How to Increase Milk Supply When Pumping: What Actually Worked (From a Mom Who Pumped for 26 Months)

And honestly? Social media makes it worse sometimes. 

One mom is freezing 40 ounces a day (or more.) 

Another is showing a deep freezer stash or 5. 

Another says she drinks one magical drink and suddenly makes enough milk for triplets. 

And then you have the weird medicine many are taking. 

Meanwhile you are sitting there trying to figure out if your baby is still hungry or just being a baby. If you have any time before your next pump or attempt to latch to eat or maybe shower. I know because I have lived both sides of this. 

My Real Experience: Exclusive Pumping for 26 Months, Then Nursing 

I exclusively pumped for 26 months with Sean. Twenty six. Entire. Months. I learned breastfeeding through pump parts, alarms, MOTN sessions, thrush, poor sizing, and measuring my worth in ounces. I knew exactly how much milk I made every day because it was all right there in bottles staring back at me. 

Then I had Ruby and suddenly everything changed. Nursing directly felt beautiful but also terrifying because I couldn’t SEE the ounces anymore. I couldn’t measure every feed. I couldn’t track everything the way I did before. I had to actually trust my body and honestly I didn’t realize how much exclusive pumping had trained my brain not to. 

There are still days now where Ruby cluster feeds and my brain immediately goes: “Great. I must make no milk.” 

Even though logically I know better. 

Low Supply Anxiety vs. Actual Low Milk Supply 

That’s the thing nobody really talks about. Sometimes low supply anxiety and actual low supply are not the same thing. 

And yes, sometimes supply issues are real. But I think moms deserve honest conversations about what actually helps versus what mostly just drains your wallet and mental health. 

How to Increase Milk Supply When Pumping (The Honest Answer) 

For me personally, the biggest thing that ever increased my supply was not supplements. It was consistency. 

I know that answer is boring. I wish I could tell you it was one special drink or one specific snack or some lactation brownie recipe that changed my life. But every single time my supply increased, it came down to milk removal. That was true when I EPed. And it is still true now nursing Ruby. 

1. Consistent Milk Removal Is the Real Answer 

When I consistently removed milk, my body responded. When life got chaotic and I skipped pumps or stretched feeds too long because I was overwhelmed, exhausted, working, parenting, trying to survive, my supply dipped. 

And motherhood is chaotic. Especially when you are also trying to financially support your family, answer emails, cook dinner, be present for your older child, and somehow remember where you left your coffee. 

There were seasons with Sean where I was pumping in the car, pumping in bathrooms, pumping while crying, pumping on a boat, pumping while answering work messages because I genuinely believed stopping was not an option. 

And honestly? Looking back now, I wish I had given myself more grace. 

2. Stress Actually Does Affect Your Supply 

Because stress matters too. 

Not in the “your milk disappears instantly” way people online sometimes claim. But stress absolutely affects letdowns. It affects consistency. It affects sleep. Hydration. Eating enough. Your nervous system. 

I can always tell when I am running myself into the ground because my body responds before my brain wants to admit it. 

3. Eating Enough Food Matters More Than Any Lactation Supplement 

And can we talk about food for a second? 

I spent SO much money on lactation products in the beginning. 

Cookies. 

Supplements. 

Drinks. 

Powders. 

Teas. 

Some were good, perhaps just yummy. Some did absolutely nothing. Some honestly just gave me expensive pee. 

What helped me most? Actually eating enough food. Not surviving off water and toddler leftovers. 

Real meals. 

Protein. 

Water. 

Electrolytes. 

Breastfeeding makes me unbelievably hungry and I think a lot of moms accidentally under-eat because we are so busy taking care of everyone else. 

Here is the part I wish someone had sat me down and told me sooner: breastfeeding burns roughly 300 to 500 extra calories a day. That means most nursing moms actually need somewhere around 2,300 to 2,500 calories a day. Sometimes more depending on your body, your activity level, and how much milk you are making. The CDC backs up these general numbers too. 

Not less. More. 

This is general guidance, (so please talk to your doctor or a lactation consultant about what is right for you.) 

And I know diet culture has done a number on all of us. There is so much pressure to “bounce back” while your body is literally still making food for another human being. It is a lot. 

But under-eating tanks more than your supply. It tanks your energy. Your mood. Your letdowns. Your patience by 5 PM when everyone in the house wants something from you at the same time. 

When I finally started eating real plates of food, not just three bites of whatever Sean didn’t finish, my outputs got more consistent. Not overnight. But over time. Your body cannot make milk out of nothing. 

4. Get Your Flange Sizing Right 

Another thing I wish moms talked about more is flange sizing. Because why did nobody explain this sooner? I spent way too long uncomfortable while pumping thinking that was just part of the experience. Once I finally learned proper sizing, pumping became more effective AND less miserable. If you have never measured, sites like KellyMomhave solid resources on it. 

And when something hurts less, you are more likely to stay consistent with it. 

What Is a Normal Pump Output If You Also Nurse? 

I also think social media has convinced moms that huge pump outputs are normal when they often are not. If you nurse directly, pumping less than 4 ounces combined can be completely normal. Especially after feeding the baby throughout the day. 

The One Thing I Would Skip Next Time 

Honestly, one thing I would skip if I had to do this or any journey. STOP obsessing over every single ounce. Because I lost so much joy doing that. I spent so much time wondering if I was enough instead of seeing that my babies were thriving right in front of me. 

To the Mom Reading This 

And while yes, evidence absolutely matters and education matters and support matters, I also think moms need someone to say this: 

You are not a machine. You are a person feeding another person with your body while simultaneously carrying the weight of motherhood, work, relationships, dishes, bills, exhaustion, and life itself. That is huge. And honestly? I think most moms are doing far better than they think they are. 

FAQs About Increasing Milk Supply When Pumping 

How long does it take to increase milk supply when pumping? 

For me, every time my supply increased, it took consistent milk removal across several days before I saw the bottle output change. Your body responds to demand, but it is not overnight. Give it at least 3–7 days of consistency before deciding something isn’t working. 

Do lactation supplements actually increase milk supply? 

Some worked a little for me. Most just gave me expensive pee. The thing that consistently moved my supply was not a powder or a cookie. It was milk removal, eating real food, and managing my stress. 

How many calories should a breastfeeding mom eat per day? 

Most nursing moms need an extra 300 to 500 calories a day on top of their normal intake, which usually lands somewhere around 2,300 to 2,500 calories total. Sometimes more. Under-eating is one of the most common reasons supply quietly dips, and a lot of us don’t realize we are doing it. Talk to your doctor or a lactation consultant about what is right for your body. 

What is a normal pumping output? 

If you also nurse, 2–4 ounces combined per pump can be completely normal. Exclusive pumpers tend to pull more per session because the baby is not also feeding directly. Social media has skewed what “normal” looks like. 

How does flange sizing affect milk supply? 

The wrong size can leave you uncomfortable, drain inefficiently, and make you dread pumping, which leads to skipped sessions. Skipped sessions are the fastest way to tank supply. Proper sizing helped me remove more milk and stay consistent. 

Can stress really lower milk supply? 

Stress doesn’t make your milk disappear, but it absolutely affects letdowns, sleep, hydration, and how often you actually sit down to pump. All of that adds up.
