How Do You Help Children With Jet Lag?

Why Jet Lag Hits Kids

Jet lag happens when your child’s body clock is still set to home time while the clock on the wall says something else. Hunger, sleepiness and energy all arrive at the wrong hours until the body catches up.

Kids feel it differently from adults. They may not say they are tired, but you see it in crankiness, early wakeups, poor appetite at meals and sudden energy at bedtime. A common rule of thumb is roughly one day of adjustment per time zone crossed.

East vs. West

The direction of travel changes how hard the adjustment is. Flying east is usually harder than flying west.

• Flying east (for example, New York to Paris) means bedtime arrives earlier than your child’s body expects. Falling asleep early is harder than staying up late.
• Flying west (for example, Chicago to Hawaii) means staying up later. Most kids find this easier, though early morning wakeups are common for the first few days.

Light is the main tool either way. Morning light helps the body shift earlier, which helps with eastward trips. Afternoon and evening light helps the body shift later, which helps with westward trips.

A Plan by Time Difference

The size of the time difference decides how much preparation is worth it. Small shifts need almost nothing, while big ones benefit from a few days of prep and a patient first week.

These ranges are estimates, not guarantees. Some kids bounce back in a few days, while others need the full stretch.

Shift Bedtime Before You Go

Shifting bedtime a little each day before the trip gives your child a head start. Move bedtime, wake time and meals 15 to 30 minutes a day for a few days.

• Going east: move everything earlier. Wake them a bit earlier and open the curtains right away.
• Going west: move everything later. Keep evenings bright and push dinner back.
• Do not overdo it. A tired, overshifted child starts the trip worse off. Even 1 hour of shift before departure helps.

For small differences of 1 to 2 time zones, you can skip this step.

Pick Flight Times That Help

Flight timing can do a lot of the work for you. For long eastward trips, an overnight flight is often the best choice.

• Overnight flights let kids sleep through part of the journey. Keep the usual bedtime routine on board: pajamas, a book, a familiar blanket or toy.
• Daytime westward flights often line up with arriving in the local evening, which makes the first bedtime easier.
• Set watches and devices to destination time once you board, and start talking in local time.

Babies and toddlers bring their own challenges on long flights. See our guides to flying with a baby and flying with a toddler for sleep, feeding and seating tips.

Use Light and Meals on Arrival

Daylight is the strongest signal for resetting a body clock. Get outside as much as you can during the first few days.

• After an eastward trip, get morning light. A walk, a playground or breakfast outdoors all count.
• After a westward trip, get afternoon and early evening light to push bedtime later.
• Keep the room dark at night. Blackout curtains or a portable blackout blind help, especially in summer.

Meal times are the second signal. Eat on local time from the first day, even if appetites are off. A small, plain snack is fine when hunger strikes at odd hours, but save full meals for local breakfast, lunch and dinner.

Arrival Day Naps

Naps on arrival day are the most common place where jet lag plans fall apart. The fix is to allow a short nap but cap it.

• Older kids: about 20 to 45 minutes in the early afternoon, then wake them.
• Toddlers: keep the usual nap, but end it by mid-afternoon local time.
• Babies: follow their normal nap rhythm on local time as closely as you can.
• Avoid late naps. A nap after about 4 p.m. local time usually costs you bedtime.

Waking a sleeping child feels harsh. It usually makes the first night much easier.

The First Few Nights

Night wakeups are normal for the first 2 or 3 nights, especially after eastward trips. Treat them like any other middle-of-the-night wakeup.

• Keep lights off or very dim, and avoid screens.
• Talk in a whisper and keep it boring.
• Offer water or a small, plain snack if hunger is waking them.
• If they are wide awake for an hour or more, quiet activities in low light, then try again.

Do not let the next morning’s wake-up slide past local time. A normal morning start is what fixes the following night.

Babies vs. Older Kids

Age changes how you manage jet lag. Babies and toddlers depend more on your routine, while older kids can work with the plan.

• Babies often adjust fairly quickly because they sleep in shorter blocks anyway. Shift feeds toward local times gradually, and keep the bedtime routine identical to home.
• Toddlers feel it most in their mood. Protect naps, stick to familiar routines, and bring their usual sleep items.
• School-age kids and teens can understand why they need to stay up or get outside. Give them a job, like tracking daylight hours or planning the morning walk.

If your child has a health condition or you are unsure about sleep, ask your pediatrician before the trip. Never give melatonin or other sleep aids without their guidance.

Short Trips and Coming Home

For short trips, staying on home time is often easier than adjusting. On a trip of about 3 days or less with a small time difference, keep bedtime roughly the same and shift activities around it.

Coming home needs its own plan. The return adjustment follows the same rules, in the opposite direction.

• Shift bedtime toward home time for the last 1 to 2 days of the trip.
• Leave a buffer day before school or daycare if you can.
• Get outside at home in the right light window for the direction you flew.

Building in buffer days costs little and saves a lot of tired mornings. For more ways to keep trips simple and affordable, see family travel on a budget, and use the packing list generator to bring the sleep items that make a new room feel familiar.
