It is very normal when one breast produces more milk than the other. Maybe there are a few “chosen ones” in this world that do not have the problem of asymmetrical breasts.

But for the rest of us, we have a normal difference in size between our two breasts. This is a super common thing and when we are breastfeeding the difference becomes even more pronounced. Sometimes to the point of being humorous.

What is not so funny is when you have one side that supplies an abundant amount of breast milk and the other side is what we refer to as a “slacker boob”.

But that term is a little negative. So for the purposes of this article and promoting positivity, let’s refer to it as “the underdog”. 

In this article, we are going to look at why this may happen and what you can do to fix it. Let’s get started, and get that underdog back in the game!

What to do When One Breast Produces More Milk than the Other

For me, the over-achiever is the right side. It has topped the milk output charts at 10 ounces one morning. Meanwhile, lefty has maxed out at 3 ounces *wah-wah*.

What makes for this huge difference? A few things.

Let me give you some insight as to why this happens and what you can do to help your underdog make gains. *flexes muscles*

1. Always start breastfeeding on the underdog side.

When your baby first starts nursing they are most hungry at that time. So the sucking will be stronger and more rapid, which will encourage the let down reflex more readily.

Obviously, you will need to switch your baby over to the other side to satiate their hunger, but if you get into the practice of starting on the underdog side you will begin to notice improvement in output.

Part of my problem was mostly feeding from the right side (the over-achiever) because it was easier for me. And then over time, the milk supply in my left side decreased because I was nursing less from that side.


2. Pump from the underdog side for at least 5 minutes after each feeding session.

This may not produce any milk at first, but what it will do is give your breast the sensation that it should be producing more. If you do this a few times a day, you will see an improvement within a week or less.

3. Power Pumping

See also, power pumping. You may want to include this into your pumping schedule to help increase your milk supply overall.

Power pumping is a pumping technique that mimics cluster feeding when an infant is going through a growth spurt. You increase the frequency of pumping in short increments. Putting more demand on your breasts, and in turn making more milk.

The beauty of my power pumping technique is that it takes much less time than the old way. Learn more about my 20-minute power pumping here, and start producing more milk!

 4. Use [this] hands-free pump on the underdog side when breastfeeding on the opposite side.

I never realized how much milk that would accumulate by using this pump. It is similar to the Haakaa pump, but these are better priced for what you get.

It includes:

  • A milk stopper- which prevents any spilling once your done
  • A storage cover
  • AND a cute travel pouch.

I use this pump and have gotten amazing results! Usually getting 2-3 ounces extra! That is milk that would have gone wasted.

I mostly use the hands free pump first thing in the morning when feeding my baby. After having a few soaked shirts from the let down on the non-nursing side, I decided it was time to figure out a way to save those extra ounces! You must give this item a try!

5. Drink more water.

Where there is water, there can be milk. You can’t pull from a dry well.

(speaking in the proverbial sense)

Your milk is the water and your body is the well. And you must put good in to get good out!

On average you should be drinking, at least, 8 glasses (8 ounces each) of water per day. Drink enough so your urine is clear to pale yellow. It should not be concentrated or dark yellow.

If one breast produces more milk than the other, don’t get discouraged.

There was a point earlier on in my breastfeeding journey where I almost gave up because my supply had dropped so low.

But reaching that point was exactly what I needed to kick myself in the butt and give it my all. I didn’t want to stop breastfeeding so early. I was determined to fix the problem!
