Reasons for Uneven Milk Supply 

The reason you may have one breast that produce less milk than the other can be pretty straight forward for the most part.

When one of your breasts has began to fall short in milk production, this is usually due to the supply and demand trigger not being stimulated enough.

For instance, if you are nursing and your baby tends to favor one breast over the other – the breast getting the most action will undoubtedly produce more milk.

This is the equation of supply and demand.

If you are breast pumping to maintain your supply, a slight variation in milk production from breast to breast can be completely normal and expected. 

However, if you are noticing that one breast is producing significantly less milk than the other, it is time to address the discrepancy and put some of these tips into practice.

How to Increase Milk Supply in One Breast

When one breast produces less milk than the other we can determine that the demand switch on that breast is in a down throttle.

The easiest way for how to increase milk supply in a slacker boob is to re-implement a nursing or pumping routine that will signal a surplus supply and demand response out of the underproducing breast.

Power Pumping to Even Out Milk Supply

Lets begin correcting this uneven milk supply with a targeted breast pumping routine.

If you are exclusively pumping, the method best used to correct this issue is quite simple, it just takes a little extra time.

I would recommend performing your pumping routine as usual, pump both breasts at the same time.

Once you have finished fully emptying both breasts, go ahead and wait 10 minutes and then begin again on the slacker boob.

How to power pump just one breast

Pump 20 min. / Pause 10 min. / Pump 10 min. / Pause 10 min. / Pump 10 min. = Finished 

As you can see, this is a traditional power pumping schedule. However, you are just performing it on the breast that is producing less milk than the other.

The reason you pause in between, is because every time you resume pumping, there may be another half an ounce or so waiting to be expressed. 

Every extra drop you get through this strategy will eventually begin to tell your lazy boob it needs to catch up!

Best Techniques to Correct Uneven Milk Supply

In congruency with the breast pumping routine demonstrated above, you can also add other therapeutic remedies into your slacker boob solutions. 

You’ll find them below.

Use Heat

Heat is a wonderful tool that can help to promote the expression and production of more breast milk. Try taking a hot shower before you pump and really focus that water flow onto your under-producing breast. 

You can also use a designated tool that is designed to add heat during a breast pumping session to aid in milk letdown.

Like this awesome hands-free heating pack I found for you on Amazon.

Try Some Vibration 

Did you know that vibration is an extremely effective tool to use while pumping?

Vibration on the breasts before and during your pumping session can dramatically increase milk flow, help eliminate clogs and even trigger multiple letdowns.

Using this LaVie Lactation Massager (10% off LOVEOURLITTLES10) on the breast that is producing less milk will increase the breast tissue stimulation and hopefully signal a boost in breast milk supply.

Breastfeeding with a Slacker Boob

This next section will be focused primarily on the exclusively nursing mom who notices an uneven supply and how to fix lopsided breasts while breastfeeding.

How to Know if You Have One Breast Producing Less Milk while Exclusively Nursing

  • You may find that your baby favors one breast over the other.
  • Your baby may put up quite a fight when you attempt to feed them on the breast that is producing less milk. 
  • Look in the mirror – are your breasts two totally different sizes when they are full?

At any rate, the question is, how do you fix lopsided breasts when exclusively nursing?

This issue could have arose in any innocent way, forgetfulness. Yes, maybe you just couldn’t remember what side you nursed on last and therefore, may have given one breasts a little too mush attention too many times.

If this is the case, these cute little breastfeeding reminder tabs should do the trick!

Nursing Habits That May Have Contributed to a Slacker Boob

You may have acquired a slacker boob due to nursing too frequently on one side just because it’s more comfortable. I always felt more comfortable nursing on my right side.

That is until my child with gums made of razor blades eventually wore a deep gash half way through my nipple. T.M.I.?

Which led me down the long and winding road of exclusively pumping. 

If you are looking for more guidance, support and confidence with your breast pumping and milk supply, I would recommend this inexpensive and wonderful online course, The Ultimate Exclusive Pumping Class by Milkology.

Rectifying this cause may be as simple as switching up your breastfeeding position. Such as, laying down on your side to nurse (my personal favorite). 

Try a nursing pillow that will give you more support. I used the Boppy at first, but I didn’t actually find it to be as ergonomically accommodating as I would have hoped.

Try instead the My Brest Friend nursing pillow. I have seen and heard a lot of really positive reviews about this particular nursing pillow and it does look very supportive.
