Worrying about milk supply is one of the most common stressors for new parents. You might find yourself constantly checking the ounces in a bottle or wondering if your baby is truly satisfied after a long nursing session. It is completely normal to feel this way, and we want you to know that you are doing an amazing job navigating these early days of parenthood. Understanding the "how" and "why" behind milk production can often ease that anxiety and give you a clear path forward.
At Milky Mama, we believe that education is the foundation of a successful breastfeeding journey. If you want a deeper overview of the basics, our Breastfeeding 101 course is a great place to start. One of the most critical components of that journey is a hormone called prolactin. This hormone is the primary driver of milk production, and while your body knows how to produce it, there are specific, evidence-based ways you can encourage those levels to stay high. In this post, we will explore practical strategies for naturally boosting your prolactin levels through frequent stimulation, proper timing, and supportive habits. Every drop counts, and by focusing on your body’s hormonal cues, you can feel more confident in your ability to nourish your baby.
Prolactin is often called the "milk-making hormone." It is produced by the pituitary gland in your brain. During pregnancy, your prolactin levels rise significantly to prepare your breasts for lactation. However, high levels of progesterone during pregnancy keep the milk from "coming in" fully until after the placenta is delivered. Once you give birth, progesterone drops, and prolactin takes center stage to kickstart milk production.
This process is divided into stages. The first stage, lactogenesis I, happens during pregnancy. The second stage, lactogenesis II, is when your milk volume increases significantly, usually two to five days after birth. For this transition to happen effectively, your body needs frequent signals that milk is being removed. Each time your baby nurses or you use a breast pump, your body sends a message to the brain to release more prolactin. This release then tells the milk-producing cells, called alveoli, to get to work.
It is helpful to think of prolactin as the "order" and your milk supply as the "delivery." If the orders stop coming in, the factory eventually slows down production. This is why consistent milk removal is the most powerful tool you have. If you want more guidance on the supply-and-demand side of feeding, our How to Help Low Milk Supply guide goes deeper into troubleshooting. While other hormones like oxytocin help with the let-down reflex (the release of milk), prolactin is what ensures there is milk there to be released in the first place.
Key Takeaway: Prolactin is the hormone responsible for creating milk. It relies on frequent signals from nursing or pumping to maintain high levels in the body.
Breastfeeding works on a supply and demand basis. This is a fundamental concept in lactation. The more milk that is removed from the breast, the more prolactin is released, and the more milk your body will make. If the breasts are allowed to stay full or engorged for long periods, a protein called "feedback inhibitor of lactation" (FIL) builds up. This protein tells your body to slow down because the "storage tanks" are full.
To keep prolactin levels high, you should aim to remove milk 8 to 12 times in a 24-hour period. This is especially vital in the first few weeks as you establish your supply. Responsive breastfeeding—meaning you feed your baby whenever they show hunger cues rather than following a strict clock—is the most natural way to achieve this. Early hunger cues include rooting, sucking on hands, or smacking lips.
If you are exclusively pumping or your baby is not yet nursing efficiently, the same rules apply. You must mimic the frequency of a nursing newborn.
One of the most effective ways to boost your prolactin levels is to focus on the middle of the night. Prolactin follows a circadian rhythm, meaning its levels fluctuate throughout the day and night. For most lactating parents, prolactin levels are naturally at their highest between 2:00 AM and 6:00 AM. If you want a closer look at the science behind this, Does Pumping at Night Increase Milk Supply? explains why this window matters so much.
While the idea of extra sleep is tempting, skipping nighttime sessions can lead to a drop in overall daily supply. By nursing or pumping during these early morning hours, you are taking advantage of your body's natural hormonal peak. This sends a very strong signal to your brain to keep production high for the following day.
If your baby is sleeping longer stretches, you might consider a "dream feed" or a quick pumping session before you head to bed yourself. However, for those struggling with supply, at least one session between 2:00 AM and 5:00 AM is often recommended by lactation professionals to keep those prolactin receptors active.
What to do next:
Your body is designed to respond to your baby’s physical presence. Skin-to-skin contact, often called "Kangaroo Care," is not just for the early days in the hospital. It is a powerful tool for hormonal regulation throughout your entire breastfeeding journey. When you hold your baby skin-to-skin, your body releases a surge of oxytocin, which helps with milk flow, but it also supports the continued release of prolactin.
The smell of your baby, the sound of their sounds, and even just looking at them can trigger a hormonal response. If you are pumping away from your baby, many parents find that looking at a video or smelling a piece of the baby’s clothing can help stimulate a better let-down and support the hormonal cycle.
Physical closeness helps reduce stress. High levels of the stress hormone cortisol can sometimes interfere with the let-down reflex. While stress doesn't necessarily "stop" prolactin from being made, it can make it much harder for the milk to leave the breast. When milk stays in the breast, FIL levels rise, and your body receives the signal to slow down production. Creating a calm environment for feeding or pumping is a simple but effective way to protect your supply.
Key Takeaway: Physical closeness with your baby triggers the hormones needed for milk production and release. Use skin-to-skin contact daily to support your supply.
If you are looking for a more structured way to increase the signals sent to your brain, certain pumping techniques can help. One popular method is "power pumping." This technique is designed to mimic a baby going through a "cluster feed"—a period where a baby wants to nurse very frequently for a few hours to tell the body to increase production. Our Increasing Your Milk Supply with Power Pumping guide walks through that approach in more detail.
To power pump, you replace one regular pumping session with a one-hour block of intermittent pumping:
This repeated "on-and-off" stimulation sends multiple signals to the pituitary gland in a short period, which can lead to an increase in prolactin release. Most parents see an increase in supply after three to four days of consistent power pumping once a day.
Another strategy is double pumping. Using a high-quality electric breast pump on both sides at once has been shown to be more effective at removing milk and stimulating prolactin than pumping one side at a time. It drains the breasts more thoroughly, which is the key to telling your body to make more.
While stimulation is the primary way to increase prolactin, your overall wellness plays a supporting role. Your body needs adequate energy and nutrients to maintain the complex process of lactation. Staying hydrated and eating a balanced diet is essential. Certain ingredients, known as galactagogues, have been used for generations to support milk supply and may help support the body’s natural processes.
Oats, flaxseed, and brewer's yeast are common ingredients found in lactation support products because they are nutrient-dense and supportive of nursing parents. If you want a snack-based option, explore our lactation snacks collection. For an everyday supplement option, our lactation supplements collection can be a helpful next step. At Milky Mama, we incorporate these ingredients into our most popular treats, including Emergency Lactation Brownies, for parents looking for a delicious way to support their supply while juggling the demands of a new baby.
In addition to treats, herbal supplements can offer concentrated support. Our Pumping Queen supplement is formulated to support the pumping journey alongside frequent milk removal. It is important to remember that supplements work best when paired with frequent milk removal. They are a tool to support your hard work, not a replacement for it.
Action steps for nourishment:
While the tips above help many parents, sometimes there are underlying medical reasons why prolactin levels might be low. In rare cases, conditions like Sheehan’s syndrome (pituitary damage during childbirth) or certain hormonal imbalances can affect milk production. If you have tried increasing your frequency of milk removal and are still seeing very little milk, it is time to seek professional help.
An International Board Certified Lactation Consultant (IBCLC) can help you evaluate your baby's latch and milk transfer. They can also work with you to create a personalized plan. Milky Mama’s Certified Lactation Consultant Breastfeeding Help page is designed for that kind of support. If a medical issue is suspected, they can coordinate with your primary healthcare provider to check your blood levels.
In some clinical settings, healthcare providers may discuss medications or specific hormonal therapies if there is a diagnosed prolactin deficiency. This is typically reserved for cases where physical stimulation alone is not enough, such as with parents of premature infants who must rely entirely on pumping. Always consult with a medical professional before starting any new medication or high-potency herbal regimen.
Key Takeaway: If frequent milk removal and supportive habits aren't helping, an IBCLC can provide the clinical expertise needed to troubleshoot supply issues.
Increasing your prolactin levels is a journey of consistency and connection. By focusing on frequent milk removal, prioritizing those high-prolactin nighttime sessions, and spending time skin-to-skin with your baby, you are giving your body the best possible signals to produce milk. Remember that every body is unique, and progress may take a few days to become visible. Be patient with yourself and your body as you work through these steps.

Yes, you can increase prolactin levels through frequent and effective breast pumping or hand expression. Using a high-quality electric pump 8 to 12 times a day mimics the stimulation a nursing baby would provide. Focusing on nighttime pumping sessions is especially effective for boosting these hormone levels when they are naturally at their peak.
While no food is a "magic" cure, certain nutrient-dense ingredients like oats, brewer's yeast, and flaxseed are traditionally used to support lactation. These ingredients provide essential minerals and B-vitamins that support overall maternal wellness and energy levels. We include many of these in our snacks to help parents maintain a nourishing diet while breastfeeding.
Most parents begin to see a noticeable increase in milk supply within 48 to 72 hours of increasing the frequency of milk removal. However, it can sometimes take up to a week of consistent "demand"—such as through power pumping or more frequent nursing—for the body to fully adjust its production levels. Consistency is the most important factor during this window.
Stress doesn't necessarily stop the production of prolactin, but it can significantly inhibit the release of oxytocin, which is needed for the milk let-down reflex. If the milk cannot be released effectively, the breast stays full, which eventually signals the body to slow down prolactin production. This is why creating a relaxing environment and practicing skin-to-skin contact is so beneficial for supply.
