Traveling with kids goes more smoothly when you pack for each age group’s real needs. This guide covers the essentials for babies, toddlers, and school-age kids, along with the TSA and safety rules that matter most. For a general overview, see the kids travel essentials guide, and use the family travel tips for broader planning.
Plan before you pack
Before sorting the carry-on, check the official rules that apply to your trip. The TSA liquids rule explains what can go in carry-on bags, including formula, breast milk, and medically necessary liquids. The TSA What Can I Bring page covers item limits and current screening procedures, including the fact that most travelers no longer need to remove shoes at standard checkpoints. The TSA REAL ID page explains the identification requirement for domestic flights, which went into effect on May 7, 2025.
Safety rules matter too. Spare lithium batteries and power banks must go in carry-on bags, not checked bags, as noted in the FAA PackSafe lithium batteries guidance. For international travel, review the State Department traveler’s checklist and consider enrolling in the Smart Traveler Enrollment Program (STEP). Always check the official source and your airline before departure, since rules can change.
Babies: feeding, diapering, and carrying
For babies, the core items are diapers, wipes, a changing surface, feeding supplies, and a way to carry the baby hands-free. Pack enough diapers and wipes to cover the full travel day, plus a few extra in case of delays. A portable changing pad and a resealable bag for dirty diapers keep you prepared without taking up much space.
Formula and breast milk are allowed in reasonable quantities through airport security, but they must be screened separately. Keep them easily accessible and be ready to tell the officer what they are. As noted in the planning section, the TSA liquids rule is the official reference, so check it before your flight.
Feeding gear includes bottles, nipples, a container of formula powder or prepared bottles, and, if you use breast milk, an insulated bottle bag and ice pack. Check the formula manufacturer’s instructions for mixing and storage, and keep prepared milk cool. If you pump, think about whether you need to bring the pump and how you will clean it on the road.
A soft carrier is useful for moving through the terminal and letting your baby nap. Follow the carrier manufacturer’s instructions for your baby’s weight and positioning, and remember that you will need to remove bulky items when going through screening.
Before the trip, ask your pediatrician about any vaccines, fever medicine, or motion-sickness relief your baby might need. Carry medications in their original packaging, and ask your doctor or pharmacist about the right dose for your child’s age and weight. Do not give a dose without their direction.
Toddlers: snacks, comfort, and potty supplies
Toddlers eat often, attach to specific objects, and may not have reliable bathroom habits. Pack snacks that are easy to open and unlikely to spill; crackers, cereal, fruit pouches, and cheese options work well. Keep snacks at the top of the bag and offer them one at a time so a full bag does not disappear in the first hour.
For drinks, pack an empty spill-proof cup or bottle and fill it after you pass security. A spill-proof cup is helpful for bumpy roads and airplane trays, but the cup must be empty during screening unless it contains formula, breast milk, or a medically necessary liquid.
A small stuffed animal, blanket, or pacifier can make a strange place feel safer. Bring a backup if your toddler has a favorite that is small and easy to lose. If your toddler uses a pacifier, pack one or two extras in an easy-to-reach pocket.
If your toddler is potty training, bring disposable changing pads, wipes, and an extra set of underwear and pants. For longer trips, a small portable potty seat or urinal can be helpful, but check the manufacturer’s instructions and your airline’s carry-on policy before you pack it. Wet wipes and resealable bags are useful for messes at any age.
Small toys, sticker books, and washable crayons can keep a toddler occupied during stops and delays. For flight-specific advice, see the flying with a toddler essentials guide.
School-age kids: their own bag and offline activities
School-age kids are old enough to carry their own backpack, and letting them pack it helps them feel responsible for their gear. Keep the bag light, and keep the airline’s carry-on size limits in mind. A standard school backpack often fits, but check your airline’s current measurement guidance before travel.
Fill the pack with things your child can use alone: a book, a notepad, pencils, and offline activities like cards, crossword puzzles, or coloring pages. If your child takes an electronic device, include the charging cable and a power bank. Spare power banks and lithium batteries must be in carry-on, not checked, so keep them in this bag.
For listening to a movie or music, volume-limiting kids headphones help protect hearing. Choose a pair designed for children, and follow the manufacturer’s instructions for safe listening volume and fit. Pack the headphones in the child’s own backpack so they are easy to find.
Clothing layers and health supplies
Temperatures change inside airplanes, rental cars, and airport terminals, so layers are easier to manage than one heavy coat. For babies, pack an extra onesie, a sleep sack or swaddle if you use one, and a soft hat. For toddlers, include long pants, a hoodie or sweatshirt, and a rain jacket or waterproof pants if rain is likely. School-age kids can choose their own favorite hoodie and bring an extra pair of socks. Always pack at least one full change of clothes per child, and put it in the carry-on rather than checked luggage.
The health kit should include hand sanitizer, tissues, small bandages, and any daily medication your child takes. For fever or allergy medicine, ask the pediatrician or pharmacist about the right product and dose for your child’s age and weight. The CDC Pack Smart travel health kit page has a useful list of basic supplies for family trips. Declare any medically necessary liquids during screening, and remember that your child’s comfort is as important as the gear itself.
A quick-reference table
The table below summarizes the age-by-age essentials for a travel day. Use it as a final checklist before you leave.
| Age group | Travel day must-haves | Good to have on hand |
|---|---|---|
| Babies | Diapers, wipes, changing pad, formula or breast milk in reasonable quantities, feeding bottles, carrier | Extra onesie, blanket, hat, small first aid supplies |
| Toddlers | Snacks, spill-proof cup, comfort item, potty supplies, change of clothes | Small toys, sticker book, pacifier extras, wipes |
| School-age kids | Own backpack, headphones, book or notepad, offline activities | Hoodie, charger, power bank in carry-on, hand sanitizer |
What you can skip
It is easy to overpack for kids, but a lighter bag makes the day easier. You can skip toys that make noise or need constant adult help. You can also skip anything that only works with a specific outlet or battery if you are not sure it will pass screening. For infants, a second changing pad is usually unnecessary; one pad and a lightweight blanket are enough. For toddlers, a bulky potty chair is usually not worth the space; a small folded changing pad and a disposable bag work fine. For school-age kids, skip unnecessary electronics; one charger and an offline activity make the trip smoother.
If a child safety seat is not needed at your destination, leaving it at home reduces heavy baggage. When you do use a car seat or booster, follow the child-restraint law in the state or country you are visiting, and follow the instructions from the car seat and vehicle manufacturers. For local car travel, review the Ready.gov car safety guidance before you drive.
FAQ
Can I bring formula or breast milk through airport security?
Yes. The TSA allows formula and breast milk in reasonable quantities through security, but they must be screened separately from the rest of your carry-on. Pack them so you can pull them out quickly, and check the current TSA liquids rule before your flight.
What should I do about my child’s medication when traveling?
Carry medications in their original packaging and keep the label visible. If your child needs a liquid medication, tell the security officer before screening. Ask your pediatrician or pharmacist about correct dosing and any travel-specific vaccine needs before you leave.
Does my child need a separate passport for international travel?
Generally, every child needs a passport for international travel, regardless of age. Check the State Department traveler’s checklist and confirm requirements with the embassy or consulate of the country you are visiting before booking.
Can I use a child safety seat on an airplane?
In most cases yes, but the seat must be approved for aircraft use and fit within the airplane seat. Check the seat label for FAA or equivalent approval, and contact the airline to confirm its policy. For car travel, follow the laws in each state and the car seat manufacturer’s instructions.
Packing for kids gets easier when you start with age-specific needs and work backward. Keep the focus on feeding, sleeping, comfort, and entertainment, and always review the current official rules for security, batteries, and international travel. With this list in hand, you and your children will be ready for the trip.
