You are adjusting too. And often you are running on even less sleep than anyone else because you are managing it all.
A few reminders:
- Follow the same light rules yourself.
- Avoid scrolling in bright light at 2 a.m.
- Eat on local time even if you are not hungry.
- Resist the urge to take a four-hour afternoon nap.
We have occasionally used melatonin for older kids when adjusting back home, usually for the first one or two nights. Not on the way to a destination. And only after discussing it with our pediatrician. I would never rely on it as the entire plan.
The foundation is still light, movement, and schedule cues.
You do not need perfect sleep on night one. You need directionally correct sleep. Improvement each day.

What Not To Do When Dealing with Jet Lag in Children
Sometimes it is easier to see what works by understanding what makes it worse.
Here are the mistakes that tend to prolong jet lag with kids.
Do not stay on “home time”
Constantly calculating what time it is back home keeps everyone mentally anchored to the wrong clock.
The second you land, you are on local time. Stop saying, “Well in New York it’s…” Your body might still be confused, but your schedule is not.
Living in two time zones at once slows adjustment.
Do not let a “quick nap” turn into five hours
This is the fastest way to get stuck.
You land exhausted. You lie down “just for a minute.” Suddenly it is 8 p.m. and your child has slept for five straight hours.
Now they will be wide awake at midnight.
If you need a nap, cap it. Set multiple alarms. Wake everyone up even if it feels cruel in the moment. A short-term grumpy afternoon is better than three more nights of chaos.
Do not hide indoors all day
It is tempting to take it easy inside when everyone feels off.
But staying under the same indoor lighting from morning to night blurs the signals your body needs to reset. Bright daytime exposure and dim evenings create contrast. That contrast helps shift the internal clock.
Even if it is cloudy. Even if it is chilly. Get outside.
Do not overschedule the first day
There is a balance.
You want movement and light. You do not want a packed itinerary with museum tickets, timed entries, and zero margin.
Keep day one simple. Walkable. Flexible. Easy to abandon if needed.
Think playground, neighborhood stroll, outdoor café. Not a three-hour guided tour, the attraction you’re most excited about, and a special dinner reservation.
Do not expect perfect sleep on the plane
This one matters.
If you go into a long-haul flight assuming everyone will get a full, normal night of sleep, and be ready to roll in the morning all day, you will be disappointed. Plane sleep is rarely high quality. Even when kids sleep, it is not the same as a real bed for a full night.
Plan for imperfect sleep. Build your adjustment strategy around that reality.
Do not panic over one rough night
One bad night does not mean the trip is ruined.
We have had middle-of-the-night wake-ups in Seoul. Dinner table crashes in Dubai. Emotional mornings in Romania. And then the next day was better.
Jet lag in children usually improves quickly when you give clear signals and stay consistent. The body wants to adjust.
FAQs About Jet Lag in Children
How long does jet lag last in children?
Jet lag in children typically lasts one to three days when you actively help them adjust. Large time differences, like 12 to 16 hours, may take a little longer. Using strong daylight exposure, capping naps, and sticking to local meal and bedtime routines can significantly shorten the adjustment period. If you don’t actively work to adjust, it can take longer.
Is traveling east harder than traveling west for kids?
Yes, for most families, traveling east feels harder. The body naturally finds it easier to stay up later than to fall asleep earlier. Eastbound travel usually requires kids to go to bed earlier than their internal clock wants to, which makes adjusting tougher. Westbound travel tends to feel more forgiving.
How do you handle a 12-hour or 16-hour time difference with kids?
The strategy stays the same even with big time jumps. Switch to local time immediately, prioritize morning daylight, keep naps short, and protect bedtime. Large shifts can feel dramatic at first, but when you use strong light cues and consistent routines, most kids adjust surprisingly quickly.
What if my child wakes up at 2 a.m. every night on vacation?
Treat it like nighttime. Keep lights low. Keep voices quiet. Offer calm, boring activities if needed, but do not signal that the day has started. Avoid bright screens or overhead lights. Consistency matters. Within a few days, most children’s internal clocks will catch up.
Should kids take melatonin for jet lag?
Some families consider melatonin for short-term schedule adjustments. Always talk with your child’s pediatrician first. If you want to try it, test it at home before relying on it during travel. Melatonin should support a strategy built on light and routine, it won’t work miracles alone.
Does rainy or cloudy weather make jet lag worse?
Not necessarily. Outdoor light is still significantly brighter than indoor light, even on cloudy days. Getting outside in the morning and during daylight hours still helps reset the body clock. You may just need a little more time outdoors compared to a bright sunny day.
Is jet lag worse for babies than older kids?
Babies can actually adjust quickly because they are not as mentally attached to a clock. The challenge is that they rely heavily on sleep pressure and routine. Keeping naps, bedtime cues, and light exposure consistent helps them shift. Older kids may complain more, but the biology is similar.
Jet Lag Does Not Have to Stop You From Traveling
Jet lag in children can feel intimidating before a big trip. It is unpredictable. It can throw off sleep, moods, and meals for a few days.
But it is temporary.
We have crossed extreme time differences, adjusted back home after long-haul trips, and navigated the occasional 3 a.m. wake-up call. None of it was perfect. All of it was workable.
What makes the difference is having a plan.
When you anchor to local time, prioritize daylight, keep naps in check, and protect bedtime, you shorten the adjustment window. You give your child’s body clear direction instead of mixed signals.
Most families find that improvement happens quickly. Not instantly. But steadily.
Jet lag with kids is a short transition.
And once you are on the other side of it, you are exactly where you wanted to be in the first place. Exploring somewhere new together. It’s worth it.
