Returning to work while breastfeeding is one of the most logistically demanding transitions a new mom navigates. The moms who find it manageable are almost always the ones who prepared in advance. Here are eight things worth doing before your first day back, so you are not figuring everything out under pressure while also trying to do your job.
1. Order Your Breast Pump Before Your Leave Ends
If you have not already ordered a pump through insurance, do it well before your return date. Most insurance plans cover a breast pump at little to no cost under the Affordable Care Act, and the process of verifying benefits, getting a prescription, and shipping the pump takes time you do not want to be managing in your final days of leave. Ordering around weeks 28 to 32 of pregnancy or as early as possible during leave gives you time to receive the pump, get familiar with it, and troubleshoot any issues before you actually need to rely on it at work. Browse insurance-covered pump options on Storkpump to get started, or check Medicaid-covered pumps here if you have Medicaid coverage.
2. Confirm Your Flange Size and Get Comfortable with Your Pump Settings
Your first day back at work is not the time to be figuring out your pump settings or discovering your flange does not fit correctly. Spend a few weeks before your return getting to know your pump. Practice a full pumping session using the let-down and expression modes, find the suction level that is comfortable and effective for you, and confirm your flange size. A poor fit is one of the most common reasons working moms struggle to maintain supply after returning to work. Use the Storkpump Flange Sizing Guide to measure and confirm before your first day back.
3. Build at Least a Small Freezer Stash
You do not need a chest freezer full of milk, but having a few days worth of backup supply before your first week back provides real peace of mind. A small stash covers the gap if your first few pump sessions at work produce less than expected while you adjust to pumping in a new environment. Starting to build your stash around 4 to 6 weeks postpartum, once breastfeeding is well established, and adding one pump session per day in the morning when supply is highest is a manageable approach. Visit the Storkpump Learning Center for a full guide on building a freezer stash without disrupting your nursing relationship.
4. Know Your Legal Rights
Federal law requires most employers to provide reasonable break time and a private space (not a bathroom) for nursing employees to express milk for up to one year after childbirth. The PUMP Act, which expanded these protections in 2023, extended coverage to salaried and exempt employees who were previously excluded. Knowing your rights before you return means you can advocate for yourself confidently if your employer is not familiar with the requirements. Your HR department should be your first point of contact. If you encounter pushback, the Department of Labor's Wage and Hour Division enforces these protections.
5. Scout Your Pumping Space in Advance
If possible, visit your workplace before your return to identify where you will pump, whether there is an outlet available, whether the room has a lock, and how much time realistically fits within your break schedule. Knowing the logistics in advance removes a significant source of anxiety from your first day back. If the designated space is a shared room or lactation pod, find out how to reserve it and what the protocol is for scheduling. If no adequate space exists, that is information you need before day one so you can work with HR to arrange something appropriate.
6. Pack Your Pump Bag the Night Before
A forgotten valve or a missing storage bag can derail an entire pumping day. Create a checklist of everything that goes in your pump bag and pack it the night before every workday. A complete bag includes your pump, power adapter or charged battery, all tubing and flanges, valves and membranes, storage bags or bottles, a cooler bag with an ice pack, a small bottle brush if you plan to wash at work, breast pads, and nipple cream. Many moms keep a duplicate set of small parts at work so a forgotten piece is never a crisis. Visit the Storkpump FAQ for a full list of recommended pump accessories.
7. Plan Your Pumping Schedule Around Your Work Day
To maintain supply, the number of times you pump at work should roughly match the number of feeds your baby would be having during those hours. For most moms returning full time, that means 2 to 3 pumping sessions in an 8-hour workday, spaced roughly every 3 hours. Map this out against your actual meeting schedule before you return so you know which windows are realistic and can communicate your schedule to your manager. Block time on your calendar so pumping sessions do not get accidentally overbooked. Consistency matters more than perfection, but having a plan dramatically improves your chances of sticking to it.
8. Line Up Your Support System
Returning to work while breastfeeding is more sustainable with support. Make sure your partner, caregiver, or family member who feeds the baby during the day is comfortable with bottle preparation, paced bottle feeding, and proper milk storage and thawing. Share the CDC breast milk storage guidelines with anyone who handles your expressed milk. And have the contact for a Storkpump IBCLC saved before you go back. Supply dips, engorgement, or unexpected challenges are common in the first few weeks back, and having professional support available means you can address issues quickly before they escalate.

Frequently Asked Questions
How much milk should I be pumping per session at work?
Output per session varies widely, but a general benchmark for moms with an established supply is roughly 2 to 4 ounces per breast per session, or 3 to 5 ounces total from a double pump session. What matters more than hitting a specific number is that your total daily pumped volume is meeting your baby's daily intake needs, which for most babies between 1 and 6 months is approximately 25 ounces per day. If your output feels consistently low, check your flange fit, pump settings, and hydration levels before assuming a supply problem.
What if my supply drops after I return to work?
A temporary dip in the first week or two back is common as your body adjusts to a new routine and pumping environment. Maintaining your pumping schedule consistently, staying hydrated, and nursing more frequently in the evenings and on weekends to compensate helps most moms stabilize supply within a week or two. If the dip persists, adding a pumping session before bed or in the early morning, using hands-on pumping techniques, and connecting with an IBCLC are the most effective next steps.
