How many outfits should I pack for my kids?

A reliable formula is one outfit per night plus one extra. Toddlers and babies need more because of spills and blowouts, so add one or two extra outfits per day for under-twos. For trips longer than a week, pack for seven days and plan one load of laundry.

What should be in a family carry-on bag?

Pack medicine, travel documents, phone chargers and power banks, snacks, an empty water bottle, a full change of clothes for each child, a spare shirt for each adult, diapers and wipes for little ones, and a small bag of quiet activities. If your checked bag disappears for a day, you should still be fine.

Can I bring baby formula and breast milk through TSA?

Yes. TSA allows formula, breast milk, toddler drinks, and baby food including puree pouches in carry-ons in amounts over 3.4 ounces, and they do not need to fit in your quart-sized bag. Tell the TSA officer at the start of screening that you have them. Check tsa.gov before you fly in case procedures change.

Can I pack a power bank in my checked bag?

No. Spare lithium batteries and power banks must go in your carry-on, not checked luggage. If your carry-on gets checked at the gate, take the power banks out first. Some airlines also limit how many you can bring or whether you can use them during the flight, so check your airline's rules.

What do people forget most when packing for a family trip?

The usual culprits are phone chargers, kids' medicine and a thermometer, swimsuits, the child's sleep comfort item, a night light, sunscreen, and enough socks. Running a written checklist the night before and again at the door catches most of them.

How do you pack for a family so you don't overpack?

Use quantity formulas, pick one color palette so everything mixes, cap shoes at two pairs per person plus any activity shoes, and plan one laundry load per week. Buy bulky consumables like diapers and sunscreen at your destination when you can.

Family Packing List: Every Trip Type and Every Age

Packing for a family is mostly packing for the one kid who will spill grape juice on their only sweatshirt in the first hour. This master list is built so you never start from a blank page: one core list, add-ons by trip type, add-ons by age, and formulas that tell you exactly how many socks to bring.

Want it as a checklist you can tick off? Use the interactive packing list builder. Pick your trip type, nights, and kids’ ages, and it builds a printable list from everything below.

How to use this family packing list

Think of packing in three layers. Each layer stacks on the one before it.

Start with the core list. These are things every family needs on every trip, from a weekend at grandma’s to two weeks abroad.
Add your trip type. Beach, city, camping, snow, theme park, road trip, or flying. Many trips are two types (flying to a beach), so add both.
Add each child’s age list. A baby and a teen need very different things, and the age list is where most “oh no, we forgot” items live.
Run the formulas. Multiply clothing by the number of nights so you pack enough without hauling a second suitcase.
Pack the carry-on kit last, pulling the most important items out of the main bags.

Do the list two or three days before you leave, not the night before. That gives you time to buy the missing sunscreen and wash the favorite pajamas.

Packing quantity formulas for kids and adults

These formulas assume you will not do laundry. For trips longer than seven nights, pack for seven and plan one load. Most vacation rentals have a washer, and many hotels have a guest laundry room.

Item	Formula	Notes
Outfits (tops + bottoms)	Nights + 1	Bottoms can be nights ÷ 2 for kids over 5; tops get dirtier
Underwear	Nights + 2	Potty-training kids: nights × 2
Socks	Nights + 2	Add 2 pairs for snow, hiking, or rain
Pajamas	1 per 3 nights, minimum 2	Under-3s: 1 per 2 nights
Shoes	2 pairs + activity shoes	Activity shoes = water shoes, snow boots, hiking shoes
Warm layer	1 per person, + 1 for under-5s	A fleece or hoodie works for almost every climate
Swimsuits	2 per person if swimming daily	Wet suits do not dry overnight in humid places
Diapers	(Daily diapers × days) + 10	Or bring 2 days’ worth and buy the rest there
Wipes	1 pack per 3 days	Useful for everyone, not just babies
Extra outfits, under-2s	+1 to 2 per day	Blowouts and spit-up do not care about your itinerary

A simple trick: pack each child’s outfits as complete sets rolled together or in a labeled packing cube. Kids can grab “Tuesday” without unpacking the whole suitcase, and you can see at a glance if you are short.

The core family packing list (every trip)

This list covers every trip type. Copy it once and reuse it forever.

Documents and money

Photo ID for adults, plus passports or other documents for any border crossing
Insurance cards (health, car, travel insurance details)
Reservation confirmations, saved offline on your phone
A credit card and a backup card kept in a different bag
A small amount of cash for tips, parking, and places that don’t take cards

For domestic US flights, TSA says children under 18 traveling with an adult do not need ID, but airlines can have their own rules for minors. For international trips, see our guide to passports for kids.

Health and first aid

Prescription medicines in original containers, plus a few extra days’ worth
Kids’ pain and fever reducer (in the right formulation for each child’s age) and a measuring syringe
Thermometer
Adhesive bandages, antiseptic wipes, tweezers, blister pads
Antihistamine, after checking dosing with your pediatrician
Sunscreen, lip balm with SPF, and insect repellent
Hand sanitizer, tissues, and a few zip-top bags for wet or gross things

Clothing and personal items

Clothes per the formulas above
Toothbrushes, toothpaste, hairbrush, hair ties
Glasses, contacts, retainers, and their cases
One laundry bag or large trash bag for dirty clothes

Tech and comfort

Phone chargers and a power bank (power banks ride in the carry-on, see below)
Headphones for each kid who uses a device, with a splitter if they share
A night light or a small battery lantern for unfamiliar rooms
Each child’s sleep comfort item (lovey, blanket, pillowcase from home)
Reusable water bottles, filled after security

Packing list add-ons by trip type

Add the column for every trip type that applies. A Florida trip with a cruise and a day at a theme park gets three columns.

Trip type	Add these	Often forgotten
Beach	Swimsuits ×2, rash guards, sun hats, beach towels (if not provided), sand toys, water shoes, cover-ups	Reef-safe sunscreen if required locally, baby powder for sand removal
City	Comfortable walking shoes, compact stroller or carrier, small daypack, transit card app	One “nicer” outfit, a rain jacket
Camping	Tent, sleeping bags and pads, headlamps, camp stove, cooler, layers	Extra batteries, a tarp, a spare pair of dry socks per person
Ski / snow	Waterproof jacket and pants, base layers (no cotton), wool socks, gloves plus a spare pair, helmets, goggles, neck gaiter	Hand warmers, lip balm, sunscreen (snow reflects sun)
Theme park	Refillable water bottles, ponchos, portable fan, small backpack, stroller, phone battery	Moleskin for blisters, a sharpie to write your number on young kids’ arms
Road trip	Car seats, car trash bag, paper towels, snacks, motion sickness bags, sunshades	A change of clothes in the car, not the trunk
Flying	Carry-on kit (below), car seat or travel harness if using one, empty water bottles	Gum or a bottle for takeoff and landing ear pressure

Beach

Pack two swimsuits per person if you’ll swim every day. In humid places, a suit worn at 4 p.m. is still damp at 9 a.m. A long-sleeve rash guard means less sunscreen to apply to a wriggling child, which is a gift to everyone. For more on dealing with sand, sun, and tired kids, the family trip finder has beach destinations with their own tips.

City

The city list is light on gear and heavy on footwear. Pick shoes that have already been broken in, and pack a lightweight stroller even for 4-year-olds who “don’t need one anymore.” Cities involve more walking than kids expect.

Camping

Camping has its own long gear list, from tents to stove fuel. Use the full checklist in our first family camping trip guide, which also covers how to stay warm at night.

Ski and snow

Avoid cotton for base layers, since it stays wet and cold. Bring two pairs of gloves per child. One pair will be soaked by lunch, and swapping in dry gloves buys you another hour on the hill.

Theme parks

Small, light, and waterproof is the goal. A poncho folds smaller than an umbrella and keeps hands free for holding little ones. Check the park’s list of allowed items (stroller sizes, coolers, and wagons vary) on its official website before packing.

Road trips

Keep a “car bag” within reach: snacks, wipes, paper towels, a trash bag, a change of clothes for each kid, and motion sickness bags. If you’re planning a long drive, our road trip with kids guide covers stop cadence, car setup, and sleep.

Packing list add-ons by age

Age	Must-haves	Nice to have
Baby (0–12 mo)	Diapers, wipes, changing pad, formula or pump supplies, bottles, bottle brush, burp cloths, baby carrier, portable crib or play yard if not provided, car seat	White noise app or machine, blackout cling film for windows
Toddler (1–3)	Diapers or training pants, snack cup, sippy cup, stroller, portable potty seat, plenty of spare clothes, safety outlet covers	Toddler-size utensils, a new small toy saved for the trip
Big kid (4–10)	Booster or car seat as required by law and fit, small backpack they carry themselves, activity kit, refillable water bottle	Kid camera, journal, travel games
Teen (11–17)	Their own chargers and headphones, toiletries, ID if they have one, a little spending money	Let them pack their own bag, then check it against the list

Babies

Babies need the most stuff and care the least about the destination. Ask your lodging whether they provide a crib or play yard; if they don’t, bring one. The AAP’s safe sleep guidance is that car seats and strollers are not a safe place for routine sleep, so a flat, firm sleep space matters. Car seats should stay rear-facing as long as your seat’s height and weight limits allow, per HealthyChildren.org. Our guide to traveling with car seats covers flying with one.

Toddlers

Toddlers are where spare clothes earn their keep. Pack outfits as nights plus two, and keep one full outfit in your day bag. A wrapped new toy or sticker book, handed over at the worst possible moment, is worth more than three old toys.

Big kids

Kids from about 5 up can carry their own small backpack with a water bottle, a snack, a book, and a jacket. Let them pick some of their clothes from a pre-approved pile, which cuts down on “I hate this shirt” on day three.

Teens

Give teens the core list and their age list and let them pack. Then do a quick check for the essentials they skip: socks, a warm layer, and their own phone charger, so they aren’t borrowing yours.

The family carry-on kit

Whether you fly, drive, or take a train, assume your main bag will be out of reach for 24 hours. This kit keeps you comfortable until it shows up.

Medicine and documents. Never check prescriptions, passports, or IDs.
A full change of clothes for each child and a spare shirt for each adult.
Chargers and power banks. Spare lithium batteries and power banks go in your carry-on, not your checked bag. If your carry-on is gate-checked, pull them out first. Some airlines set their own limits on using them in flight.
Snacks, more than you think. Pack a mix of protein, crunchy, and one treat.
Empty water bottles to fill after security.
Diapers and wipes for one day plus a few extra, if you have little ones.
Quiet activities: a tablet with downloaded shows, headphones, a sticker book, a small notebook and crayons.
Comfort item and a light blanket for napping.

TSA rules for liquids, formula, and baby food

The TSA liquids rule limits most liquids, gels, creams, and pastes to containers of 3.4 ounces (100 ml) or less, packed in a quart-sized bag. Medicines and infant and child nourishments are exempt.

According to TSA’s page on traveling with children, formula, breast milk, toddler drinks, and baby food (including puree pouches) are allowed in amounts over 3.4 ounces, and they don’t need to fit in the quart bag. Tell the officer at the start of screening. Ice packs and gel packs to keep them cold are also allowed. Strollers, car seats, and baby carriers go through the X-ray, so fold the stroller while you wait in line. TSA rules can change, so check the site the week you fly.

Packing mistakes families make (and the fix)

Mistake	Fix
Packing a “just in case” outfit for every scenario	Use the formulas, pick one color palette, and plan one laundry load
Kids’ medicine in the checked bag	Medicine always lives in the carry-on
Forgetting the sleep comfort item	Put it on the list as item one for each child, and pack it last
Too many shoes	Two pairs plus activity shoes, and wear the bulkiest pair on travel day
Bringing a week of diapers	Pack two days’ worth and buy the rest at your destination
No plan for dirty clothes	One laundry bag per family, or a large trash bag

The cheapest substitution on this whole list: a stack of gallon zip-top bags. They hold wet swimsuits, leaky shampoo, a car-sick child’s clothes, and a half-eaten sandwich, and they weigh nothing.

Wrap-up: build your list now

Pick your trip type and your kids’ ages, run the formulas, and pull the carry-on kit together first.
