A Parent's Guide to Returning to Work While Breastfeeding
Going back to work after maternity leave is one of the most emotionally charged transitions in early parenthood. You're navigating a new schedule, a new routine, childcare logistics and the very real question of how to keep your breastfeeding relationship going when you and your baby are no longer together all day. *Cue all the emotions
The good news: it absolutely can be done. And the more you prepare ahead of time, the smoother that first week back tends to go. Here is everything I walk my clients through when we're getting ready for this transition.
Preparing Your Body and Your Baby for More Separation
Before your first day back, it helps to give both you and your baby a chance to practice being apart. If possible, try introducing some time away in the days or weeks leading up to your return. This might mean a trial day at daycare, a few hours with a caregiver while you run errands, or simply having someone else do a feeding while you step out.
This gradual separation gives you & your baby time to adjust, gives your caregivers a chance to practice and gives you the opportunity to identify any hiccups before they happen on a Monday morning when you're already running late.
Establishing Your Pumping Routine
Once you're back at work, the goal is to remove milk from your breasts roughly every 2.5 - 3.5 hours throughout the workday. This frequency mirrors what a nursing baby would do and is what tells your body to keep making milk at its current volume.
Skipping sessions, cutting them short, or going long stretches without pumping sends the opposite message. Your body reads decreased demand as a signal to decrease supply. Protecting those pump sessions is one of the most important things you can do for your milk production.
Under federal law, employers are required to provide nursing employees with reasonable break time and a private, non-bathroom space to pump. Know your rights and have that conversation with your employer before you return if you haven't already.
Get to Know Your Pump Before You Need It
There is nothing worse than sitting down for your first pump session at work and realizing you don't know how to adjust the settings, something isn't fitting right, or a part is missing. Set your pump up at home well before your return date. Use it. Get comfortable with it. Make sure it is working efficiently for your body.
Two things I always emphasize with my clients:
Flange fit matters more than most people realize. The flange is the cone-shaped piece that fits over your nipple and areola. If it is the wrong size, pumping can be uncomfortable, inefficient, or even damaging over time to your nipples or your milk supply. Your nipple should move freely in the tunnel without your areola being pulled in, and there should be minimal rubbing along the tunnel walls. Many people are not using the size that came in the box. An IBCLC can help you find your correct fit.
Have two sets of pump parts. I recommend having at least two complete sets of flanges, valves, and membranes so that you are not scrambling to wash parts between every single session at work. Store used parts in a clean zip bag in the refrigerator between daytime sessions if you prefer, or simply rinse and air dry. Having a backup set means one less thing to stress about in an already full day. You could even encourage your employer to put a bottle washer and sterilizer in the pumping room.
Practice Bottles With Your Baby Before You Go Back
If your baby has only ever nursed directly at the breast, the introduction of a bottle is a new skill for them and it should not happen for the first time the morning you return to work.
Start offering a bottle two to four weeks before your return date. And keep at least one a day, or every other day, to allow baby to retain the skill. It does not need to be a full bottle. It can even be simply half an ounce so they can practice suckling on the nipple. This gives you enough time to troubleshoot if your baby is resistant, which some exclusively breastfed babies can be. It also helps you identify whether there are any signs of feeding difficulty, such as gagging, coughing, milk spillage, or significant fussiness, that might be worth addressing with an IBCLC before the stakes are higher.
Some babies take to bottles easily. And sometimes babies need a specific bottle to nurse well from, and we would only find that out through trial and error. Others need time and patience. Knowing which category your baby falls into ahead of time is a gift to your future self.
Talk to Your Childcare Provider About Milk Handling
Before your baby starts in care, sit down with your provider and go over a few important things:
Breast milk storage guidelines. Freshly pumped milk can be kept at room temperature for up to four hours, in the refrigerator for up to four days, and in a freezer for up to twelve months (though six months is ideal for quality). Make sure your provider knows how to safely thaw and warm frozen milk, and that breast milk should never be microwaved.
Paced bottle feeding. This is one of the most important conversations you can have with your childcare provider. Paced bottle feeding is a technique that slows the flow of the bottle to more closely mimic the pace and effort of nursing at the breast. It gives the baby more control, reduces overfeeding, and helps protect the breastfeeding relationship.
Why does this matter? A bottle can deliver milk very quickly and with much less effort than nursing. Without pacing, babies can easily take more than they need simply because the milk is flowing and the sucking reflex is active. That means you come home to a hungry baby, pump more to keep up, and gradually feel like you are always behind.
How much milk does a breastfed baby actually need at daycare? This surprises a lot of parents. Most breastfed babies take approximately 1.25 to 1.5 ounces of milk per hour of separation. A baby who is away from you for eight hours needs roughly ten to twelve ounces, not sixteen or more. This is helpful as well because you only need enough milk for the first day. If you only have 12 oz set aside, you should be more than fine for that first day back at work. This is significantly less than formula-fed babies typically take in bottles, and it means you do not need to have a massive freezer stash to make this work. Paced bottle feeding helps ensure your baby actually takes that appropriate amount rather than significantly more. Ensuring you have a proper slow flow bottle is also important. No Comotomo please!!

Tips for Emptying Your Breasts Well When You Pump
Pumping at work is not just about removing milk. It is about sending your body the right signals to keep producing. Here are the strategies I consistently recommend:
Bring your baby with you, at least visually. Keep a photo or short video of your baby on your phone and look at it while you pump. Smell a worn onesie or a burp cloth that smells like them. This is not just a sentimental practice. It genuinely helps trigger the hormonal response, specifically oxytocin, that causes your letdown. Many parents notice a significant difference in how much they pump when they are emotionally connected to their baby during the session versus when they are distracted or stressed.
Use hands-on pumping. Breast compression during pumping, gently compressing and massaging the breast while the pump runs, helps the pump drain your breast more completely. Research has shown it can significantly increase the amount of milk removed per session. The pump alone does not always do a full job. Your hands are part of the process. This is a great demonstration of how to do hands-on pumping.
A note on wearable pumps. Wearable pumps have been a meaningful development for working and pumping parents, and I understand why they are appealing. However, I consistently see situations where wearable pumps do not empty the breast as effectively as a traditional wall pump. Over time, incomplete emptying can lead to a gradual decline in supply, recurrent clogged ducts, or mastitis. If you use a wearable pump, I strongly recommend also having access to a hospital-grade or double electric wall pump, particularly for at least some of your sessions. Think of the wearable as a convenient option, not necessarily your primary workhorse. You could even encourage your employer to invest in a multi-user hospital-grade electric pump for the pumping room at work.
You Do Not Have to Navigate This Alone
Returning to work while breastfeeding is one of the most common times I see parents start to struggle with supply, pain, or just the sheer overwhelm of trying to keep everything going. Please know that these challenges are normal, and they are also often very solvable with the right support.
Reach out to your IBCLC if you notice:
Milk supply decreasing or not meeting your baby's needs at daycare
Recurrent clogged ducts or mastitis
Nipple pain or damage from pumping
Concerns about your baby's bottle feeding or intake
Questions about your pump, flange fit, or pumping output
You do not have to wait until something is a crisis. A quick check-in before you go back, or in those first few weeks of the new routine, can make an enormous difference.
