The Ultimate Packing List for Flying with a Baby, Toddler, or Preschooler

I used to think packing for a flight with a baby was the hard part. Then my baby became a toddler. Then the toddler became a preschooler who "packs himself" and somehow still needs three backup outfits. Here's the truth nobody tells you: the packing list doesn't get shorter as they get older. It just changes shape.

So instead of writing one generic list, I broke this down by stage, because what saved us on a flight with a six-month-old is not what saves us now with a very opinionated four-year-old. If you only read one post on this blog before your next flight, make it this one — it's the closest thing to a cheat sheet I have.

The Non-Negotiables, No Matter the Age

Before we get into stage-specific gear, here's what goes in the bag every single trip, whether we're flying with a baby, a toddler, or a preschooler.

Packing List for Flying With a Baby (0–12 Months)

This stage is all about feeding logistics and keeping them comfortable in a seat that was clearly not designed with babies in mind.

• Inflatable travel nursing pillow — packs completely flat, inflates in under a minute, and gives you real support for feeding at 30,000 feet
• Bottles, formula, or pumping supplies in a labeled, easy-access pouch
• A lightweight swaddle or blanket for temperature swings on the plane
• Pacifiers or something to help with ear pressure during takeoff and landing
• A soft carrier for hands-free walking through the airport

Real Talk From a Newborn Flight

Our first flight with a newborn taught me that the inflatable nursing pillow wasn't just for feeding — it became a makeshift barrier so she wouldn't slide around during turbulence, and later, my own neck support on the red-eye home. One item, three jobs. That's the bar for anything that makes it into our bag now.

Packing List for Flying With a Toddler (1–3 Years)

Toddlers bring a new challenge: energy that has nowhere to go in a 17-inch-wide seat. This is where the seat extender earned its permanent spot in our bag.

• Airplane seat extender — gives them a flat space to stretch out, nap, or sit criss-cross instead of squirming for hours
• A handful of small, new-to-them toys or books (novelty buys a solid 20 minutes each)
• A tablet loaded with downloaded shows, just in case
• Pull-ups or extra diapers, even if you're "basically done" with them
• A reusable, spill-proof snack cup

Packing List for Flying With a Preschooler (3–5 Years)

By this stage, they're more independent — but also more aware of every germy surface, every delay, and every "are we there yet" opportunity.

• Tray table cover, because preschoolers touch everything and then touch their face
• A small backpack they carry themselves (it builds independence and buys you five minutes of pride)
• Sticker books, coloring pages, or a travel journal
• Noise-cancelling headphones sized for little ears
• A "big kid" water bottle they refill after security

My Best Tip Across All Three Stages

Pack like the checked bag might not show up. Every single "must-have" above lives in our carry-on, not our suitcase. If it's the difference between a calm flight and a meltdown, it doesn't leave your side.
