Traveling to Korea with a baby: what to check before you fly
You packed well. Flights, hotel, the snacks that stop a meltdown on hour eleven. And then you land at Incheon and start learning things you’d rather have known in your own living room. That your baby needed her own entry declaration. That the rental car you booked doesn’t come with a car seat, and the fine is yours, not theirs. That pharmacies close on Sundays. That the bottle sterilizer you carried across an ocean makes a burning smell the moment you plug it in.
This isn’t a list of things to rent. It’s a list of things to check — the nine points where families traveling with children aged 0 to 6 actually get caught out in Korea, and how to deal with each one before you’re standing in an arrivals hall with a tired toddler.
At a Glance Nine things to confirm before you fly to Seoul with a small child: ① children 17 and under are exempt from K-ETA, but your baby still files a separate e-Arrival Card ② if you’re driving a rental car, a car seat is legally required under age six and the fine lands on the driver ③ the subway and city buses are free for under-sixes, three per adult ④ bring specialty formula in full, buy ordinary diapers and formula here ⑤ for a sick child at night, the answer is a Moonlight Children’s Hospital, not an ER ⑥ Korea is 220V/60Hz — leave baby appliances at home.

01Paperwork
Your child skips K-ETA — but not the entry declaration
This is where most families trip, because the two systems sound like one.
K-ETA is waived for everyone aged 17 and under. Nationality doesn’t matter; if your child is 17 or younger on the date of entry, there is nothing to apply for. Newborn or five-year-old, same answer. A surprising number of English-language guides insist that “even infants need their own K-ETA.” They’re wrong.
The catch is what comes next. Under the Ministry of Justice’s rules, travelers who are exempt from K-ETA are required to submit the e-Arrival Card. So a parent holding a K-ETA is excused from the declaration, while the child who was excused from K-ETA is not. You will be filing an extra entry declaration, with your baby’s passport in your hand.
The e-Arrival Card is free, can be submitted from three days before arrival, and stays valid for 72 hours. A desktop browser handles up to 1,000 people in one go; mobile web caps out at nine. Do it the night before, passports spread across the bed, and get all of it done at once.
One more thing worth checking: the temporary K-ETA waiver for a list of countries — including the US, Canada, the UK, Australia, New Zealand and Japan — has been extended through 31 December 2026. Rather than trusting a number you read in a blog, scan your passport on the official K-ETA site; if you’re covered, it tells you so.
02Driving
If you’re renting a car, the car seat isn’t optional
Korean road traffic law requires an approved child restraint for any child under six. Not only on expressways — every road, every seat. And the penalty is written against the driver, not the passenger: failing to secure a passenger under 13 carries a ₩60,000 fine.
Which makes the important question who is driving. The moment you take the wheel yourself — a rental car from the airport, a friend’s car for the weekend — the responsibility is entirely yours. Collecting a rental at Incheon on day one, a day trip out to the coast, a run to an outlet mall or a theme park: if there’s any chance you’ll be driving with your child, sort the car seat out before you land.
Rental branches at Incheon Airport and in central Seoul do sometimes offer child seats, but allocation is capped per booking and stock varies by vehicle class and location. Every year, families hear “sorry, none available” at the counter and rearrange their itinerary around it.
That leaves two realistic options.
- Bring your own. Most airlines check a car seat free of charge. The trade-off is real, though — cargo holds crack shells and snap buckles, hauling one through a terminal alongside a stroller and two suitcases is miserable, and you’ll typically use it on one or two days of a two-week trip.
- Rent it here, for the days you drive. KPLANZ keeps two, collected at Hongik Univ. Station Exit 3.

03Public transport
Kids ride free. The elevators are a different question.
Children under six travel free on the Seoul subway and city buses — up to three per accompanying adult, with no card and no ticket. You tap, they walk through the wide gate beside you. From six to twelve they need a transport card registered with their date of birth at a convenience store counter; skip that step and the machine quietly charges the adult fare all week.
Long-distance trains follow the same logic. On KTX, one child under six travels free per adult as long as they don’t occupy a reserved seat. Want the child in their own seat? That’s a discounted fare. Ages six to twelve pay the child fare.
Step-free access has genuinely improved — but not everywhere you’ll be riding. In December 2025 Seoul completed its “one barrier-free route per station” program across all 338 stations on the lines the city operates, meaning an elevator path from street to platform without stairs. For anyone pushing a stroller, that’s a different city than it was five years ago. The caveat: those 338 are Seoul-operated lines. Korail-run metropolitan lines — including the Airport Railroad (AREX) from Incheon — aren’t part of that count. Which is, of course, exactly the line you take on day one.
Seoul Metro’s own safety guidance is explicit: taking a stroller onto an escalator is dangerous, and it’s prohibited on single-width escalators. You will absolutely see people doing it anyway. Find the elevator. Bringing an unfolded stroller onto the train itself is completely fine — there’s no rule against it.
If day one is what worries you, the simplest version is this: AREX from Incheon straight to Hongik Univ. Station with no transfers, then collect the stroller and car seat at Exit 3 before you go anywhere else. Visit Us has the walk mapped out with photos.
04Strollers
Bring or rent — just decide on the right criteria
We’ve covered the full argument in Do you need a stroller in Seoul? and the cost comparison in Renting vs buying baby gear. Here, only the things to check before you fly:
- Walking age and vacation pace are different things. A Seoul sightseeing day runs six hours and several kilometers without trying. The four-year-old who walks happily at home gives out around two in the afternoon.
- With two kids, two strollers from home is rarely realistic. Bringing one and renting the second on arrival is the most common fix.
- Check the ground. Large parts of Gyeongbokgung and the other palaces are gravel and packed dirt. Small-wheeled ultralight strollers struggle there.
- Check the season. From late June to late July, a stroller rain cover matters far more than an umbrella.

05Feeding
Buy diapers and formula here. Bring specialty formula in full.
For ordinary baby supplies, Korea wins easily. There is no reason to fill half a suitcase with diapers.
- Diapers. Huggies, Pampers, Goon and Korean brands are everywhere at E-Mart, Homeplus and Lotte Mart — roughly ₩22,000–33,000 for a pack of 42–72. Convenience stores (GS25, CU, 7-Eleven) sell three- and five-packs at bad value; treat those as emergency supply, not a plan.
- Formula. Korean brands run about ₩23,000–32,000 for an 800 g tin, and imported names like Aptamil are available. But scoop sizes and mixing ratios differ by country. Switch brands mid-trip and your child’s stomach registers the change before you do. Carry at least several days of what they already drink.
- Specialty formula: bring the entire trip’s supply. Hydrolyzed and amino-acid-based formulas are stocked very thinly in Korea and are effectively unavailable in ordinary supermarkets. This is not a “we’ll find it there” situation.
- Baby food. Supermarkets carry a wide pouch selection, and convenience-store juk (rice porridge) and instant rice are genuinely useful fallbacks.
Don’t count on Coupang. The app has an English beta and will deliver to a hotel, but checkout is wired into Korean identity verification — a Korean phone number, a domestic card, a local bank account. Overseas cards sometimes clear and often don’t. One supermarket run on day one or two is the reliable version.
Finding a nursing room. Department stores are the gold standard — private nursing booths, changing tables, hot water, microwaves, and in the best of them a nap room. Large attractions run them too, though most don’t stock diapers, so carry your own. Nationwide, the health ministry’s directory at sooyusil.com maps nursing facilities; in Seoul, the Smart Seoul Map has a dedicated nursing-facility layer. Both are Korean-language, so turn on your browser’s translation before you need them in a hurry.
06When they get sick
At night, the answer is a Moonlight Children’s Hospital — not an ER
Children spike fevers on holiday. Knowing what happens next makes the night survivable.
Real emergency: 119. It’s the combined fire and ambulance number, and ambulance transport is free. Say “English, please” as soon as it connects and an interpreter joins the call.
Not an emergency, but you can’t communicate: 1330. The Korea Tourism Organization’s 24-hour multilingual line will interpret live. Put it on speaker at a hospital reception desk and most problems dissolve.
1339 is not a medical helpline. It’s the disease control agency’s call center. Calling it about a sick child gets you nowhere.
달빛어린이병원 — “Moonlight Children’s Hospital” — is the one to know. These are government-designated night and holiday pediatric clinics: 152 nationwide as of June 2026, open until roughly 23:00–24:00 on weekdays and 18:00 on weekends and public holidays, treating patients aged 18 and under. Fever, colds, vomiting, diarrhea, ear infections. Cheaper and faster than an emergency room, and staffed by pediatricians. Individual sites do suspend hours without notice, so call before you set out.
🏥 Open hospitals and pharmacies right now: e-gen.or.kr 💊 holiday pharmacies: pharm114.or.kr 🕐 call ahead either way
Pharmacies close earlier than you expect. Typically 09:00 to 18:00 or 19:00 on weekdays, until 1 or 2pm on Saturday, and closed Sunday and public holidays. For a 3am fever, go to a convenience store — children’s Tylenol is on the approved 24-hour list. One Korean phrase covers it: 어린이 해열제 (eorini haeyeoljae, children’s fever reducer).
Costs and insurance. Visitors staying under 90 days aren’t covered by Korean national health insurance, so you pay 100%. A neighborhood clinic runs roughly ₩10,000–30,000; a hospital emergency room can reach ₩200,000–500,000 and beyond. Treat travel insurance as baseline, not optional.
Worth knowing too: Korea’s pediatric emergency capacity has been under strain since 2024 and hasn’t fully recovered. For anything mild, use clinic hours or a Moonlight clinic rather than an ER. For something serious, call 119 and let the paramedics find the receiving hospital — that’s faster than driving between them yourself.
07Electricity
220V/60Hz — leave the baby appliances at home
This is the lesson travelers pay the most for.
Korea runs on 220V/60Hz. If you’re coming from a 110V or 100V country, plugging your device into a shape-changing plug adapter can destroy it. An adapter changes the pins. It does not change the voltage. Anything that isn’t marked dual-voltage needs an actual transformer.
Bottle sterilizers, bottle warmers, baby food makers, humidifiers, kettles — all of them. Heavy, bulky, and one wrong socket from being finished.
Which is why baby appliances are the clearest case for renting. Everything KPLANZ stocks is a native 220V Korean unit: plug it in and it works.
₩15,000/day · Upang UV bottle sterilizer, 220V/60Hz · ₩300,000 deposit
₩15,000/day · BabyBjörn Travel Cot Light, 6 kg, folds flat · ₩150,000 refundable deposit
Hotel cribs are frequently promised and occasionally delivered, and Seoul rooms are small. Reserving a travel cot in advance is what makes the first night calm.
08Eating out
“No kids zones” are rarer than the internet suggests — but they cluster where you’ll be
A civic-group survey conducted between September and December 2025 and published in January 2026 counted 114 no-kids zones nationwide, with the campaign’s public map listing 122 by May 2026. Against the total number of food businesses in Korea, that’s small. The distribution is the problem: nearly half sit in Seoul and Gyeonggi, and 74% of them are cafés. Which is to say, precisely the places you duck into when a small child needs twenty minutes and a juice.
There’s no official registry. Three ways to check: the notice at the door, the listing on Naver Map or Kakao Map (and often the venue’s Instagram bio), and the campaign’s crowd-sourced map at nokidszoneout.kr. Pushing the other direction, Seoul city certifies child-welcoming venues as “Seoul Kids OK Zones,” searchable on the Smart Seoul Map.
The move that never fails is a department store restaurant floor. Lotte, Shinsegae and Hyundai all put dining on their upper floors: room for a stroller, high chairs, English menus, and a nursing room with a changing table on the same level. With a toddler, that combination is very hard to beat.
On spice. “Not spicy” is relative here — gochugaru and gochujang turn up in side dishes you didn’t order. Two sentences carry you: “안 맵게 해주세요” (an maepge haejuseyo, please make it not spicy) and “아이가 먹을 거예요” (aiga meogeul geoyeyo, it’s for a child). Reliable wins: gimbap, mandu, juk (chicken or vegetable porridge), steamed egg, bulgogi, japchae. And asking for scissors to cut it up is completely normal — that’s how Koreans eat it too.
09Weather
Fine dust, heat, and the rainy season decide your daily plan
Fine dust (December–March). The government runs a Fine Dust Seasonal Management System from 1 December to 31 March every year. Winter and spring are the bad months, March worst of all. Check live readings and forecasts at airkorea.or.kr, or cleanair.seoul.go.kr for the city. PM2.5 at 36 or above is graded “Bad” — a good trigger to swap the day for an aquarium, a museum or an indoor play café. KF94 masks are sold in every convenience store and pharmacy, child sizes included.
Summer (June–August). Korean heat alerts are based on perceived temperature, not air temperature (advisory at 33°C, warning at 35°C). With Seoul’s humidity, a 33°C day feels past 38°C. From 1 June 2026 the meteorological administration restructured the system for the first time in 18 years, adding a new top tier. Seoul’s first heat advisory of 2026 came on 18 June, twelve days earlier than the previous year. With a small child, treat 10:00–16:00 outdoors as something you plan around, not through.
Rainy season (late June to late July). Central Korea’s monsoon normally starts in late June and ends in late July, though the weather agency stopped forecasting the start and end dates back in 2009 because heavy rain now falls well outside the window. If those are your dates, a stroller rain cover and a spare change of clothes beat an umbrella every time.
The pre-flight checklist
Documents. Child’s passport · a separate e-Arrival Card for the child · travel insurance certificate
Legal. Driving a rental car? Secure a car seat for any child under six — the fine falls on the driver
Medical. Save 119 and 1330 · locate the Moonlight clinic nearest your accommodation · pack fever reducer and a thermometer
Supplies. Specialty formula in full · ordinary diapers and formula after you land
Power. Baby appliances stay home — rent 220V units here
Booking. In peak season (April–May, September–October, Korean holidays) strollers and car seats go first. Ask at least 48 hours ahead, ideally two weeks.
Reserving takes one message
A stroller, a car seat, a sterilizer and a travel cot can all go on one booking, collected in one stop at the building directly connected to Hongik Univ. Station Exit 3 — indoors the whole way, rain or shine.
