If you find yourself traveling for work while still breastfeeding, take a moment to congratulate yourself. You’re hopefully finding a work/life balance that feels manageable, with a support network in place to help out when you’re away from your baby. There are many milestones to celebrate!

When it comes time to sort out the logistics of your trip, there are a few details to prep that can go a long way in making your journey smoother.

Know your travel rights

First, familiarize yourself with all the things you’re legally protected to do. We’ve pulled together the specifics on your rights flying with your pump.

One handy tip is that in the US, breast milk and gel packs are not only allowed, but don’t need to adhere to the liquid limit of 3.4 or fewer ounces. (You can bookmark the TSA’s page on these items in case you encounter a TSA agent unfamiliar with these rules.)

Pack smart

Pack all your pumping supplies—including a case, charging block and cables, pumping bra, milk bags, gel packs or cooler, a bottle brush, and a mini drying rack or towel—together for easy access. And remember extra water, snacks, and a hand pump for backup.

If you’re flying in the US, you’re allowed to carry these supplies separately in a pumping bag or inside your carry-on bags, because the Food and Drug Administration deems breast pumps medical devices.

Plan where to pump

Research the places you’re visiting to map out clean places where you can pump on whatever schedule you’ve set, and check out state laws for pumping at work.

While pumping in public can bring a range of emotions and challenges, you’re legally protected to do so—in fact, if your state provides better protection than federal law, the state law takes priority.

Keep your milk cold

Think through how you’re going to store your pumped milk if you’re going to be away from your baby—and possibly a refrigerator or freezer—for days. Willow’s Portable Milk Cooler is TSA compliant, holds up to 16 ounces, and will keep your milk at a safe temperature for up to 24 hours.

A few pro tips: Store your milk in serving sizes in a freezer, label each with the date and volume, and don’t let them thaw until they’re ready to use. When freezing milk bags, by the way, you can get all the air out by slowly submerging them in water with the seal just above the surface, then sealing.

Schlep it or ship it

If you have any concerns about storing your milk safely, you can ship it to wherever your baby is, or to wherever you can keep it frozen. Bear in mind that it’s expensive to do, in part because your milk must be shipped quickly and kept cold—and you don’t have to ship your milk at all if you’re pumping primarily to maintain your supply.

It’s legal to ship breast milk in the US (which companies like Milk Stork do), but if you’re exporting it abroad (which DHL and FedEx do), first confirm that it’s legal to send to the destination country.

Set boundaries

Establish and communicate boundaries around how much you’re working on the road, and pay attention to your sleep and stress levels. Your breasts respond to demand, so if you don’t express enough milk when you pump, you might develop supply issues.

And remember: You are your own best advocate! Try to proactively ask your employer for what you need, whether that’s a clean space, a better chair, or more time to pump.

Celebrate the wins

Any amount of breast milk you’re able to provide your baby brings health benefits to both of you, so remember to take time to acknowledge your hard work along the way—especially if you find yourself juggling pumping while traveling for work.
