Traveling while breastfeeding - aka pumping in an airport bathroom

I've had to take a few trips for work since the babies were born. This is tough, for two reasons: (1) pumping and traveling with breast milk, and (2) ensuring care for babies while I'm away. I have gotten completely comfortable with caring for both babies on my own - dr. appts, overnights, etc. Is it tough? Yes. Is it doable? Definitely. Kudos to single moms of twins, though - I'm certainly glad I don't have to do it all the time. Although DH has become more comfortable with caring for the girls on his own, so far the overnight care has been pretty daunting for him, so my mom usually comes to help out. Luckily my work trips are usually somewhat flexible so I have been able to plan around DH's schedule and my mom's schedule.

 My trips have been for one overnight, two full days - I'm not comfortable with anything longer than that yet, and I think the amount of milk I would have to bring back for anything longer would be prohibitive - a two-full day trip is 100oz plus pumping and dumping some... 

 For the few days prior to my trip, I don't freeze any milk, and instead store it in the fridge in 8oz Evenflo bottles, numbered 1-9 or 10 so DH can easily tell which is the oldest and should be used first. This allows him to prep bottles with the least amount of hassle, and he can always give an additional ounce or two without having to defrost extra. This was especially helpful for the first trip where I wasn't sure what the girls would drink in their "at home" bottles. (SB in particular goes on a bit of a nursing strike when I'm gone). Here is my packing list for pumping while traveling: 

 -handsfree bra 

 -medela pump - "pump" only, plus wall adapter and battery adapter 

-nursing cover (in case you have to, in a pinch, pump in public) 

-medela cleaning wipes 

-zip lock bags (for storing pump parts in between pumping sessions) 

-large hardside cooler. I think this keeps things colder than a softside, but it may be more difficult to stow under your seat on the plane - I use one that still has a canvas exterior and shoulder strap so I can carry all the other items for pumping. My pump and pump parts fit in the main section of the cooler. 

-12 8 oz evenflo bottles These don't have screw on caps, but I use the medela ones - I have almost 12, and I use the inverted nipple/cap combo on the few remaining. You can buy extra caps, I believe, but I haven't searched to hard for them since I don't need them often. 

-ice packs 

-pump parts - one full set. I usually plan out my pumping so that I can pump and combine bottles and use every bottle for storage. I don't combine cold and freshly pumped milk, as I believe this is a no no, so this sometimes takes some coordination. 

-dish soap to wash parts at the hotel 

-2 80 mL snap-lid containers 

-8 AA batteries 

 -hand sanitizer 

 My trips have, for the most part, gone off without a hitch. A few things I've learned: (1) Nursing/pumping will allow you to travel with breastmilk in excess of the 3 oz rule. You also can bring items greater than 3oz if they are frozen solid when you pass through security. They will test a random number of bottles, depending on the volume you are traveling with - they no longer open the bottles or use the paper strips. 

(2) The TSA website says you should tell them a TSA agent if you are traveling with breastmilk. Even if you do, they will still run it through the xray without telling anyone else, you will have to tell the person operating the xray that you are traveling with breastmilk, too. 

(3) Make sure you ask for a fridge for your hotel room, and make sure it will be turned on and cold prior to your arrival. Also make sure that it isn't so cold that it will freeze your breast milk - if you freeze then thaw breast milk, you have to use it in 24 hours. 

(4) airports are surprising unfriendly for pumping. If you can find a family restroom, use that. Otherwise, sometimes the handicapped stall may be your best bet, or a quiet corner under a nursing cover. 

 (5) Don't be afraid to inquire about time and a place to pump at your destination.

(6) people will be very curious why you are traveling with a large cooler. 

(7) plan to nurse as soon as you get home if possible - even if it's a dreamfeed.
