How do you know if you have an oversupply of breast milk while exclusively pumping?

Basically, if you make more breast milk than your baby eats, you're an oversupplier.

There are three basic categories of supply when it comes to exclusive pumping:

Undersupplier (or Underproducer): Makes less breast milk than baby eats
Just Enougher: Makes about the same as what baby eats, maybe with a small buffer of a few ounces
Oversupplier (or Overproducer): Makes more than a few ounces more than what baby eats.

This means that two women can pump the exact same amount of milk, and one can be an undersupplier and one can be an overproducer!

Say that Sally pumps 30 oz per day, and her baby eats 25 oz. Sally is an oversupplier. Meg pumps 30 oz per day, but her baby eats 35 oz. Meg is an undersupplier.

What issues can an oversupply of breastmilk cause?

There are a few issues that having an oversupply can cause. Often, these issues present less of a problem for exclusive pumpers than for nursing mothers, but they still exist.

Possible complications of oversupply can include:

Forceful letdown

Sometimes, when a mom has oversupply and her milk lets down, too much can come out at once for baby to handle. This can be frustrating for the baby, especially since they often get sprayed in the face.

If you're exclusively pumping, this will not be a problem for you! Your breast pump can handle whatever letdown you give it.

Foremilk/hindmilk imbalance

Foremilk is the milk at the start of a session, and tends to be less fatty than the hindmilk at the end. If a baby fills up on foremilk (because there is so much of it) before she can get to the hindmilk, this can cause issues like green poop and fussiness. (More info on foremilk/hindmilk imbalance here.)

This tends to be less of an issue for moms who are exclusively pumping, because the milk is all mixed together in a bottle, but some moms do still struggle a bit. Many find that the pitcher method is helpful in managing foremilk/hindmilk imbalance when exclusively pumping.

Recurrent clogged ducts/mastitis

Any breastfeeding mom – undersupplier, just enougher, or oversupplier – can struggle with recurrent clogged ducts or mastitis. However, it may be a bit more of a struggle for overproducing moms because they have more milk that needs to be removed when they lactate.

(Cutting a nursing or pumping session short can sometimes lead to milk getting "stuck.")

How to decrease milk supply when you're not weaning (versus when you are weaning)

If you're trying to decrease milk supply when you're NOT weaning, I would be really careful as you go about this. (In fact, if you're exclusively pumping, unless you are struggling with one of the above issues, I recommend NOT decreasing your milk supply – more on this here.)

I've ordered the below strategies from baby steps to most effective. If you're not weaning, I would start with the baby steps.

If you are weaning and trying to completely dry up your milk supply, feel free to go all out and choose whatever method you'd like. You might want to start from the end of the list, because those strategies will be most effective.

How to Decrease Your Milk Supply

Here are several things that you can do to reduce your milk supply, from least drastic to most effective. If you are not weaning and just trying to curb production, go slowly and watch how your body is responding before continuing.

1. (Gradually) Pump Less Milk

The most important thing that you can do to pump less milk is … pump less milk.

Breastfeeding is a supply and demand process, so the more milk that you remove from your breasts via the pump, the more milk your body thinks it needs to make. The trick is to pump less milk gradually, so that you don't run into the problems of clogged ducts or mastitis as you are in the process of reducing your milk supply.

There are a few different ways that you can approach this, and I've covered them in more detail in a post on dropping pumping sessions. For example, you can pump for less time in each pumping session, you can slowly reduce the volume that you pump in a given pumping session, or you can completely drop a pumping session.

If you have had a clogged duct or mastitis before, I would definitely recommend focusing on reducing the volume you pump. With this method, you pick one pumping session and slowly reduce the amount that you pump during that session.

For example, let's say that at your 3pm pumping session you normally get 8oz, and you're trying to reduce your supply. On the first day, you'll pump 7oz and then stop, no matter how much time it's been.

The next day (or you can wait a couple of days to allow more time for your body to adjust, if you'd like), you can take it down to 6oz, and so on, until you're pumping the amount you want in that session. Then, once your body has adjusted, you can repeat the process with other pumping sessions until your supply is where you'd like it to be.

You can also try pumping for less time. One approach is to completely drop a pumping session without adding the time of the dropped pump back into your remaining pumping session.

Here is more information on how to drop a pumping session.

2. Try Cabbage Leaves

Who doesn't want to have a salad in their bra? There hasn't been a lot of research done to showwhy this works, but it is often recommended by lactation consultants and doctors to provide relief from engorgement and reduce milk supply.

One theory is that the amnio acids in the cabbage help to decrease tissue congestion by opening capillaries and improving the blood flow in and out of the engorged breast, relieving inflammation and allowing the milk to flow freely.

I wrote a step-by-step overview of how to use cabbage, but the short version is: to use a cabbage leaf, wash it and slice off the tops of the vein with a knife. Then put it in your bra. You'll want to leave it in there until it wilts – about 20-30 minutes – and repeat often.

Women who have engorgement are instructed to do this three to four times in a 24 hour period to reduce engorgement without losing milk supply; since you are trying to decrease your milk supply, you may want to do it more than that. Again, just be careful not to overdo it if you're not weaning; once you start to see results I would pull back a bit and reevaluate.

You can chill the cabbage leaves in the refrigerator if you prefer, but they don't need to be chilled to work.

(If you have cracked or bleeding nipples, hold off on using cabbage until that has healed, or, if possible, you can just place the cabbage on areas that are unaffected.)

In addition to cabbage, I wanted to mention Cabocreme (a cream with concentrated cabbage extract). It's is more expensive than cabbage, but lots of moms in our Facebook group find it easier to use and see the same results.

3. Eat Peppermint

Peppermint is an herb that may decrease milk supply in larger doses.

A few peppermint candies or menthol cough drops probably won't make your milk supply plummet, but in larger quantities, it might have an effect. Start small and see if you notice your milk supply starting to drop.

4. Eat or Drink Sage

Like peppermint, sage is one of a few herbs that can decrease milk supply. There are a few different ways that you can consume it; you can use dried sage from your spice rack to make tea or ingest directly, or you can take capsules.

To make sage tea, put one teaspoon of dried sage in one cup boiling water and steep for 15 minutes. You can also eat it directly by mixing it in with other foods, or, if you don't like the taste, putting about 1/4 tsp of it on something sticky (like honey on a very small piece of bread) and try to swallow it like a pill.

Both of these options sound totally disgusting to me, so I would probably just go with the capsules.

5. No More Milk Weaning Tea

This tea contains sage, peppermint, and parsley, and is intended to help speed the weaning process. Basically, it's a packaged way to get the more powerful anti-milk supply herbs.

This might be a little more palatable than sage capsules or tea or eating large quantities of candy canes. Again, start slowly.

6. Birth Control Containing Estrogen

Birth control products that contain estrogen, such as Nuva Ring or oral combination birth control pills, may have a negative effect of breast milk supply.

If you are weaning and planning to start taking birth control with estrogen anyway, it might make sense to time it so that you start your new birth control with when you start weaning.

(I wouldn't recommend trying this unless you are weaning: if it reduces your supply too much you'd have to stop taking it and switch to something else, and that can cause a lot of upheaval and possibly an unplanned pregnancy.)

7. Take Sudafed

For some women, taking pseudoephedrine (the active ingredient in Sudafed) will reduce milk supply – a small study of lactating women showed that one dose of Sudafed reduced milk supply over the next 24 hours by 24%.

Unless you are weaning or have significant negative effects from oversupply, use caution with reducing supply with Sudafed, as the effect will vary from woman to woman, and you don't know how it will affect you until you try it.

In the United States, Sudafed is sold in most pharmacies behind the pharmacy counter, but you don't need a prescription.
