Does Collecting Colostrum Help With Milk Supply?

Now, let’s get to the heart of the matter. When we ask, "does collecting colostrum help with milk supply," we have to look at it from two different angles: the physiological impact (the "plumbing") and the practical/behavioral impact (the "process").

The Physiological Reality

Physiologically speaking, hand-expressing colostrum during the final weeks of pregnancy does not typically "increase" the total volume of mature milk your body will eventually produce.

The production of milk is controlled by hormones. During pregnancy, high levels of progesterone actually keep your milk production in check. Once the placenta is delivered after birth, progesterone levels plummet, which signals the hormone prolactin to take over and tell your breasts to start producing larger quantities of milk. This is what people mean when they say their "milk came in."

Therefore, expressing colostrum at 37 weeks won't make your mature milk arrive in massive quantities on day one. However, some studies suggest that the act of stimulating the breasts prenatally may help the milk "come in" slightly sooner or more easily for some individuals, as the mammary tissue is already being "primed" for the job.

The Practical and Behavioral Impact

While the physiological boost might be subtle, the practical boost to your supply is significant. This is where collecting colostrum really shines.

Skill Acquisition: One of the biggest hurdles to a successful milk supply is a lack of confidence in hand expression. By practicing antenatal expression, you are learning exactly how your breasts work. If your baby has trouble latching in the first few days, you won't be panicking; you'll already know how to express those precious drops to feed them.
Early Stimulation: Frequent milk removal is the key to a healthy supply. By knowing how to hand express early, you can ensure your breasts are being stimulated from the very first hour after birth, even if the baby is sleepy. This early and frequent "demand" is what builds a robust "supply" for the weeks and months to come.
Avoiding Formula Supplementation: If a baby’s blood sugar drops or they need extra calories, hospitals often suggest formula. If you have a stash of colostrum ready, you can use that instead. This keeps the baby exclusively on human milk, which is beneficial for their gut health and keeps your body in the "breastfeeding loop."
Confidence and Stress Reduction: Stress is a known enemy of the let-down reflex. Parents who feel prepared and have a "backup" stash of colostrum often feel more relaxed. A relaxed parent usually has an easier time with milk ejection and establishing a supply.

So, while it might not change the biological "ceiling" of your production, it absolutely helps you reach your supply goals more effectively. In the world of lactation, every drop counts, and being prepared is half the battle.

Antenatal Colostrum Harvesting: What It Is and How It Works

Antenatal colostrum harvesting is the process of hand-expressing and storing colostrum during the final weeks of pregnancy—typically starting around week 36 or 37. It is a gentle, manual process. We do not recommend using electric or manual breast pumps for this purpose, as they can be too intense for the pregnancy breast and are often inefficient at capturing the thick, small amounts of colostrum produced at this stage.

Why Do People Do It?

Beyond the goal of supporting milk supply, there are specific medical reasons why a healthcare provider might suggest colostrum harvesting:

Maternal Diabetes: Babies born to mothers with gestational or pre-existing diabetes are at a higher risk of low blood sugar (hypoglycemia) after birth. Having colostrum on hand can stabilize their sugar levels without needing formula.
Planned Cesarean Section: Sometimes the transition to breastfeeding can be a bit slower after a C-section. Having colostrum ready ensures the baby is fed while the parent recovers.
Known Medical Conditions: If the baby is diagnosed with a condition like a cleft lip or palate, or a heart condition, they may have difficulty nursing initially.
Previous Low Supply: For parents who struggled with supply in the past, this practice provides a head start and a sense of empowerment.

Who Should Consider Colostrum Harvesting?

At Milky Mama, we believe that almost any healthy pregnant person can benefit from learning hand expression. However, representation matters, and we particularly encourage Black breastfeeding moms and those from underrepresented communities to explore this tool. Systemic barriers can sometimes lead to higher rates of medical intervention or formula supplementation in the hospital; having your own colostrum stored is a way to reclaim autonomy over your feeding journey.

Practical Scenarios

Consider the story of Maya. Maya had gestational diabetes and was worried about her baby being taken to the NICU for low blood sugar. She started harvesting colostrum at 37 weeks. By the time she went into labor, she had 15 tiny syringes of "liquid gold" frozen. When her baby was born and his blood sugar was slightly low, the nurses were able to give him Maya’s expressed colostrum. His levels stabilized, he stayed in the room with Maya, and they went on to have a beautiful breastfeeding relationship. This is the power of preparation!

Safety First: When to Start and When to Wait

Is it safe? This is the most important question. The reason we wait until 36 or 37 weeks is because nipple stimulation releases oxytocin. Oxytocin is the "love hormone" that helps with milk let-down, but it is also the hormone responsible for uterine contractions.

Guidelines for Safety:

Wait Until 36-37 Weeks: Do not start earlier unless explicitly cleared by your OB-GYN or midwife.
Keep it Short: Limit expression sessions to 5–10 minutes per breast, once or twice a day.
Listen to Your Body: If you feel any uterine tightening or contractions while expressing, stop immediately.
Consult Your Provider: This is especially critical if you have a history of preterm labor, a cervical cerclage (stitch), or any other high-risk pregnancy complications.

Step-by-Step Guide to Hand Expressing Colostrum

If you have been cleared by your provider and are ready to try, here is how you do it. Remember, it might take a few tries before you see anything. Be patient and gentle with yourself.

1. Set the Mood

Find a quiet, comfortable place where you won't be interrupted. Warmth helps the milk flow, so try expressing after a warm bath or shower, or apply a warm compress to your breasts for a few minutes.

2. Massage the Breast

Start with a gentle massage. Use your fingertips to make small circular motions from the top of the breast down toward the nipple. You can also gently stroke the breast toward the nipple. This mimics the "rooting" of a baby and helps trigger the hormones needed for milk movement.

3. The "C" Hold

Place your thumb above the nipple and your first two fingers below the nipple, forming a "C" shape. Your fingers should be about one to two inches back from the base of the nipple. You are looking to compress the milk ducts located under the areola, not the nipple itself.

4. Press, Compress, Release

This is the rhythmic motion of hand expression:

Press: Gently press your thumb and fingers back toward your chest wall.
Compress: Bring your thumb and fingers together. Do not slide them toward the nipple; keep them in the same spot.
Release: Relax your hand.

Repeat this rhythm: Press, Compress, Release. It may take a minute or two of rhythmic compression before a tiny, glistening drop of colostrum appears at the nipple.

5. Collect the Drops

Because colostrum is so thick and comes in such small amounts, you won't be filling a bottle. Use a clean, sterile 1mL or 3mL syringe to suck up the individual drops directly from the nipple. This ensures not a single drop is wasted.

6. Switch Sides

Once the flow slows down on one side, move to the other breast. You can go back and forth a couple of times during a 10-minute session.

Storing and Transporting Your "Liquid Gold"

Once you have collected your colostrum, you need to store it safely so it's ready for the big day.

Labeling: Label every syringe with your name, the date, and the time of collection.
Combining: You can collect colostrum throughout the day in the same syringe, but keep it in the refrigerator between sessions. At the end of the day, if the syringe is full (or if you are done for the day), put it in the freezer.
Freezing: Place the syringes in a clean, dated zip-lock bag in the back of the freezer (not the door, where temperatures fluctuate).
Transport to Hospital: When you go into labor, pack your frozen syringes in an insulated cooler bag with ice packs. Once you arrive at the hospital, ask the staff to store them in a medical freezer. Make sure your colostrum plan is noted in your birth preferences!

Bovine Colostrum Supplements vs. Human Colostrum

It is worth noting that there is currently a trend involving bovine (cow) colostrum supplements for adults. While these supplements are marketed for gut health and immune support in adults, they are not a substitute for human colostrum, nor is there evidence that taking them will increase your own milk supply.

Lactation is a "demand and supply" process. While your nutrition matters, your body makes milk based on hormonal triggers and the physical removal of milk from the breast. If you are looking to support your supply through nutrition, we recommend focusing on specialized lactation support products that are formulated specifically for breastfeeding parents.

For example, our Emergency Brownies are a fan favorite for a reason! They are designed to be a delicious way to incorporate supportive ingredients into your diet. If you prefer herbal support, our Lady Leche™ and Pumping Queen™ capsules are crafted by our IBCLC founder to support healthy lactation without the use of controversial herbs like fenugreek.

Real-World Scenario: Preparation Meets Peace of Mind

Let's look at another common scenario. Sarah was a second-time mom who had a very difficult time with her first baby. Her first child had a significant tongue-tie, and because Sarah didn't know how to hand express, the baby lost too much weight in the hospital, and Sarah felt pressured to use formula. She felt like she had "failed"—though we know there is no such thing as failing when you are doing your best to feed your baby!

With her second pregnancy, Sarah joined The Official Milky Mama Lactation Support Group on Facebook and learned about colostrum harvesting. She started practicing at 36 weeks. She only managed to collect about 5mL total over two weeks, but she learned the technique.

When her second baby was born and also had trouble latching, Sarah didn't panic. She calmly hand-expressed colostrum into a spoon and fed it to her baby. She felt empowered. That early stimulation helped her mature milk come in quickly, and she was able to navigate the early days with confidence. Sarah’s story shows that while the milk itself is valuable, the confidence is priceless.

Practical Tips for Boosting Supply After Birth

Whether you collected colostrum or not, the first few weeks after birth are the "window of opportunity" to establish a strong supply. Here is how you can support your body:

1. Skin-to-Skin Contact

Spend as much time as possible skin-to-skin with your baby. This releases oxytocin, which helps with milk flow and bonding. It also helps your baby stay warm and regulates their heart rate.

2. Nurse Frequently

In the beginning, babies should nurse at least 8 to 12 times in a 24-hour period. Don't wait for the baby to cry; look for early hunger cues like rooting, sucking on hands, or smacking lips.

3. Ensure a Good Latch

If nursing is painful, something is likely off with the latch. Seeking help early from a virtual lactation consultation can make a world of difference. A good latch ensures the baby is effectively removing milk, which tells your body to make more.

4. Hydration and Nutrition

Breastfeeding takes a lot of energy! Make sure you are eating enough calories and staying hydrated. Our lactation drink mixes like Pumpin Punch™ or Milky Melon™ are a delicious way to stay hydrated while supporting your journey.

5. Rest When You Can

We know "sleep when the baby sleeps" is easier said than done, but rest is vital for hormone regulation. Be gentle with yourself and ask for help with household chores so you can focus on your baby.

FAQ

1. Is colostrum harvesting safe for everyone? For most healthy pregnancies, colostrum harvesting after 36 or 37 weeks is considered safe. However, because nipple stimulation can cause uterine contractions, it is generally not recommended for those at risk of preterm labor, those with a history of cervical incompetence, or those experiencing pregnancy complications like placenta previa. Always check with your midwife or doctor before beginning.

2. How much colostrum should I expect to collect? Expect very small amounts! It is perfectly normal to only see a few tiny beads of milk or to collect only 0.5mL to 1mL in a session. Some people may not be able to collect anything at all during pregnancy, and that does not mean they won't have enough milk once the baby is born. The goal is as much about learning the technique as it is about the volume.

3. Can I use a breast pump to collect colostrum? We generally recommend hand expression over using a pump during pregnancy. Pumps are designed to move larger volumes of thinner, mature milk. Colostrum is very thick and sticky; it often gets lost in the pump parts and flanges. Hand expression allows you to collect every precious drop directly into a syringe. Additionally, hand expression is a vital skill to have once the baby arrives.

4. Will colostrum harvesting cause me to go into labor? While nipple stimulation releases oxytocin, which can cause mild uterine tightening (Braxton Hicks), there is no strong evidence that short sessions of hand expression in a healthy, full-term pregnancy will trigger active labor. However, if you experience regular or painful contractions while expressing, you should stop and contact your healthcare provider.

Conclusion

So, does collecting colostrum help with milk supply? While it may not biologically "force" your body to produce more mature milk, it is a powerful tool that sets you up for success. By practicing antenatal expression, you are gaining a vital skill, building your confidence, and providing your baby with a "liquid gold" insurance policy that can help avoid unnecessary formula supplementation and stabilize their health in those first few days.

Breastfeeding is a journey, and like any journey, it’s easier when you have a map and the right gear. Whether you are filling your first syringe with colostrum or simply reading up on what to expect, you are taking proactive steps to support your baby and yourself. You’re doing an amazing job, and your dedication is already making a difference.
