Pumping for Twins 101 – What You Should Know

As an expecting mother of twins, I know how challenging it can be to learn about the different aspects of parenting. One important area for many mothers is pumping for twins. It can be a daunting task, especially if this is a first-time experience. Having gone through this journey myself, I want to provide some insight into everything that goes into pumping for twins. In this article, I will share my advice and experiences so that other twin moms can feel more confident in their journeys.

What Type of Pump Do I Need?

As an expecting parent of twins, you know the importance of being prepared and understanding what is necessary to keep your babies safe and healthy. One of the items that often gets overlooked when preparing for twins is purchasing a pump. But with so many options available, how do you decide which one is best?

The type of pump you choose will depend on several factors such as your budget, lifestyle needs, and how long you plan to use it. If you don’t plan to exclusively breastfeed or if your schedule requires frequent travel, then a manual or battery-operated pump can provide convenience and portability at a fraction of the cost compared to electric models.

However, if you are looking for maximum efficiency in expressing milk from both breasts simultaneously to establish and maintain an adequate supply for both babies then an electric double-breast pump may be ideal for the task.

Breast Pump Flange Size

Pumping For Twins

When it comes to the size of your breast pump flange, you can’t go wrong with the standard 24-27 millimeter range.

As a new mom, I have found that this is the most comfortable and effective option. When it comes to picking out a breast pump and all its accessories, I know that there are many options available on the market. But one important accessory that should not be overlooked is the flange—the piece that attaches to your bottle and fits around your nipple.

The good news is that most breast pumps come with a universal flange size of 24-27 millimeters. This means you won’t need to worry about whether or not you picked out the right size for your unique shape and needs—it’s already an ideal fit!

When To Start Pumping

When considering when to start pumping, mothers expecting twins can feel a bit overwhelmed. Pumping can be intimidating and it’s important to find the best timing for both you and your babies. To get started on the right foot, here are some tips on when to begin pumping for your twins.

Pumping For Twins

Starting with a few short sessions of five minutes each day around the 2-4 week mark is a good way to get yourself used to the process and prepare your body for breastfeeding two babies at once. It’s also ideal for maintaining milk production as well as preventing any potential issues before they arise.

By incrementally increasing the duration of pumping as you go, you’ll find that by about six weeks into your pregnancy, you’ll be able to pump around 10 ounces per session – enough for both babies combined throughout the day!

How Much Milk Should I Be Producing for Twins?

As a mom of twins, I know the importance of pumping milk for my tiny babies. After all, I need to ensure that each baby gets enough nourishment throughout the day and night. Yet with two little ones on my hands, how much milk should I be aiming to produce?  

The answer depends on your breastfeeding needs as well as those of your babies. Typically speaking, when it comes to pumping for twins you should aim to pump at least double the amount you would normally produce for one baby. You may even want to increase this amount depending on what’s best for your situation – such as if you’re looking to have a stash ready in advance or if one twin is having growth spurts.

How To Encourage Letdown When Pumping

Many parents of twins who are pumping for their babies are often overwhelmed by the amount of milk needed to feed two, or more, infants. It can be difficult for a mother to produce enough breast milk for both children, but there are ways to make sure that she can let down and pump enough milk.

The first step in encouraging letdown while pumping is understanding how the process works. When baby nurses at the breast, the natural hormones oxytocin and prolactin help stimulate the production of milk and allow it to flow.

The same hormones can also be stimulated when pumping by taking deep breaths, focusing on images of your babies, or other positive thoughts while you pump. Additionally, keeping your environment relaxing can also help with letdowns: dim lights, calming music, or lavender oil may all assist in letting down more quickly when pumping.

How Many Times Per Day Should I Pump for Twins?

Expecting twins can come with many questions and concerns, including how often you should be pumping breast milk for them. While the answer will vary depending on your lifestyle, there are some general guidelines to keep in mind.

Pumping For Twins

The American Academy of Pediatrics recommends that mothers with twins pump milk every 2-3 hours during the day to establish a good milk supply and feed both babies enough nutrition. This schedule also allows you to maintain an ample supply of frozen breast milk for later use if needed. Keeping this schedule can be difficult, but it’s important as frequent breastfeeding or pumping helps to ensure that your babies get all the nutrients they need.

In addition, it’s important to understand that newborns have small stomachs so they need their nutrients more frequently than older infants do.

How Long To Pump Per Session

Pumping for twins is slightly different than pumping for one baby, as it may take a little longer. Generally, moms of twins are encouraged to pump for 15-20 minutes per session. This is because it takes some time for all the milk ducts to empty, and when you’re feeding two babies, there is more milk that needs to be produced. Even if the first session only lasts 10-15 minutes, pump at least one more time on the same side to fully empty your breasts and make sure both babies get enough nutrition.

How To Combine Breastfeeding and Pumping

Breastfeeding and pumping can be an overwhelming prospect, especially when it comes to twins. However, combining the two is possible with a few simple tricks. Knowing how to balance motherhood and breastfeeding can help make life a little easier for new moms of twins.

For moms who choose to breastfeed their babies, pumping is key in providing milk for both twins. After establishing a regular breastfeeding routine with one baby, start introducing the pump about one week after birth for the other twin.

Pumping will help maintain the milk supply and provide plenty of milk for both babies when you’re not available to nurse them directly. A double electric breast pump is recommended as it will allow you to pump from both breasts at once – cutting down on time and allowing you to multitask while expressing milk from your body.

Can You Exclusively Pump for Twins?

Exclusively pumping for twins can seem like an overwhelming task, but it’s certainly doable with the right preparation and knowledge. It’s important to have a plan in place and to be aware of the demands that come along with exclusively pumping milk for two babies.

The key to success is having a well-thought-out plan on how you will manage your time when it comes to pumping milk, collecting milk, storing milk, and feeding it throughout the day. It’s also important to be realistic about how much you can physically pump each day. And make sure you prioritize taking care of yourself too by getting enough rest and staying hydrated. You may find that investing in a double electric breast pump or two single breast pumps helps save time as well as keep your sanity intact.

How To Clean Breast Pump

Pumping For Twins

Knowing the proper way to clean your breast pump is essential for ensuring your babies are getting only the safest and freshest milk. Here’s how you can easily clean your breast pump after each use.

Begin by separating the parts that were in contact with the milk from those that weren’t. Place all of the pieces in hot soapy water and let them soak while continuing with other cleaning tasks, such as washing bottles and nipples. Once they have soaked, rinse all of the pieces thoroughly using hot water before drying them off with a clean cloth or paper towel. Afterward, make sure all of the pieces are completely dry before reassembling them back onto your breast pump.

Breast Milk Storage Time

When it comes to pumping for twins, knowing the right breast milk storage time is essential. Breast milk has a high nutritional content and is easily digested by babies, making it the perfect source of nutrition for your little ones. However, if stored incorrectly, breast milk may spoil and potentially make your babies ill. With that in mind, knowing how long you can store your pumped milk and still maintain its quality is important.

For short-term storage (one to two days), mothers should keep the freshly-pumped milk in the refrigerator at 4 Celsius or below. For longer-term storage (up to 8 days) you can move the containers of pumped milk down into a deep freezer set at -15 Celsius or lower.

How To Store Breast Milk in Fridge

Pumping For Twins

Pumping for twins can be a time-consuming and exhausting process for any new mother. It’s essential to ensure that all of the breast milk you pump is stored correctly to maintain its quality. The following guide will explain how best to store breast milk in your fridge when pumping for twins.

First, it’s important to use BPA-free containers or bags specifically designed for storing breastmilk. Once the milk has been pumped, make sure it’s dated and labeled so you know exactly which container belongs to each twin and when it was stored. When transferring the containers or bags, fill them only up to three-quarters full as this allows room for expansion if the milk is frozen.

Can You Mix Breast Milk From Different Days?

Pumping for twins can be a challenge, as you have to pump and store twice the amount of breast milk compared to pumping for just one baby. But if you’re wondering whether it’s okay to mix breast milk from different days, the answer is yes.

Experts recommend that you keep your pumped breast milk in containers labeled with the date and time it was expressed. This will help you avoid confusion when preparing bottles for your babies. Additionally, research suggests that mixing two batches of freshly-expressed breastmilk in one bottle is safe and won’t decrease its nutritional value or reduce its immune benefits.

It’s important to note that all stored breastmilk should be used within 24 hours after thawing from frozen storage. This can help ensure optimal nutrition and prevent any possible bacteria growth in your baby’s bottles.

Can You Freeze Breast Milk?

Yes, you can freeze breast milk. Breast milk is a precious commodity and freezing it can help to preserve its nutritional benefits while providing convenience for busy moms who may not have time to pump fresh milk every day. The best way to store breastmilk is in containers specifically designed to freeze breastmilk. These containers allow the right amount of space between the frozen milk and the lid so that room is allowed for expansion when freezing.

When freezing breastmilk, it’s important to leave enough headroom in each container or bag as the liquid will expand during freezing. Breastmilk should also be labeled before being put away with the date and time expressed clearly. Frozen breastmilk can typically last up to 6 months when stored in a deep freezer set at 0°F (-18°C).

Can You Freeze Refrigerated Breast Milk?

Yes, you can freeze refrigerated breast milk. It’s a convenient way to safely store the extra breast milk you have left over that your baby isn’t able to consume immediately. Freezing helps preserve the nutritious benefits for your baby until needed and allows you to keep more of your expressed breast milk on hand for later use.

To properly freeze and store breast milk, make sure it is divided into 2-4 ounce portions in sealed containers or freezer bags before freezing. Write the date on the container or bag so you know how long it has been in the freezer. Breast milk stored in this manner will remain safe to drink for up to 6 months when stored at 0°F (-18°C). Breastmilk should not be refrozen once thawed, however; freshness is key!

When To Start Freezing Breast Milk

When it comes to breastfeeding, the decision to store breast milk for later use is a common one. The question of when to start freezing breast milk often arises among new mothers. Freezing breast milk can be a great way to provide an infant with nutrition at times when the mother is not able to nurse directly. It’s important, however, that women understand the proper steps involved in freezing their breast milk safely and effectively.

The basic rule when it comes to storing and freezing breast milk is that any expressed milk should be used within four hours of being expressed. If the mother wishes to store her expressed breast milk beyond this timeframe, she should transfer it into an appropriate container before refrigerating or freezing it. When transferring expressed breastmilk from one container to another, make sure that both containers are thoroughly washed first with hot soapy water and then rinsed well.

How Long Is Breast Milk Good for After Thawing?

Breast milk is widely regarded as the most convenient, nutritious, and natural food for babies. However, it’s important to understand how long breast milk can last after thawing to keep your baby safe. Thawed breast milk should be used within 24 hours of being stored in the refrigerator or up to eight days if placed in the freezer.

The best practice for storing and using breast milk is to only thaw what you plan to use immediately. Once thawed, don’t refreeze it. If you need more than one bottle of breast milk at a time, take out each bottle as needed so that you don’t waste any precious nutrients or put your baby at risk of food-borne illnesses due to spoilage.

Tips for Increasing Milk Supply

Breastfeeding can be a challenging experience for new mothers. Low milk supply is one of the biggest obstacles that nursing moms face. But, with a few simple tips and tricks, it is possible to increase your milk supply and give your baby the best nutrition possible.

First, it’s important to focus on hydration and nutrition. Eating regular meals and drinking plenty of fluids helps keep your body healthy, which in turn helps produce more milk. Additionally, eating nutrient-rich foods like oats or spinach can help boost your milk production even more. It’s also important not to skip meals – skipping meals decreases the amount of fat in breast milk and can lead to decreased milk supply over time.

Staying relaxed while breastfeeding is another great way to increase your milk supply as stress can interfere with hormone levels necessary for breastmilk production.

As you prepare for your twins’ arrival and learn about pumping, it’s also essential to consider the necessary items you’ll need to have on hand. One such item is receiving blankets. To find out how many you should have, take a look at our guide on How Many Receiving Blankets Do You Need?


Pumping for twins is no easy feat, but it can be done! Some challenges come with the task, but if you plan and take it slow, you can make it through. It’s important to remember that everyone’s journey with pumping is different. When it comes to breastfeeding twins, there’s no one-size-fits-all solution. So if you’re ever feeling overwhelmed or frustrated, take a deep breath and don’t give up!
