Introduction
As your due date approaches, it is completely normal to feel a surge of nesting energy. You are washing tiny onesies, organizing the nursery, and probably wondering how your body will handle the big task of feeding your new arrival. One of the most common questions we hear from expectant parents is: can you increase milk supply before birth? It is a natural concern, especially if you want to get a head start or feel anxious about having enough milk once the baby arrives.
At Milky Mama, we believe that education is the best way to feel empowered before your little one makes their debut. While you cannot technically increase the volume of mature milk you produce before your baby is born, there are very specific steps you can take to prepare your body and even harvest your first milk, known as colostrum. If you want personalized guidance before delivery, our Certified Lactation Consultant Breastfeeding Help page is a great place to start.
In this article, we will explore the science of how milk production starts. We will also discuss antenatal expression, which is the practice of collecting colostrum during the final weeks of pregnancy. You will learn about the health factors that influence your future supply and how to build a toolkit that supports your breastfeeding journey from day one.
Understanding the Biology of Pregnancy Milk
To answer whether you can increase milk supply before birth, we first have to look at how the body creates milk. The process of making milk is called lactogenesis, and it happens in stages. During pregnancy, your body goes through Stage I lactogenesis. This is when your breasts begin to develop the tissue needed for nursing and start producing colostrum.
Colostrum is often called "liquid gold." It is a thick, concentrated milk that is packed with antibodies, protein, and minerals. It is the perfect first food for a newborn because it acts like a natural vaccination and helps coat the baby’s digestive system. If you want to learn more about this early milk stage, our post on Does Colostrum Help Milk Supply? What to Know is a helpful next read.
The reason you do not produce large amounts of milk while pregnant is due to hormones. High levels of progesterone, which is the hormone that maintains pregnancy, actually keep your milk supply "on hold." It prevents the full "coming in" of mature milk. Only after the placenta is delivered does progesterone drop, signaling the body to begin Stage II lactogenesis, or the production of larger volumes of milk. Because of this biological "lock," you cannot force your body to produce mature milk before the baby is born.
What is Antenatal Expression?
While you cannot increase the volume of mature milk yet, you may be able to harvest colostrum. This is known as antenatal expression. This involves using your hands to gently express small amounts of colostrum in the final weeks of pregnancy. For many families, having a small stash of colostrum in the freezer provides incredible peace of mind.
Antenatal expression is usually recommended starting around the 36th or 37th week of pregnancy. We always recommend talking to your healthcare provider or a certified lactation consultant before you begin. If you want a step-by-step breakdown, our guide on Does Expressing Colostrum Increase Milk Supply? Key Facts walks through the process in more detail.
For most healthy pregnancies, mild contractions are not a concern. However, if you have a history of preterm labor or a high-risk pregnancy, your doctor might advise you to wait until after birth. If you get the green light, harvesting even a few milliliters of colostrum can be a great way to prepare for potential challenges, such as a baby who has trouble latching or low blood sugar at birth.
Benefits of Collecting Colostrum Early
Collecting colostrum before your baby arrives is not just about the milk itself. It is also about the skills you gain. When you practice hand expression, you become familiar with your own body. You learn where to apply pressure and how your breasts respond to touch. This confidence is invaluable during those first few days postpartum when everything feels new and sometimes overwhelming.
Having a small supply of colostrum stored in oral syringes can also prevent the early use of formula if a medical need arises. For example, if your baby is sleepy after birth or if your mature milk is slightly delayed, you can use your pre-collected colostrum to keep the baby nourished. This keeps the baby's tummy full of your specific antibodies while you work on establishing a latch.
- Provides a backup food source for the baby.
- Builds your confidence in handling your breasts.
- Reduces the stress of the first few days.
- Helps stabilize a newborn's blood sugar if needed.
Key Takeaway: You cannot increase the volume of mature milk before birth, but you can harvest colostrum to provide a safety net for your newborn.
How to Practice Hand Expression
Hand expression is a skill that takes a little practice. Unlike a breast pump, which uses suction, hand expression uses gentle compression to move milk out of the ducts. Most lactation experts recommend hand expression over pumping during pregnancy because it is gentler and often more effective at moving the thick, sticky colostrum.
To start, make sure your hands are clean and you are in a relaxed environment. You may find it helpful to apply a warm compress to your breasts for a few minutes first. Use a clean, wide-mouth container or a small oral syringe to catch the drops. Place your thumb and fingers in a "C" shape about an inch or two back from the base of your nipple.
Gently press back toward your chest wall, then compress your fingers together. Avoid sliding your fingers over the skin, as this can cause bruising. You are looking for a rhythmic "press and compress" motion. It may take several minutes before you see a single drop of colostrum. If you want more guidance on technique, the article about hand expressing milk is a helpful reference.
Factors That Influence Early Milk Supply
While you are still pregnant, it is a great time to look at your overall health. Certain medical conditions can affect how quickly your milk "comes in" after birth. If you know about these factors ahead of time, you can work with a lactation professional to create a proactive plan.
Conditions like Polycystic Ovary Syndrome (PCOS), gestational diabetes, or thyroid imbalances can sometimes cause a delay in milk production. This does not mean you cannot breastfeed. It simply means you might need extra support in those first few days. We often suggest that parents with these conditions focus heavily on skin-to-skin contact and frequent feeding or pumping immediately after delivery.
Previous breast surgeries, such as reductions or augmentations, can also play a role. The impact depends on how the surgery was performed and whether the milk ducts or nerves were affected. Discussing these details with an International Board Certified Lactation Consultant (IBCLC) before birth can help you set realistic expectations and find the right tools to support your journey.
Nutrition and Hydration During Pregnancy
Your body is doing incredible work right now. It is growing a human and preparing a complex nutritional system. While you do not need to eat specific "lactation foods" during pregnancy to increase your future supply, focusing on a nutrient-dense diet supports your overall wellness. This, in turn, helps your body recover faster after birth, which is essential for milk production.
Staying hydrated is one of the best things you can do. Water is a major component of breast milk, and keeping your fluid levels up helps your circulation and energy. If you find plain water boring, our Pumpin' Punch™ drink mix is a refreshing option to keep in your pantry for the early postpartum weeks.
Eating a balance of healthy fats, proteins, and complex carbohydrates provides the energy your body needs for the "marathon" of labor and the early days of nursing. We recommend having easy-to-grab snacks ready. Our Emergency Brownies are a favorite for a reason; they are delicious and contain ingredients like oats and flaxseed that many moms find helpful for supporting their supply once their milk has come in.
Setting Up Your Support System
One of the most effective ways to "increase" your success with milk supply is to build a support team before the baby arrives. Breastfeeding is a learned skill for both you and your baby. Having experts and loved ones in your corner can make all the difference when you hit a bump in the road.
We suggest finding a local or virtual lactation consultant during your third trimester. You can even book a prenatal consultation to discuss your history and goals. If you want a more structured learning option, our Breastfeeding 101 course is designed to help you feel more prepared before delivery.
Talk to your partner, friends, or family about how they can help. While they cannot nurse the baby, they can bring you water, prepare meals, and handle diaper changes so you can focus on skin-to-skin time. We have found that parents who have a clear plan for support often feel more confident and less stressed, which is great for the hormones that drive milk production.
Preparing Your Pumping Station
If you plan to pump, either exclusively or occasionally, the last few weeks of pregnancy are the perfect time to get familiar with your equipment. You do not need to start pumping yet, but you should know how the machine works. Read the manual, wash the parts, and make sure you have the correct flange size.
A flange is the plastic funnel that fits over your nipple. If it is too big or too small, pumping can be uncomfortable and less effective. Many lactation consultants can help you measure for the right fit before the baby is born. Setting up a dedicated "pumping station" with a comfortable chair, a phone charger, and a place for your water bottle will make those early sessions much easier.
We often recommend products like our Lady Leche™ herbal supplement for those who know they will want extra postpartum support. While you should wait until after birth to start herbal supplements, having them ready in your nursing basket can help you feel prepared.
The Importance of Skin-to-Skin Contact
Even if you cannot increase your milk supply before birth, you can prepare for the "Golden Hour." This is the first hour after your baby is born. If possible, ask your birth team to place the baby directly on your bare chest immediately after delivery. This skin-to-skin contact is a powerful biological trigger.
When your baby is skin-to-skin, your body releases a surge of oxytocin and prolactin. Prolactin is the hormone responsible for telling your breasts to make milk. This contact also helps regulate the baby’s temperature, heart rate, and blood sugar. It encourages the baby to follow their natural instincts to find the breast and latch for the first time.
If you want a deeper explanation of why this matters, our article on how skin-to-skin contact naturally boosts milk supply is worth bookmarking. If you have a Cesarean birth, you can still request skin-to-skin contact in the recovery room.
Managing Expectations and Stress
Stress is one of the biggest hurdles to a healthy milk supply. When you are stressed, your body produces cortisol, which can interfere with the let-down reflex. Preparing for birth and breastfeeding should feel empowering, not like another item on a stressful to-do list. It is okay to take things one day at a time.
Remember that every drop of colostrum you produce is valuable. If you try hand expression and only get a tiny bead of milk, you are doing a great job. That tiny bead is exactly what your baby’s marble-sized stomach needs in the beginning. You do not need to be producing ounces or bottles of milk in the first few days.
We want you to feel proud of what your body is doing. If you feel overwhelmed, take a breath and reach out for help. Whether it is through a Milky Mama support group or a professional consultant, you do not have to navigate this journey alone.

FAQ
Is it safe to pump while I am still pregnant?
In most healthy pregnancies, gentle breast stimulation or hand expression is safe after 36 weeks. However, because nipple stimulation can cause uterine contractions, you should always consult your healthcare provider before starting any form of milk expression while pregnant. If you have a history of preterm labor, your doctor may advise you to wait until after birth.
Why am I not leaking milk during my pregnancy?
Not leaking milk during pregnancy is completely normal and is not a sign of how much milk you will have after birth. Your body produces colostrum starting in the second trimester, but high levels of progesterone usually keep it from leaking out. Many successful breastfeeding parents never leak a single drop before their baby is born.
Can I take lactation supplements before my baby is born?
It is generally recommended to wait until after your baby is born to start herbal lactation supplements. During pregnancy, your hormones are already focused on maintaining the pregnancy and producing colostrum. Once the baby is here and your mature milk begins to come in, supplements can then be used to support and maintain your supply as needed.
Does the size of my breasts determine how much milk I will make?
No, breast size does not determine your milk production capacity. Breast size is mostly determined by fatty tissue, while milk is produced in the glandular tissue. People with all different breast sizes can produce a full and healthy milk supply for their babies. What matters most for supply is frequent milk removal and a good latch once the baby arrives.
