17 Helpful Items for a Working Mom's Pumping Bag

The idea of returning to work after maternity leave can be daunting. Because it’s not really going back to the world you once knew. You have morphed into a new person. You have new values, new needs, and new roles. Going back is like starting a fresh job, but perhaps more intimidating because unlike ever before, you are the person you’re getting to know.

Figuring out my rhythm for pumping at the office took some practice. The employer has a big role to play, but you can also set yourself up for an easier transition back.

Being prepared for various scenarios (a spill, a forgotten accessory) will lift a tremendous weight off your shoulders. So today, I’m giving you a peek into my fool-proof pumping bag.

  1. Breast pump (duh!)
    This might sound basic, but your pump is probably more than just the machine that initially comes to mind. It’s also all the parts. I actually forgot the breast shields on my first day back to the office. Luckily I had a Medela at the time, which is super common. I was able to run to Walmart and get replacement parts in a matter of minutes. From that day forward, I found an easier way to do my “pump part checklist.” Rather than looking for tubes, membranes, shields, bottles, cords, etc., I started counting the parts. I had 15 pieces I needed to bring with me. If my count was off, I’d take a deeper look to see what I might be missing. I now prefer a Willow Pump, which only has six pieces. Woohoo! And here’s a pro-tip: Between pumping sessions, I'd keep the parts that touch milk in gallon sized Ziplock bag and throw it in the fridge when not using it. This way I didn't have to wash parts more than once a day, or worry about potential dangers of using the sink at work.

    Willow breastmilk storage bags
  2. Milk storage bags
    If you're using disposal bags, it’s easy to unintentionally run out. In a pinch, plastic storage bags (like Ziplock), are sanitary and will do for some breast pumps. The Willow I used required custom bags and I learned to always keep two packs of them with me. The second bag read “REFILL” prominently in black Sharpie. That was my cue to add a new supply when I got home, or hop on Amazon for a replacement pack. Note that the Willow now offers reusable milk containers.

    Junobie Bags

    If your pump doesn't require a special bag style, then I highly recommend choosing a sustainable option. Junobie created eco-friendly and reusable breastmilk storage bags made of food-grade silicone. You'll save money in the long run, do good for the planet, and they're just beautiful!

    Medela wipes

  3. Pump wipes
    These are made to safely disinfect pump parts (Amazon, $7), without using chemicals that are too strong. Truthfully, I rarely use these, but I’m always grateful to have them when I drop a part on the floor.

    Cottonelle wipes
  4. Paper towels or disinfectant wipes
    Hopefully your employer will have paper towels available, but I’ve definitely been in a pinch before and been grateful to have a small stash handy. Even if you don’t have a spill, you may need to wipe down the surfaces around you.

    Cooler with ice packs
  5. Cooler with ice packs
    You can use any insulated lunch bag, but I recommend one that’s taller, or  is specifically designed for milk storage (Amazon, $15), so you can keep your spoils upright! While you might not cry over spilled milk, you WILL shed tears over wasted breastmilk. Keeping the bags upright minimizes the chance of spilling. And while I used to keep the ice packs in a freezer and load everything up at the end of the day, I’ve since learned to put the milk in the cooler after each pump, along with the ice packs. Then I put the entire cooler in the refrigerator. This might sound unnecessary, but depending on how many people are opening and closing the fridge, it can help ensure your milk stays at a safe temperature.

    Giant Eagle Pecan Pumpkin Pie Hand Sanitizer
  6. Hand sanitizer
    Some pumping rooms have sinks, but not all. Germs can easily spread in the office and it’s so important to keep your milk safe. I love Giant Eagle’s Pecan Pumpkin Pie sanitizer ($1). It smells delicious and is super hydrating.

    Kopari Coconut Oil
  7. Coconut oil
    After our allergy testing ruled out tree nut issues, I switched from lanolin (an animal wax that protects and soothes nipples) to coconut oil. It’s cheaper, vegan, washes out of fabrics more easily, is safe for the baby (assuming you don’t have allergy issues), and can double as hand moisturizer and lip balm in a pinch. In the past I used a kitchen-sized tub, but my friends gifted me a lovely 2.5 oz container, which is perfect for this application. It’s Kopari brand from Sephora. If you’re not buying from a grocery store, just make sure coconut oil is the only ingredient.

    Burt's Bees Hand Cream
  8. Hand cream
    If you’re using lanolin instead of coconut oil like I recommended above, get some heavy moisturizing cream and keep it with you. You wash your hands so much as a mom – with every diaper change, before every feeding, after touching surfaces in public. It doesn’t matter what time of year it is, your hands will inevitably dry out and crack. Try something that doesn’t have alcohol, like Burt’s Bees almond & milk hand cream.

    Water Bottle
  9. Water bottle
    Staying hydrated is always important, but never more so than when you’re pumping! You’ll need about 100 ounces of water a day. Skip the plastic and bring a bottle or cup from home! I’m rarely spotted without my 32-ounce Bubba cup ($15, Amazon).

    Nutrigrain Bar
  10. Healthy snack
    This is especially helpful in the early days. You’ll likely find yourself ravenous during or after each pumping session. So if you’re not accustomed to bringing, or don’t have access to snacks at work – then start packing! I preferred granola bars or nuts because they keep well if they stay in the bag for a while.

    Compact Mirror
  11. Compact mirror
    An ideal lactation room will have a mirror on the wall. But not all do. And there’s nothing worse than stepping into a meeting, blouse buttons missed unbeknown to you. Give yourself a quick once-over before you head to your first meeting.

    Hair Tie
  12. Hair tie
    If you have longer hair, you may find it beneficial to keep it out of your way while you pump. I love the “no crease” style ($10, Amazon), because they don’t mess up my hairstyle if I put it back down after pumping.



    Breastfeeding Spill
    Pro-tip: Avoid solids or materials that will easily show spills
  13. Backup shirt
    If, during your mirror check, you find a spill, you will be so glad to have an extra shirt handy. Because trust – when you have a spill or lanolin stain, it won’t be in a flattering spot. In addition to the extra shirt, I recommend keeping a neutral sweater on the back of your chair. Just in case you’re having a really bad day. It can also be nice on those days the office is cold.

    However, if you want to lighten the load in your pumping bag, our shirts are pumping-friendly to decrease the likelihood of spills, and water-repellent should a mishap occur. Huzzah!

    Medela Micro-Steam Bags
  14. One micro-steam bag
    With these brilliant creations, you simply throw your parts and a little water in a bag, toss the bag in the microwave for 3 minutes, and bam! Your parts are disinfected. So much easier than boiling parts in hot water. Before you give this a try, read the owner’s manual on your pump to ensure it’s safe (but it should be). Truthfully, I’ve only used this once in a year at the office. But it’s reassuring to know it’s available if I need it.

    Meela Breastmilk Storage Guidelines Magnet
  15. Milk storage guidelines magnet
    Okay, so I don’t have this in my bag every day, but it’s a nice thing to have with you on day one. Medela sells a handy magnet that lists out the safe temperatures for milk, how quickly milk needs to be used or stored, and lists out resources for more info. I slapped this on the fridge in the lactation room for me and other moms to reference as needed. These days I feel like I have the temperature ranges and timelines memorized, but in the beginning it can be tough to keep straight.

  16. Fridge thermometer
    Knowing the safe temperature ranges for your breastmilk is useless if you don’t know what the fridge is registering at. The company I worked at when my son was born admittedly used an old fridge for the lactation room. One of the HR reps met with me before my leave and shared she wasn’t sure how reliable it was. So I got a thermometer to keep an eye on things. And sure enough, I noticed the fridge would range from 26 – 42 degrees on any given day. And I was the only one using it, so it wasn’t because the door was open all the time! This is why I highly recommend storing your milk inside of an insulated bag within a fridge. This liquid gold is far too precious to risk spoiling!

  17. The bag itself
    Originally I had ordered a fancy leather Coach diaper bag that I planned on using at work for my pump parts. While beautiful, I found it to be bulky, so I resold it. When I was still using the Medela, I switched to a smaller bag I found on Zulilly. It did the job and came with lots of smaller storage pouches – an insulated cooler, wet bag and wipe bag to name a few. But it screamed diaper bag and felt a little embarrassing to me. Now that I’m using the smaller Willow pump, I’ve been able to downgrade to a simple waterproof tote ($24 on Amazon). It fits everything I need, doesn’t make me feel like a bag lady and definitely doesn’t scream “I’M A NURSING MOM” to those huddled inside a cramped elevator space with me.

    Truth be told, my bag is a little full with all of this in it today. But things like the water bottle, extra shirt, magnet and thermometer can often be left in a desk drawer at the office.


Veteran mamas, what did I leave out? Or did I list anything that you didn’t personally find a need for? Chime in with your feedback!

Remember: There's no need to feel like a bag lady! Lighten the load with Becoming Mama's pumping-friendly shirts. You'll decrease the likelihood of spills with the convenient access, and our water-repellent fabrics will have your back (and front!) should a mishap occur.
