Airport Security with Children: US vs EU Rules

<p>Airport security with children isn't the same everywhere. The US has its own child screening rules, the EU sets a framework, and individual airports are changing what they allow. This guide compares what official sources say on liquids, baby food, strollers and shoes, so you can check your own route.</p>

Last reviewed: November 2026. This guide draws on the US Transportation Security Administration (TSA, checked on 24 October 2026), the European Commission’s page on liquids, GOV.UK and Dublin Airport as an example of a European airport with newer rules. Screening officers have the final say at the checkpoint, and rules change. Check each airport on your route before you travel.

You’ve got a pushchair, a nappy bag and a small child who doesn’t want to take off their coat. Security lines are hard enough without wondering whether the rule you remember applies in the airport you’re in. Part of the confusion is that there isn’t one rule. In the US, the TSA sets national rules. In Europe, EU rules set the framework, but airports with newer scanners are changing what they allow. And the UK has its own rules, which can differ between airports. Here’s how they compare, and what you should do for your own trip.

Quick answer

• Baby food and milk: allowed through security in the US, EU and UK, beyond the normal liquid limits. Tell the officer and expect it to be screened.
• Normal liquids: rules vary by airport. The classic rule is 100 ml containers in a clear bag, but some airports allow up to 2 litres.
• Shoes and jackets: the TSA lets children aged 12 and under keep on shoes, light jackets and headwear. Other countries may be different.
• Strollers: the TSA says they go through the X-ray. Check how your airport handles them.
• Staying together: the TSA says children won’t be separated from their parent.
• Your return flight counts. GOV.UK says to check your departure airport, any connecting airports and your return journey.

Decision table: how the rules compare

Why Europe is confusing right now

The European Commission’s page sets out the framework that most travellers know: liquids in individual containers of no more than 100 ml, in one transparent one-litre bag, plus exemptions for liquids used during the trip for medical purposes or special dietary needs, including baby food. It also explains that the restriction was intended to be temporary, until technology to screen liquids became available.

That change is now being felt. Dublin Airport, for example, says that liquids, gels and electronics can stay in your carry-on when going through security, that the previous 100 ml limit no longer applies, and that containers up to 2 litres can be brought through. It also says liquids no longer need to be in clear plastic bags. But that’s one airport. GOV.UK takes a similar line for the UK: most airports still have the 100 ml limit, while some may allow up to 2 litres.

So a route with a connection can involve different rules at each airport. Pack for the strictest airport on your route, and pack your liquids so you can get them out quickly.

Step-by-step: getting through with children

1. Check all airports on your itinerary, including the return and any connection.
2. Pack baby food and milk at the top of your bag. Tell the officer as soon as you reach the belt.
3. Bring only what you need. GOV.UK’s wording is “enough for the journey”. Expect questions if you have much more than that. Our guide to flying with formula, breast milk and pumps has the detail.
4. Dress for it. Slip-on shoes and light layers can help, wherever you are.
5. Empty the pockets of everyone, including children. Dublin Airport asks all passengers to take out keys, wallets and phones.
6. Fold the stroller if you’re asked, and be ready to lift it on to the belt. Remove anything from its pockets.
7. Keep devices charged. GOV.UK says you won’t be allowed to take a device on board if it doesn’t switch on when requested. See our power bank guide.
8. Agree who does what. One adult manages the bags and the other stays with the children. If you’re on your own, see our solo parent’s checklist.
9. Allow time. Bags with milk, medicines or pouches may need to be checked by hand.

Practical points for babies and toddlers

• Liquid-filled teethers and ice packs. The TSA says that these are allowed. Keep them where they can be seen, and check other airports.
• Frozen milk. GOV.UK says that frozen breast milk isn’t allowed in hand luggage. Check before you pack it.
• Baby must be present. GOV.UK’s table says that for formula, cow’s milk, sterilised water, soya milk and baby food in hand luggage, the baby must be travelling with you.
• Medicines. GOV.UK says to check the exemptions for medicines. Keep them in their packaging, and see our first-aid kit guide.
• Water bottles. Empty them unless your airport allows otherwise. Our guide to leakproof bottles explains more.
• ID. The American Academy of Pediatrics says that children don’t need ID at the TSA for US domestic flights, but an airline may ask for proof of age. Dublin Airport says your passport won’t be checked during screening, so pack it away.

What we couldn’t confirm

We couldn’t open current pages for every major European airport, and we haven’t listed rules for airports we couldn’t read. Nor could we confirm a single EU rule on children’s shoes, coats or stroller handling. Treat the table above as a starting point, and look at each airport’s own security page.

Common mistakes and real-world scenarios

• Relying on your outbound experience. A large bottle allowed at one airport may be taken away at the next.
• Going through with a full bottle “for the toddler”. Baby food exemptions are about need. Ask if you’re not sure, and be prepared to explain.
• Not saying anything. Telling the officer early is usually easier than having your bag pulled aside.
• Keeping a child’s favourite toy in the stroller basket. It may have to go through the scanner too, and tears are likely. Prepare your child with a simple story.
• Taking a coat off a sleeping child. It may be simpler to wake them gently earlier, rather than at the belt.
• Surrendering something you need. Dublin Airport says that you may be able to return landside with a restricted item, instead of surrendering it. Other airports may have similar options.
