Flying with a baby? It’s an adventure—one that requires strategy, patience, and a well-packed bag.

I’m a mom of a baby under one year old, and I travel frequently for both work and personal reasons. These days, my little one occasionally tags along on my trips. He’s already been on a few cross-country flights as my lap infant, and while I’m still fine-tuning my packing strategy, I’ve developed a system that works well so far.

Checked Bags vs. Carry-On: Should I Check a Bag When Flying with a Baby?

Before having a baby, I was firmly in the no-checked-bag camp—I wanted to get out of the airport as quickly as possible. But traveling with a baby? That rule had to go. Since I already have to gate-check his stroller and car seat, I might as well check everything else as well, keeping only what I absolutely need on the plane.

Choosing the Right Bags: Best Diaper Bag for Flying with a Baby

I discovered that the bags that I already use for everyday carry transition perfectly into a baby's use case. Here is my set-up:

Synik 26 as the diaper bag

Side Kick as my personal bag

At 5’5”, I find that the Synik 26 is my favorite sized Synik. Its five exterior pockets provide quick access to diapers and milk—which is key. When my baby is hungry, he fusses fast. The last thing I want is to dig through a deep bag or wrestle with zippers to get to his milk. Same goes for diapers—easy access is everything.

Packing Priorities: What to Pack for a Flight with a Baby (Diaper Bag Essentials)

When packing for a baby, my priority isn’t packing light—it’s being prepared. Because something will go wrong.

Flight delay? Extra milk and diapers.

Diaper blowout on the plane? Spare outfit.

Unexpected turbulence + spit-up? Another extra outfit.

Fussy baby? Snacks, toys, and anything that keeps him entertained.
