> Bring the bedtime routine, make the room dark, and use morning light to shift time zones. Use a safety-standard play yard with only its own mattress.

**Short answer:** Toddlers often sleep badly on vacation because everything that cues sleep has changed at once: the room, the light, the noise, the schedule, and sometimes the time zone. What helps most is bringing the familiar with you (the same bedtime routine, sleep sack, and white noise), making the room dark, and using daylight in the morning to shift their body clock. Keep the sleep space safe too: a play yard that meets federal safety standards, with only the mattress it came with and a fitted sheet.

Adam isn't a toddler yet, but our first big family trip is coming up, and I wanted a plan before we were stuck in a hotel room with a wide-awake child at 10pm. This is what I put together.

Key takeaways

- **Pack the routine:** same steps, same order, same sleep sack, same white noise.

- **Make it dark:** young children's body clocks are very sensitive to evening light.

- **Use morning daylight** to help shift to a new time zone.

- **Safe travel sleep:** a play yard or crib that meets federal standards, with nothing but its own mattress and a fitted sheet.

- **Expect a few rough nights** and return to normal habits once you're home.

## Why won't my toddler sleep on vacation?

Because their usual sleep cues are gone and their body clock may be out of step. Toddlers rely heavily on routine and familiar surroundings to wind down. On vacation, the room smells and sounds different, there may be light around the curtains, parents are in the same room, the days are exciting, and naps happen in strollers and cars. Any one of those can delay sleep. Together, they often add up to late bedtimes, night wakings, and early mornings.

- **New environment:** unfamiliar rooms make some toddlers more alert at bedtime.

- **Light:** hotel curtains and bright evenings outside can delay the body clock.

- **Sharing a room:** toddlers who can see or hear you often want to play.

- **Disrupted naps:** too little daytime sleep can leave them overtired; long late naps in the car can push bedtime later.

- **Time zones:** crossing even a couple of time zones can shift sleep and wake times.

## How do I get my toddler to sleep in a hotel room?

Recreate home as closely as you can. These steps are practical common sense rather than tested in trials, but they're built on what's known about routines and light:

- **Keep the bedtime routine identical.** Bath or wash, pajamas, teeth, book, song, lights out, in the same order you use at home. Our [toddler bedtime routine](/toddler-bedtime-routine/) guide covers the basics.

- **Bring sleep cues from home.** Their usual sleep sack, pajamas, a small comfort object if they're over 12 months, and the same white noise.

- **Make it dark.** Close the blackout curtains fully; some families pack portable blackout shades or use painter's tape on gaps. Keep screens and bright lights off in the hour before bed.

- **Create some separation.** Put the play yard in a quiet corner, or in a separate room of a suite where you can still hear your child. Keep it away from windows, blind and curtain cords, heaters, and balcony doors. A screen of luggage or a chair between the play yard and your bed can help, as long as nothing is within reach of the play yard.

- **Protect at least one good nap.** A nap in the play yard in a darkened room most days helps avoid a cycle of overtiredness.

- **Stay calm and consistent at night.** Respond the way you do at home. A little extra comfort is fine; new habits that you don't want to keep are easier to avoid than to undo.

The same bedtime steps, in the same order, are the most portable sleep cue you have.

## How do I help my toddler adjust to a new time zone?

Use light: bright light in the morning, dim light in the evening. The body clock is set mostly by light, and research in young children shows how sensitive they are to it. In a 2018 study in Physiological Reports, one hour of bright light in the evening suppressed preschoolers' melatonin, the hormone that signals night, by about 88%, and it stayed suppressed for at least 50 minutes after the light was turned off. A 2022 study found strong suppression even at fairly low light levels. Those children were preschool-age, so younger toddlers weren't tested, but the researchers describe young children's response to evening light as highly sensitive.

| Situation | What to try | Why | 
| 1–2 hour time difference, short trip | Many families keep roughly home time and shift meals and bedtime slightly | A small difference may not be worth fully adjusting | 
| Traveling east (clock moves later) | Morning daylight outside soon after waking; dim, calm evenings; wake your toddler at a reasonable local time | Morning light helps move the body clock earlier | 
| Traveling west (clock moves earlier) | Afternoon and early-evening daylight; push bedtime later in small steps | Later light helps move the body clock later | 
| Very early waking in a new place | Keep the room dark until your chosen wake-up time | Early light can lock in early waking | 
| Coming home | Same light rules in reverse; return to home routine right away | Gets the body clock back on home time | 

Shifting by an hour or so a day is a reasonable rule of thumb, though children vary. If the time change is small and the trip is short, keeping home time can be easier for everyone. Our post on [daylight saving time and baby sleep](/daylight-saving-time-baby-sleep/) uses the same principles for a one-hour shift.

**What the research says:** lab studies clearly show that young children's body clocks respond strongly to evening light. But there are no trials of jet lag or vacation sleep strategies in toddlers specifically. The advice here applies general circadian science and common practice. Don't give melatonin or sleep aids to help your toddler adjust without talking to your pediatrician first.

Bright morning light outdoors helps a toddler's body clock adjust to a new time zone.

## Is a hotel crib or play yard safe?

It can be, if it meets federal safety standards and is set up correctly. The AAP says to use a crib, bassinet, portable crib, or play yard that meets Consumer Product Safety Commission standards, and to check for recalls, especially on older units. Hotel cribs vary, so check before you use one:

- **Set up fully.** Every side locked in place, nothing sagging or broken, no missing parts.

- **Only the mattress it came with.** The AAP says a crib mattress should be designed for that crib and fit tightly. Don't add a second mattress, foam topper, folded comforter, or pillow to make a thin play yard mat "comfier"; extra padding creates gaps and soft surfaces.

- **Bare is best.** The CPSC's rule is nothing but a fitted sheet in a crib, bassinet, or play yard. Ask the hotel for a fitted sheet sized for the play yard, or bring your own.

- **No adult beds for babies.** Hotel beds have soft mattresses, pillows, and gaps. For babies under 1, the AAP recommends against bed-sharing.

For babies under 1, keep every travel sleep AAP-safe: on the back, firm and flat, fitted sheet only, no pillows, blankets, bumpers, or toys. Don't let your child sleep overnight in a car seat, stroller, or carrier; if they fall asleep in one, move them to a flat sleep space once you can. Toddlers who climb can tip or scale a play yard, so keep it away from windows, cords, and furniture, and see our post on a [toddler climbing out of the crib](/toddler-climbing-out-of-crib/). In the car, keep the harness snug; see [car seats and winter coats](/car-seat-winter-coat/) for cold-weather trips.

## What if my toddler won't sleep in the play yard at all?

Practice before you go. Many parents set the travel play yard up at home a week or two ahead and use it for a few naps, so it's already familiar. On the trip, put it in the darkest part of the room and keep your responses calm and boring. A toddler who protests on the first night often settles by the second or third.

Total sleep matters more than perfection on vacation. The American Academy of Sleep Medicine recommends 11 to 14 hours per 24 hours, naps included, for children 1 to 2 years old, and 10 to 13 hours for ages 3 to 5. A later bedtime one night, made up with a longer nap the next day, is fine.

Talk to your pediatrician if:

- sleep problems continue for several weeks after you're home

- your toddler snores loudly, gasps, or seems to pause breathing in sleep

- your child seems unwell on the trip: fever, ear pain after a flight, vomiting, or not drinking

- you're considering melatonin or any sleep aid

## Frequently asked questions

**Q: Can my toddler sleep in my bed on vacation?**

For babies under 1, the AAP recommends against it. For older toddlers, it's a family decision, but hotel beds can have gaps and drops, so think about falls, and remember new habits can follow you home.

**Q: Can I add a mattress pad to a travel play yard?**

No. Use only the mattress that came with the play yard, plus a fitted sheet made for it. Extra pads can create gaps and soft surfaces.

**Q: How long does it take a toddler to adjust to a new time zone?**

It varies. A common rule of thumb is about a day per hour of time difference, but there's little research in young children. Morning light speeds things along.

**Q: Should I keep my toddler on home time?**

For a time difference of an hour or two on a short trip, many families do. For bigger differences or longer stays, shifting to local time with light usually works better.

**Q: Will vacation ruin my toddler's sleep at home?**

Usually not for long. Go straight back to your usual routine when you get home, and most toddlers settle within a few nights to a week.
