The Art of Packing Light(ish): Flying with a Baby
When our baby boy was between four and five months old, we embarked on our first major trip involving both a flight and a long car ride. To say it was "an experience" is an understatement! Leading up to the trip, I researched endlessly. Some of the tips I found worked beautifully, while others completely fell flat.
To give you some context, we have a big baby—he’s consistently in the 99th percentile for growth. If you have a big baby, you know exactly what I mean; just carrying him around the house is a full-body workout!
As a first-time mom, I naturally overpacked some things and completely forgot others. This thoughts-and-travel guide is designed to help you streamline your packing list, try a few new tricks, and give you some peace of mind. Because let's face it: if you’re a parent simply attempting to leave the house, you’re already winning.
My goal with Breeze and Bloom is always to keep things as minimalist and intentional as possible—though when traveling with an infant, "minimalist" is definitely a relative term!

Before You Fly: Essential Airline Policies
Before you even head to the airport, it is crucial to research your specific airline’s infant policies. You’ll want to check which documents are required, which car seats are FAA-approved, and what baby gear bags fly for free.
For our domestic flight, we decided to book an extra seat for our baby so we could use his infant car seat on board. We flew JetBlue, and their policy states that for safety reasons, a baby car seat must be placed in a window seat. Nothing flagged this for us when we purchased the tickets online, and the flight attendant kindly let us know after we had already fastened the seat into the middle row. Keep this structural detail in mind when selecting your seats!
In our experience, bringing the car seat on board was a lifesaver. Our baby boy slept for most of the trip. I think the familiarity of his car seat combined with the white noise of the plane made it feel just like a long car ride.
To make your planning easier, here are the official infant and child travel policies for major airlines:
1. The Ultimate Diaper Bag Packing List
Most airlines allow a diaper bag as an extra personal item that does not count toward your carry-on allowance (but always double-check your airline's specific rules).
Here is exactly what I pack for the diaper bag, keeping a 4-hour flight in mind:
Diapers: I packed 4 for our short flight. Because our baby slept through the flight, we didn't have to change him on the plane; we just changed him right before boarding and immediately upon landing. If you are planning a long-haul flight, pack at least 5 to 6 clean diapers in your bag.
Wipes: Two travel packs (around 10–20 wipes each).
Diaper Rash Cream / Ointment.
Disposable Changing Pads: Airport changing tables can be unpredictable. I use disposable pee pads to cover the surface before laying down my portable changing pad. I pack 3 or 4 for short flights and 5+ for longer trips.
Baby Rags / Burp Cloths: At least 2.
Bibs: At least 2.
A Change of Clothes (Layers are Key): It was cold when we flew, so my boy started the day in a fleece pajama set. Inside the plane, it got warm, so I had to switch him into a light cotton pajama set with a short-sleeve onesie underneath. I recommend packing at least two sets of cotton pajamas, two short-sleeve onesies, two pairs of socks, and a beanie.
Swaddle Blanket: Great for blocking out bright cabin lights when they are trying to sleep.
Pacifier & Teether Toy: If your baby uses them.
Toy Secure Strap & Toy Wipes: To keep things from falling onto the dirty airport floor.
Sanitizing Wipes: High-alcohol wipes for your hands when you can't easily reach a sink.
The Mini First-Aid Kit
Keep these absolute essentials inside your diaper bag so they are always within arm's reach:
Infant Tylenol (Acetaminophen)
Baby Thermometer
Infant Vitamins (if applicable)
Baby Saline Nasal
Waterproof Adhesive Bandages
What Didn't Work: The Noise-Canceling Headset
I bought a pair of infant muffle-sound headsets, and my baby absolutely hated them. Coincidentally, a younger baby sitting in front of us had the exact same pair and hated them just as much!
Many products claim these are necessary to prevent ear pain during takeoff and landing. A popular tip is to nurse your baby during these times, but because our flight was delayed, our feeding schedule got thrown off, and nursing wasn't an option. Instead, our baby simply sucked on his thumb, and his ears cleared perfectly. If your baby uses a pacifier, that will work beautifully too. Skip the over-engineering on this one!
2. Pumping and Traveling with Breast Milk
I am breastfeeding, which meant I needed to travel with my expressed milk. During the TSA security check, your milk will need to be tested. It’s a standard protocol, and you can absolutely ask the TSA agent to put on a fresh pair of clean gloves before handling your items. In my case, they simply had me open the bottles and used a test strip over the vapor to check it. It was a smooth process, but mentally preparing yourself and your travel partner for this extra step makes a big difference.
For a comprehensive guide, I highly recommend checking out this TSA Tips & Tricks Guide for Flying with Breast Milk.
My Breast Milk Carry-On Essentials:
Portable breast pump
Insulated milk cooler bag
Portable milk warmer
Clean bottles (enough for every anticipated feeding during travel)
Pump and bottle sanitizing wipes
Power Bank: To ensure your electronic pump stays fully charged.
Extra Swaddle: For privacy or coverage while setting up or removing your pump.
Ziploc Bags: To store used bottles and ensure nothing leaks into your main bag.
3. Main Luggage: Cleaning, Bathing, and Wardrobe
Whether you are checking a bag or utilizing a carry-on, these are the main lifestyle and care essentials you shouldn't leave behind.
Cleaning & Sterilizing
If your accommodations have a microwave and a sink, pack a microwave sterilizer bag, a travel bottle brush set, and a small container of baby-safe dish soap. If you don't have access to a kitchen or microwave, rely heavily on specialized baby bottle cleansing wipes for the duration of the short trip.
The Hotel Bath Routine (Lessons Learned!)
Bath time on our trip did not go smoothly (cue the nervous laughter). I brought an inflatable bathtub and a travel-sized baby wash, but it turned out to be a disaster. First, the inflatable tub was way too small for my 99th-percentile boy. Second, I placed it directly on the shower floor, and the cold tiles caused the bathwater to cool down rapidly.
Tip: If you use an inflatable tub, always place a thick towel or mat between the bottom of the tub and the cold floor.
Most importantly, do not forget your bath thermometer. I forgot mine, and because I couldn't accurately gauge the temperature, my boy cried through the entire bath (and honestly, so did I). My back also severely suffered from bending over the low floor!
Better Bath Packing List: Bath thermometer, a appropriately-sized portable baby tub, baby towel, washcloths, and his usual baby soap from home poured into travel bottles.
The Damp Cloth Trick: I recently learned that using a warm, damp cloth to wash a baby’s head—instead of pouring cups of water—is much less startling for them and saves you from needing to pack a rinsing pitcher.
Wardrobe Organization
The absolute best way to pack baby clothes is to put complete outfits into individual Ziploc bags. This makes getting the baby dressed incredibly efficient. If you need help, you can simply tell your partner to "grab a bag from the suitcase," and everything they need is right there.
The Clothing Checklist:
Onesies and pajamas (Fleece for cold weather, cotton for mild weather, rompers for summer)
Short-sleeve and long-sleeve onesies (for layering)
Coordinating pants and jacket sets
Socks
The Right Hat: Whether it’s a summer sun hat or a winter beanie, choose one with a chin strap. Regular hats slip off a baby's head constantly.
Stroller & Sleep Essentials
Stroller Accessories: Mosquito repellent for babies or a net cover, and a rain cover.
The Play Mat Alternative: I packed a lightweight, waterproof splash mat instead of a traditional play mat because it takes up zero bulk in the suitcase.
Entertainment: A couple of small books and suction-cup spinning toys (they are the absolute best for airplane windows or hotel surfaces).
Baby Carrier: Keep this in your stroller for hands-free navigating through the airport, and wear during the boarding/landing.
Sleep Gear: A Pack 'n Play, a portable white noise machine with a built-in nightlight, a travel mattress pad with fitted sheets, and a familiar sleep sack.
Extra diapers and wipes.
(Note: If your baby is over 6 months old, don't forget to pack solid-feeding essentials like baby spoons, silicone bibs, and a suction plate. I often use our travel stroller as a makeshift high chair!)
It’s a comprehensive list, and finding the balance between packing light and being prepared is always a challenge. Personally, I prefer to over-prepare and overpack for peace of mind. I hope our trial-and-error helps inspire your next family adventure!
