The Benefits of Fully Emptying Your Breasts 

Why do you want empty breasts in the first place other than to avoid complications and a decrease in milk production?

There are actually several interesting benefits to routinely empty breasts and those are as follows:

  • Empty breasts help to increase the fat content in your breast milk.
  • Emptier breasts signal a stronger supply and demand signal and an increase in milk supply.
  • Some studies show that emptier breasts more often help to improve the nutritional quality of the breast milk.

What Happens if I Don’t Empty My Breasts?

Did you know that your breasts are never truly empty of breast milk? This is because while you are lactating, your body is always in milk-making mode.

Think of it this way, it’s just like a running faucet. However, it is still important to remove as much sitting breast milk from the breasts as possible.

Having said that, what happens if you aren’t able to fully drain your breasts of breast milk after you pump or breastfeed?

Not Fully Emptying Your Breasts Could Lead to Clogs and Mastitis 

A clog is no fun and you know what it can lead to, right ladies? Mastitis? Yep, unfortunately that’s right. Mastitis, the three syllable word all breastfeeding moms fear!

Mastitis is inflammation of the breasts that causes pain, swelling, redness and sometimes an infection.

Signs and Symptoms of Mastitis:

  • Breast tenderness
  • Warmth
  • Redness
  • Thickening of breast tissue
  • Pain
  • Burning Sensation 
  • Fever 
  • Feeling flu-like symptoms

Causes of Mastitis:

  • Clogged Milk Duct: Mastitis can be caused by backed up breast milk that sits too long in the milk ducts, causing a nasty clog that can lead to an infection.
  • Bacteria: Bacteria can enter the milk ducts through contact with baby’s mouth, pump parts, and not fully emptying breasts leading to a breeding ground for bacterial growth.

How do I Prevent Myself From Getting Clogs?

Now that we’ve covered what can go wrong by failing to fully drain your breasts properly, let’s jump into the other pumping tips I promised to share with you today!

How to Know When My Breast is Empty When Pumping?

Let’s first make some notes on how to tell if your breasts are empty when pumping. It is important to note that there is a difference between breasts feeling full due to sitting milk versus breast tissue that may be inflamed. 

Be sure to evaluate that carefully before you attempt an aggressive routine of trying to drain them further.

The Signs of Empty Breasts:

How do you know your breast is empty after pumping? Here are some signs you can look for to help you determine if you efficiently removed your sitting breast milk:

  • Your breasts will feel flat and flaccid (floppy).
  • It has been over 10-15 minutes since your last let-down and the milk has stopped flowing.
  • Hand expressing is getting little to nothing extra out.

11 Tips to Help Fully Empty Breasts with a Pump

In this section, we’ll address each tip thoroughly to help you best empty your breasts with a pump.

I was able to come up with these tips based on the expertise of many exclusively pumping moms, as well as my own experience.

1. Hand Express While Pumping

This tip is a must learned skill for pumping moms! A good pump can do a lot of the work for you, but sometimes they still need our assistance. 

Hand expressing is a superb way of manually forcing breast milk out of sticky and stubborn milk ducts.

It is a good idea to always massage while pumping and finish with hand expressing.

In fact, using a breast massaging tool such as this lactation massager will help make this task much easier.

This is a good place to recommend the added help and expertise of an online course that will guide you through all of these pumping techniques. 

Milkology’s course, The Ultimate Exclusive Pumping Class is where I would recommend you begin building up your pumping and lactation confidence.

How to Hand Express While Pumping

To use this tip to ensure you are fully emptying, simply apply massaging pressure and work your way down your breasts toward the nipple as you pump.

I find that this method works best if you are pumping one breast at a time without a pumping bra getting in the way.

2. Initiate Multiple Let-Downs

Triggering multiple let-downs while pumping is a key tactic to ensuring you are fully emptying your breasts during a pumping session. Here are some ways you can trigger a let-down in case you want to shoot for more milk removal and those are:

3. Use A Manual Breast Pump

The usefulness of a manual breast pump is sometimes overlooked, but don’t disregard it as an afterthought.

A manual breast pump is actually really good at getting out clogs too!

If you feel like you may still be full after the use of your everyday pump, bust out the manual pump for a few minutes and see what happens!

4. Change Positions of the Flange

This is a really effective pumping tip when you see milk ceasing to flow, but you think you could still drain your breasts some more. 

Simply begin to move the flange around your breasts and apply tension to different sides where you feel like you could possibly pump more milk from.

I can attest to this tip, as it worked every time for me and I could not go a pumping session without performing it.

5. Dangle Pump

What is dangle pumping? Dangle pumping is pretty much as it sounds.

To perform, you literally dangle the flange from your breasts as you pump, using gravity to help further empty the breasts or to achieve multiple let-downs.

This technique takes some practice, but once you have it mastered, it will be one of your favorite pumping hacks to use!

6. Add Heat

Using moist heat especially, helps to loosen up the milk ducts and create a smoother flow. You can use warming lactation massagers, a warm moist wash cloth or take a hot shower.

Remember to pump directly after using heat for maximum results.

7. Try Different Pump Settings

You may want to experiment with your pump’s settings to see if switching things up will help you have more letdowns and in turn pump out more milk.

As an example, most breast pumps have a “suckling mode” which mimics a baby’s nursing motion (like these Liquid Shield Kits from Pumpables).

This setting can help you achieve multiple letdowns by returning to it after milk has stopped flowing.

8. Nurse On One Breast Until Breasts Empty

If you are nursing, let your baby fully drain one breast before offering the other.

Your baby’s ability to empty your breasts is more effective than any other method or tool. After all, that is what they were designed for!

9. Try Sunflower Lecithin

I’ve written about the power of sunflower lecithin a lot of times before, but that’s because it really was a game changer for me! It came in especially handy when I was in the process of weaning from the pump.

It’s not uncommon for milk to become a little sticky at times. This could be a result of your breastfeeding diet or hormonal changes.

Sunflower Lecithin (linked at Amazon) helps to prevent sticky milk ducts that can make it hard for breast milk to flow as easily. 

Always consult with your doctor before taking any type of supplements or medications while breastfeeding.

10. Dry Your Pump Parts

While pumping, it’s normal that your flanges will begin to accumulate some moisture.

If you notice the seal between your breasts and flange isn’t quite solid and there is a loss of suction, try wiping down the insides of the flanges and start again. 

I had to regularly do this throughout my entire pumping sessions. It’s a super simple task that can have a big impact!

My pumping course (free when you purchase any course from this list) has a complete guide with printables on how to properly clean and care for all of your pumping parts and equipment.

This information is so nice to know without having to scourer the whole internet looking for it or doing it wrong and leaving room for common, but potentially dangers pumping mistakes

11. Change Your Breast Pump Parts

If you are not fully emptying during your pumping session, your breast pump parts may be causing the problem.

You should be changing out your pump’s parts regularly to keep your breast pump performing optimally

12. Use A More Powerful Pump

If you are consistently changing your pump parts, but are still having a hard time feeling fully empty when you pump, it may be that your breast pump is not performing up to par.

To help you determine if you are missing out on a better milk supply, see this breast pump buying guide with pumps for every occasion and need. 

You may be using the wrong breast pump! 

A powerful pump doesn’t have to mean a big pump either!

If you are looking for a compact, quiet and extremely powerful pump, you must check out the BabyBuddha! This little portable breast pump is my top recommendation. 

You can shop for the BabyBuddha at LaVie with a 10% discount using the code LOVEOURLITTLES10!

It’s a quick and easy process that could save you big money!
