Going on holiday with kids can be great fun—but let’s be honest, it can also be a bit of a faff if you’re not on top of the paperwork. Sorting out the right travel documents before you go isn’t just a good idea, it’s a must. Whether you’re off to the sunny beaches of Spain or exploring the streets of Tokyo, having all the official stuff sorted early means fewer headaches later. Here’s a handy guide to help you get everything in order.

Main Documents You Might Need When Travelling with Kids

First things first—every child needs their own passport, even tiny babies. UK child passports last five years, but lots of countries want them to be valid for at least six months after you come back, so always check the dates. Some places also ask for visas. The USA, for example, needs an ESTA for every traveller—including the little ones. Countries like India have their own rules and forms to fill in. It’s worth checking visa info for your destination as soon as you start planning your trip.

It doesn’t matter if you’re popping over to France or heading all the way to Australia, you need to take compliant photos for the travel documents. The rules are strict: no grins, mouth closed, plain background. And getting photos for passports can be tricky with little ones. Your best bet is automatic software like https://passport-photo-software.com/. Passport Photo Maker helps you instantly turn a regular picture into an ID photo that meets the official standards. There’s a built-in database of specifications for different countries and types of documents, so you can fully rely on this software and stop worrying about submitting the pics. This is not only handy but also cheaper and quicker than going to a booth or studio with your little ones.

If you’re travelling solo with your child or they’re going with a relative, it’s a good idea to have a letter from the other parent saying it’s okay. It should include trip details, contact info, and a copy of the non-travelling parent’s passport.

A birth certificate (the full version showing both parents) can be really useful, especially if you and your child have different surnames. It just helps avoid awkward questions at the border. And don’t forget travel insurance. Make sure your policy includes cover for children and anything specific they might need, like medical cover. Some countries might also ask for proof of certain vaccinations or a negative COVID test.

Different Requirements: EU, USA, Asia, and Beyond

Since Brexit, heading to the EU means following new rules. Your child’s passport has to be less than ten years old and valid for at least three months after your return. You don’t need a visa for short trips under 90 days, but definitely check your passport dates.

Going to the States? Every child needs their own ESTA and their passport has to be one of the chip-enabled ones. The form is quick to fill out online, but don’t leave it to the last minute.

Travelling in Asia is a mixed bag. Japan and South Korea are more relaxed and don’t ask for visas for short visits, but India and China are stricter. 

If you’re heading to Australia or New Zealand, you’ll need to apply online for an ETA or NZeTA. African countries like Kenya ask for e-visas and sometimes health records. In South America, places like Brazil might ask for parental permission letters even when both parents are there.

Things change often, so always double-check the latest rules on official government or embassy websites.

How to Get or Renew Children’s Documents Quickly

You can apply for a child’s passport online through the GOV.UK site. As of 2025, it’s £70. It usually takes up to 10 weeks, so don’t leave it too close to your travel date. Need it fast? You can pay extra for the one-week Fast Track option. As for visas, they vary a lot. Some are super quick and easy (like the ESTA for the USA or Australia’s ETA), but others—like China’s—can be a bit of a process and take a while. It’s better to get started as soon as you can.

Safety & Organisation Tips

  • Give them a card or wristband with their name, your contact number, and the hotel name. It’s a small thing but gives real peace of mind.
  • If your child has medical issues, pack any medicine in your carry-on with a doctor’s note. Keep it all labelled and handy.
  • Airport security can be a bit of a mission. You’re allowed to bring baby milk or medicine through, but you’ll need to show it. Having everything ready in a clear bag makes it easier.
  • Delays are part of travel life, especially with kids. Pack snacks, toys, colouring books—anything to keep them entertained. Always carry spare clothes, wipes, and nappies if needed.
  • Don’t try to pack too much into each day. Kids tire out quickly, so leave time for breaks and naps. A chilled-out plan makes for a much happier trip.

Practical Tips for Organising Documents

Keeping everything together makes life so much easier. Grab a folder or wallet with different pockets and keep all your documents neat and tidy—passports, birth certs, insurance papers, tickets, etc.

Make a few paper copies of the key stuff and stash them in a different bag, just in case. You can also scan everything and store it securely online with apps like Dropbox or Google Drive. It’s a lifesaver if something goes missing.

Label everything clearly—pop your child’s name and passport number on the back of each copy so you’re not digging around for the right one in a rush.

Summing Up

Travelling with kids doesn’t need to be stressful. A bit of prep and the right documents make all the difference. Start early, get everything sorted, and give yourself some breathing room. That way, you can focus on making fond memories—not panicking about paperwork. Before you begin the journey, tick off the essentials: 

  • photos for your travel documents, 
  • your child’s passport,
  • consent letters, 
  • birth certificates, 
  • insurance documents, 
  • health info, 
  • spare copies, 
  • emergency contacts, 
  • something to keep your child busy. 

Once it’s all done, you can breathe easy and start getting excited about the upcoming adventures!
