Introduction

It is completely normal to feel a mix of excitement and a little bit of "can I really do this?" as your due date approaches. One of the most common questions we hear from expectant parents is how to increase breast milk supply before giving birth. You want to make sure your body is ready to nourish your little one from the very first moment. While your mature milk won't actually "come in" until after your baby is born, there are many proactive steps you can take during pregnancy to set the stage for a robust supply.

At Milky Mama, we believe that preparation is the key to a confident breastfeeding journey. We understand that while breastfeeding is natural, it is also a learned skill for both you and your baby. This post will cover the science of how your body prepares for lactation, the benefits of prenatal hand expression, and the lifestyle choices you can make now to support your future milk production. Our goal is to empower you with the knowledge and tools you need to feel ready for day one.

Understanding how your body works and what you can do during the third trimester can significantly reduce stress once the baby arrives. By focusing on education, health optimization, and a few specialized techniques, you can build a strong foundation for your breastfeeding relationship. If you want more personalized guidance, our breastfeeding help page is a great place to start.

Understanding the Biology of Prenatal Milk Production

Before you can focus on increasing your supply, it is helpful to understand how your breasts prepare for feeding during pregnancy. This process is called lactogenesis, which is the clinical term for the initiation of milk secretion. It happens in stages, and the first stage actually begins long before you head to the delivery room.

Stage One: Lactogenesis I

Around the midpoint of your pregnancy, usually between weeks 16 and 20, your body begins Lactogenesis I. During this phase, your mammary tissue develops, and your breasts start producing colostrum. Colostrum is often called "liquid gold" because it is a thick, concentrated first milk that is packed with antibodies and nutrients.

Even if you do not see any leaking or changes in your breast size, your body is working behind the scenes to create this vital first food. During pregnancy, high levels of progesterone—a hormone produced by the placenta—keep your full milk supply "turned off." This prevents you from producing large volumes of mature milk until the baby is actually here.

Stage Two: The Transition After Birth

Lactogenesis II is the stage where your milk "comes in." This typically happens two to five days after birth. It is triggered by the delivery of the placenta, which causes progesterone levels to drop sharply. This hormonal shift signals your body to increase milk volume and transition from colostrum to mature milk.

Because the "switch" for a full supply is triggered by the birth itself, you cannot technically increase your volume of mature milk while you are still pregnant. However, you can influence how quickly and effectively your body responds to your baby's needs after delivery.

Key Takeaway: You already have milk! Your body begins making colostrum midway through pregnancy, but high progesterone levels prevent a large volume of milk from forming until after the placenta is delivered.

The Role of Prenatal Hand Expression

The most direct way to interact with your milk supply before birth is through prenatal hand expression. Hand expression is a technique where you use your hands to gently compress the breast tissue to express colostrum.

Many lactation experts recommend starting this practice around week 36 or 37 of pregnancy, provided you have a healthy, low-risk pregnancy. Always consult with your healthcare provider before starting, as nipple stimulation can occasionally trigger uterine contractions.

Why Harvest Colostrum?

Harvesting colostrum before birth can be incredibly beneficial. It allows you to collect and freeze small amounts of "liquid gold" that can be used if your baby needs a supplement in the early days. This is especially helpful if you have gestational diabetes or if your baby is at risk for low blood sugar after birth.

Beyond the collection of milk, the act of hand expression helps you become familiar with your breast tissue. You learn where your milk ducts are and how your body responds to touch. If you want more guidance on lactation questions like this, Milky Mama’s breastfeeding help page can help you connect with support.

How to Practice Hand Expression

Wash your hands: Always start with clean hands and a sterile container if you plan to save the milk.
Massage: Gently massage your breasts or apply a warm compress for a few minutes to encourage flow.
The "C" Hold: Place your thumb and fingers in a "C" shape about an inch or two back from the base of the nipple.
Press and Release: Gently press back toward your chest wall, then compress your fingers together. Avoid sliding your fingers over the skin or pulling on the nipple.
Rotate: Move your hand to different positions around the breast to reach different milk ducts.

What to do next:

Discuss prenatal hand expression with your OB-GYN or midwife.
Purchase sterile oral syringes (1ml or 3ml) to collect and freeze colostrum.
Practice for 5–10 minutes once or twice a day starting at 37 weeks.

Optimizing Your Health for Future Supply

While you wait for your baby's arrival, focusing on your overall wellness can have a positive impact on your future lactation. Certain medical conditions and lifestyle factors can influence how quickly your milk comes in.

Managing Medical Conditions

If you have a history of Polycystic Ovary Syndrome (PCOS), diabetes, or thyroid issues, it is important to work closely with your medical team. These conditions can sometimes cause a delay in Lactogenesis II. Keeping your blood sugar well-managed during the third trimester is one of the best ways to support your future milk supply.

If you have had breast surgery in the past, such as an augmentation or reduction, this is the time to speak with an International Board Certified Lactation Consultant (IBCLC). An IBCLC is a healthcare professional who specializes in the clinical management of breastfeeding. They can help you assess your breast tissue and create a plan to maximize your supply.

Nutrition and Hydration

Eating a balanced diet now helps your body build the energy stores needed for the "work" of making milk. Focus on nutrient-dense foods like leafy greens, lean proteins, and healthy fats. Some parents choose to incorporate specific ingredients early, such as oats and flaxseed, which are traditional galactagogues. A galactagogue is a substance that may help increase milk supply.

Staying hydrated is equally important. While drinking excess water won't "over-produce" milk, being dehydrated can certainly hinder your body’s functions. We often recommend having a hydration plan in place, and our lactation drink mixes are a helpful postpartum option when you're ready for that next step.

Rest and Stress Management

High levels of stress hormones, like cortisol, can interfere with the hormones needed for milk production. While it is easier said than done during the final weeks of pregnancy, prioritizing rest is vital. Stress can delay the onset of mature milk, so finding ways to relax—whether through prenatal yoga, meditation, or reading—can actually support your future supply.

Building Your Support Village

Breastfeeding is a journey that is much easier to navigate with a team behind you. One of the best things you can do to "increase" your chances of a high supply is to ensure you have support ready to go the moment you deliver.

Finding an IBCLC

Don't wait until you are struggling with a latch to find a lactation consultant. Research local IBCLCs or check if your insurance covers virtual consultations. Knowing exactly who to call if you have questions on day three can prevent small issues from becoming big supply problems. We offer virtual lactation consultations that can be booked ahead of time to give you peace of mind.

Educating Your Partner and Family

Your support system needs to understand how breastfeeding works. If your partner knows that frequent nursing is normal and necessary for building supply, they can encourage you during those long cluster-feeding nights. Cluster feeding is when a baby wants to nurse very frequently (sometimes every hour) over a period of several hours. This is a natural way babies "order" more milk for the next day, and our article on cluster feeding and milk supply explains it in more detail.

Setting Up a Nursing Station

Prepare a space in your home where you can comfortably nurse or pump. Having everything you need within arm's reach will help you stay relaxed.

Comfortable seating: A chair with good back and arm support.
Hydration and snacks: Keep water and nourishing snacks nearby.
Phone charger: You will likely spend a lot of time in this spot!
Breastfeeding supplies: Burp cloths, nursing pads, and nipple balm.

Key Takeaway: Education is the foundation of supply. The more you know about what is "normal" (like cluster feeding and the small size of a newborn's stomach), the less likely you are to worry about low supply unnecessarily.

Preparing Your Gear and Supplies

If you plan to pump at any point, getting your gear ready before the baby arrives is a huge stress-reducer. While you shouldn't start pumping to build a supply while pregnant (unless directed by a medical professional), you should be familiar with your machine.

Check Your Breast Pump

Most insurance plans in the US cover a breast pump. Order yours early so you can open the box, wash the parts, and learn how to assemble it. You don't need to turn it on yet, but knowing how it works will save you from a frustrated "middle of the night" assembly session later.

Measure Your Flanges

The flange is the funnel-shaped part of the pump that fits over your nipple. Using the wrong size flange can lead to pain and decreased milk removal, which eventually leads to a lower supply. Since your nipple size can change during pregnancy and again after birth, it is a good idea to have a ruler or a sizing tool ready. If the flange is too small or too large, it won't effectively signal your body to make more milk.

Stocking the Pantry

The early weeks of breastfeeding require a lot of calories. Many parents find it helpful to stock up on lactation-supportive snacks before the baby arrives. For example, our Emergency Brownies are a favorite for a reason—they are delicious and made with ingredients like oats and brewer's yeast to support supply. Having these on hand means you won't have to worry about baking or shopping when you are in the thick of newborn life.

The "Golden Hour" and Early Feeding Plans

The first hour after birth, often called the "Golden Hour," is a critical time for establishing your milk supply. When you are creating your birth plan, include your preferences for early feeding.

Skin-to-Skin Contact

Spending as much time as possible skin-to-skin with your baby immediately after birth and in the following days is one of the most effective ways to boost supply. This contact triggers the release of oxytocin, the "love hormone," which is responsible for the let-down reflex. The let-down reflex is the process where your body releases milk from the ducts so it can flow to the baby.

Feeding on Demand

In the first few days, your baby's stomach is only the size of a marble. They need to eat frequently—usually 8 to 12 times in a 24-hour period. Instead of following a strict clock schedule, watch for your baby’s hunger cues (like rooting, sucking on hands, or smacking lips). Feeding on demand signals your body to produce exactly what your baby needs. The more often the breast is emptied, the more milk your body will create.

Avoiding Early Supplementation (Unless Medically Necessary)

If your goal is to exclusively breastfeed, try to avoid giving formula or water in the first few days unless there is a medical reason. Your body needs the stimulation from the baby's nursing to understand how much milk to make. If a bottle replaces a nursing session, your body doesn't get the message to produce that milk, which can lead to a lower supply over time.

Managing Expectations: What is "Normal" Supply?

One of the biggest hurdles to a successful breastfeeding journey is the fear that you aren't making enough. In the first few days, you will only produce small amounts of colostrum. This is normal! Your baby does not need ounces of milk yet; they only need teaspoons.

Signs the Baby is Getting Enough

Since you can't see how much milk is being transferred during nursing, you can look for these signs of success:

Wet and dirty diapers: Your pediatrician will give you a chart, but generally, you want to see an increasing number of wet diapers each day until day five.
Active swallowing: You should be able to hear or see your baby swallowing during a feed.
Baby is satisfied: While newborns are often fussy, a baby who pulls off the breast and seems relaxed for a period of time is likely getting what they need.
Weight gain: It is normal for babies to lose a small amount of weight in the first few days, but they should be back to their birth weight by two weeks.

If you are ever concerned, reach out to your pediatrician or an IBCLC. They can perform a "weighted feed," where the baby is weighed before and after nursing to see exactly how much milk they consumed.

Supporting Your Supply with Supplements

Many parents wonder if they should start taking lactation supplements before birth. Generally, we recommend waiting until after your baby is born to see how your natural supply develops. However, having a plan for which supplements you might use can be very helpful.

At Milky Mama, we offer a variety of herbal supplements designed to support different needs. For example, Lady Leche™ is crafted to support supply and provide a nutritional boost. If you find you need support with milk flow later on, Pumping Queen™ or Dairy Duchess™ may be helpful additions to your routine. You can also browse our lactation supplements collection to see the full range.

Always remember that supplements work best when paired with frequent milk removal (nursing or pumping). They are "helpers" to the supply-and-demand system, not a replacement for it.

Key Takeaway: Your body is a remarkable system. By focusing on frequent nursing, skin-to-skin contact, and proper nutrition, you are doing the best work possible to ensure a healthy milk supply.

Action Plan for the Third Trimester

To make this feel less overwhelming, here is a simple checklist of what to do in your final weeks of pregnancy:

Educate: Take a breastfeeding class or read a book by a certified expert.
Consult: Talk to your doctor about prenatal hand expression.
Collect: If cleared, start hand expressing and saving colostrum at 37 weeks.
Connect: Find a local or virtual IBCLC and save their contact info.
Prep: Order your pump, check your flange size, and stock your pantry with nourishing snacks like Emergency Brownies.
Plan: Include "Golden Hour" and skin-to-skin time in your birth preferences.

Conclusion

Preparing to feed your baby is one of the most loving things you can do during your pregnancy. While you cannot technically "increase" a mature milk supply before giving birth, the steps you take now—from prenatal hand expression to building a support network—will make a world of difference once your baby arrives. Remember that every drop of colostrum is valuable and every bit of knowledge you gain is a tool in your pocket.

Breastfeeding is a journey with ups and downs, but you don't have to do it alone. Trust your body, stay hydrated, and give yourself grace as you and your baby learn this new skill together. You're doing an amazing job.

"Breastfeeding is a beautiful, sometimes challenging, but ultimately rewarding experience. Your body was literally created to feed your baby, and with the right support, you can reach your goals."

FAQ

Can I start pumping before I give birth to increase my supply?

No, it is generally not recommended to use a breast pump before giving birth unless specifically instructed by your doctor. Nipple stimulation can release oxytocin, which may trigger uterine contractions and lead to preterm labor. If you want to prepare your breasts, focus on gentle hand expression after 37 weeks with your provider's approval.

Does the size of my breasts during pregnancy predict my milk supply?

Breast size is not an indicator of how much milk you will produce. Milk production depends on the amount of functional glandular tissue and the "supply and demand" signal created by your baby’s nursing. People with all different breast sizes can successfully produce a full milk supply.

What foods should I eat during pregnancy to help my milk come in?

Focus on a balanced, nutrient-dense diet rich in proteins, healthy fats, and complex carbohydrates. Foods like oats, flaxseeds, and leafy greens are excellent for overall health and are often used to support lactation postpartum. Staying well-hydrated is also essential for your body's overall function and future milk production.
