This article is not medical advice and we advise mothers to consult with a lactation consultant.


Understanding Breast Milk Production


Breast milk production has several phases, each with unique characteristics and benefits. The human body is truly amazing in its ability to adapt breast milk to accommodate your baby’s specific needs in their developmental stage. This also means we need to carefully consider when breast milk is expressed and how that relates to when it should be fed to your baby.


Stages of breast milk production


Colostrum is the first milk your body produces, typically starting during the last few weeks of pregnancy and continuing for a few days after birth. This thick, yellowish substance is rich in antibodies, vitamins, and minerals, providing nutrients and immune protection for your newborn.

Between 3 and 5 days after birth, your milk transitions from colostrum to a mixture called transitional milk. It becomes less thick and more abundant, containing higher levels of fat, lactose, and calories to meet your baby’s growing needs.

Around two weeks postpartum, your milk fully transitions to mature milk. This white or slightly bluish liquid perfectly balances nutrients, proteins, fats, and carbohydrates to support your baby’s growth and development.


When to Start Pumping Breast Milk


Many new mothers have the same question: when can they start pumping breast milk? As with most topics relating to breastfeeding and pumping, the answer varies depending on your individual circumstances and needs. However, some common scenarios may influence the decision on when to begin pumping.

Pumping during the early days after birth


Preterm or medically fragile babies


In the case your baby is born prematurely or has medical issues preventing them from breastfeeding, you may need to start with manual pumping or an electric pump immediately to establish and maintain your milk supply.

Pumping during these early days can help ensure that your baby receives essential nutrients and antibodies from your breast milk, even if they cannot latch on and nurse directly.


Establishing milk supply


For some mothers, pumping early can help stimulate milk production and increase supply to aid in milk flow. If you are struggling with a low milk supply or are concerned about your baby’s weight gain, consult a lactation consultant or healthcare professional. They can advise whether early pumping is appropriate for your situation.


Pumping after the first few weeks


Returning to work or school


If you plan to return to work or school and want to continue providing breast milk for your baby, it’s a good idea to try to pump a few weeks before your return. This will give you time to establish a routine, get used to your breast pump, and build up a freezer stash for your baby.

Your milk will not “mature” until 2-3 weeks postpartum, so pay close attention to when you start pumping and when that pumped milk is fed to your baby. It's always a good idea to use up the oldest milk first.


Building a freezer stash


Some mothers need to pump extra breast milk to create a “freezer stash” for future use. It's typically best practice to start freezing breast milk for your stash once your milk supply has stabilized, usually around four to six weeks postpartum when you are through the transitional milk period. This is because the transitional milk meets needs of your baby specific to the time it is produced.

Remember to follow safe storage guidelines and use non-toxic, eco-friendly storage solutions like Burrbaby’s glass containers.

Exclusive breast milk pumping from the start


Personal choice or medical reasons


You might exclusively pump breast milk from the start due to personal preference or medical reasons. If you do decide to pump exclusively, it’s a good idea to establish a regular pumping schedule to maintain your milk supply and meet your baby’s nutritional needs. 

Try to pump around the same time every day to mimic baby's feeding so you can maintain a good milk supply. As always consult with a healthcare professional or lactation consultant to determine the best time for you to begin pumping and to get tips on pumping.

There really is no perfect time to start pumping breast milk; the answer depends on your unique circumstances. The most important factor is to ensure your baby is getting the milk it needs when your body produces it, remembering your body uses a system to provide your infant with specific nutrients at certain times.


Tips for Successful Pumping


Choosing the Right Breast Pump


To ensure a smooth pumping experience, selecting the right type of breast pump for you is essential. There are two primary types: manual or electric breast pumps. Manual breast pumps are hand-operated and often portable, making them a cost-effective and convenient option for occasional use. However, they may require more physical effort and can be quite time-consuming.

Electric pumps, on the other hand, are a more efficient and hands-free experience. They come in various designs, including single and double pumps, and often have adjustable suction levels to match your comfort.


Features to Look For In Your Breast Pump


When choosing a breast pump, consider the following to find the best fit for your needs:

  1. Portability: If you plan to pump at work or on the go, look for a compact, lightweight, and battery-operated pump.
  2. Adjustable suction: Choose a pump with customizable suction levels to ensure comfort and efficiency.
  3. Noise level: Look for a quiet pump, especially if you plan to pump in public spaces or while your baby is asleep.
  4. Easy to clean: Pick a pump with a simple design and a closed system to reduce the risk of milk contamination and simplify the cleaning process.
  5. Cost: The cost of a breast pump is important. Try to balance the most important features to you with a price point that is affordable. Often times, insurance will provide a pump so check with your provider.


Creating a Comfortable Pumping Environment


A relaxing and comfortable environment plays a role in your overall experience pumping. Here are some tips for creating the perfect pumping atmosphere:

Relaxation Techniques


Stress can negatively impact your milk flow and overall enjoyment—practice relaxation techniques such as deep breathing, visualization, or calming music. You can also keep a photo or video of your baby nearby to help stimulate your milk let-down reflex.


Staying Hydrated and Nourished


Your hydration and nutrition are important aspects of your routine to keep your breast milk supply up. Keep a water bottle and healthy snacks within reach while pumping to ensure you’re meeting your body’s needs. Staying well-nourished and hydrated can also help you feel more relaxed and focused during your pumping sessions.

Pumping Schedule and Frequency


Another piece of the puzzle that can influence your comfort milk supply is your routine and pumping frequency. Here are some tips to help you find the perfect balance:


Mimic baby’s feeding patterns


One of the most effective ways to ensure an adequate milk supply is by mimicking your baby’s feeding patterns. Typically, newborns nurse 8 to 12 times in a 24-hour period. You can maintain a healthy milk supply and prevent engorgement by pumping as often as your baby would nurse. As your baby grows and starts to nurse less frequently, you can adjust your pumping schedule accordingly.


Prevent engorgement and maintain your  supply


Engorgement is an uncomfortable fullness in your breasts that can occur when milk is not removed regularly. To avoid engorgement and maintain your milk supply, it’s recommended to pump frequently, especially during the first few weeks. Experts recommend pumping at least 8 to 10 times daily for the first month. Then, as your milk supply becomes more established, you can gradually reduce the number of daily pumping sessions - again, in line with your baby's natural feeding patterns.

Remember that every mother’s experience is unique, and it’s crucial to listen to your body and adjust your pumping schedule as needed. Don’t hesitate to consult a lactation consultant or healthcare professional if you have concerns about your milk supply or pumping routine.


Storing and Handling Pumped Breast Milk


Once you've pumped your breast milk, now what? How you pump and store breast milk is an important component of the story to ensure that your baby receives all the benefits of your liquid gold. 


Safe storage guidelines:


Refrigeration and freezing


You can store milk in the refrigerator for up to 4 days at a temperature of 39°F (4°C) or lower. When freezing your milk, store it in the back of the freezer, where the temperature remains consistently cold. Frozen breast milk can last up to 6 months in a standard freezer or 12 months in a deep freezer. Always label your milk containers with the date of expression to help you keep track of the oldest milk in your stash.


Thawing and warming breast milk


When it’s time to use your frozen expressed breast milk, move it to the refrigerator for a slow thaw or place the container in a bowl of warm water for a quicker thaw. Avoid using a microwave to thaw or warm breast milk, as this can create hot spots that may burn your baby’s mouth and destroy some of the milk’s beneficial properties.

Gently swirl the milk to mix the fat that may have separated but avoid shaking the container vigorously. You don't want to create bubbles that could give your baby extra burps or gas.

Try to choose glass breast milk storage options


Although plastic breast milk storage bags are labeled as food-safe and free of certain harmful chemicals like BPA, there is always a risk that one of the current synthetic chemicals or additives in the plastic could leach into breast milk.

Additionally, microplastics can be shed from the plastic containers, especially during temperature fluctuations, such as when freezing and warming breast milk. These concerns cause many parents (us included) to consider alternatives to plastic for storing and feeding breast milk.

Conclusion: Finding the Right Time to Start Pumping for You and Your Baby


Determining the right time to pump breast milk is a personal decision that depends on your unique circumstances. Whether it's during the early days to establish your milk supply or waiting until a few weeks postpartum to prepare for returning to work or building a freezer stash, pumping allows you to do what works best for you and your baby. Remember that your body produces specific nutrients and an amount of milk that align with stages of your baby’s growth.

Breast milk production is influenced by hormonal changes and your baby’s demand, so it’s essential to be able to pump in a way that mimics your baby’s feeding patterns.
