As you approach your due date, your nesting instinct might be in high gear. You are likely folding tiny onesies, setting up the nursery, and wondering what those first few days with your baby will really be like. For many expectant parents, one of the biggest questions on their mind is milk supply. You might find yourself searching for ways to get a head start or wondering how to increase milk supply before birth so you can feel confident from day one.
At Milky Mama, we know that while breastfeeding is a natural process, it is also a learned skill that requires support and preparation. If you want a deeper foundation before baby arrives, our Breastfeeding 101 course is a helpful place to start. The good news is that your body is already hard at work long before your baby arrives. By understanding how lactation begins and taking a few proactive steps during your third trimester, you can set a strong foundation for your feeding journey.
This guide will walk you through the science of prenatal milk production, the practice of colostrum harvesting, and the lifestyle choices that can support your supply before you even head to the hospital. If you want personalized guidance along the way, our breastfeeding help page is there for extra support. Our goal is to empower you with clinical expertise and practical tips to help you feel ready for your baby’s first latch.
To understand how to support your supply before birth, it helps to know how your breasts function during pregnancy. Milk production happens in stages, and the first stage actually begins months before you give birth.
Around the midpoint of your pregnancy, your body begins Lactogenesis I. This is the process where your breasts start making colostrum, often called "liquid gold." Colostrum is a thick, concentrated milk that is packed with antibodies, protein, and minerals. It is specifically designed to be the perfect first food for a newborn’s tiny stomach. Even if you don’t see any leaking, your body is producing this milk and storing it in the milk-making tissues called alveoli.
The transition to a higher volume of mature milk—what people usually mean when they say their "milk came in"—does not happen until after birth. This transition, known as Lactogenesis II, is triggered by the delivery of the placenta. When the placenta leaves your body, your progesterone levels drop sharply, which signals your brain to release high amounts of prolactin. Prolactin is the hormone responsible for making milk.
Because this second stage is triggered by birth, you cannot technically force your "mature" milk to come in while you are still pregnant. However, you can take steps to ensure your body is primed and ready for this transition to happen as efficiently as possible.
Key Takeaway: Your body is already making colostrum during the second and third trimesters. While you can't increase mature milk volume until after birth, you can practice techniques to access the colostrum you already have.
It is a common misconception that you need to "build up a supply" of mature milk before the baby arrives. In reality, milk supply works on a system of supply and demand. Your body won't start making large quantities of milk until there is a baby (or a pump) removing milk from the breast.
However, there are three main ways you can "increase" your success and support your supply prenatally:
One of the most effective ways to feel proactive about your supply is colostrum harvesting. This involves using your hands to gently express the colostrum that your body is already making.
Most lactation consultants recommend waiting until you are at least 37 weeks pregnant to begin hand expression. This is because nipple stimulation can sometimes cause uterine contractions. While this is generally not a concern for a healthy, full-term pregnancy, you should always consult with your healthcare provider or a certified lactation consultant before starting.
Practicing hand expression before birth does more than just give you a "stash." It helps you become familiar with your breast anatomy. Research suggests that parents who practice prenatal hand expression often feel more confident and may have an easier time establishing their milk supply in the first few days after birth.
What you eat and drink during your third trimester can play a role in how your body prepares for lactation. While there is no "magic food" that will cause an instant oversupply while you are still pregnant, focusing on specific nutrients can support the hormones involved in milk production.
Milk is largely made of water. If you are dehydrated, your body may struggle to maintain optimal fluid balance for milk production once the baby is born. During the final weeks of pregnancy, focus on consistent hydration. Our Lactation LeMOOnade is a refreshing way to stay hydrated while also getting the benefit of lactation-supporting ingredients. These drinks are designed to provide hydration plus the nutrients your body needs to support the transition to breastfeeding.
Oats and flaxseeds are traditional staples in a lactation-friendly diet. They provide slow-burning energy and B vitamins. You can start incorporating these into your diet now. Our Emergency Lactation Brownies are a favorite for many moms-to-be. They are packed with ingredients like oats and flax, making them a delicious way to prep your body for the demands of the fourth trimester.
The quality of your milk can be influenced by your intake of healthy fats. Omega-3 fatty acids, found in walnuts, chia seeds, and certain fish, are essential for baby’s brain development and help support your own hormonal health.
Takeaway: Focus on a nutrient-dense diet and high-quality hydration in your final weeks. This ensures your body has the "building blocks" ready for when the real work of breastfeeding begins.
For some parents, certain medical conditions can make it a bit harder for milk to "come in" or for the supply to reach its full potential. Identifying these factors before birth allows you to create a proactive plan with your medical team.
Hormonal imbalances associated with PCOS or insulin resistance can sometimes delay Lactogenesis II. This means it might take a few extra days for your milk volume to increase. If you have these conditions, prenatal hand expression is often highly recommended. It ensures you have colostrum ready if the baby needs a supplement, and it signals your breasts to begin working early.
If you have had a breast reduction, augmentation, or any other chest surgery, some of the milk ducts or nerves may have been affected. While many people with a history of surgery go on to have a full milk supply, it is helpful to discuss this with an International Board Certified Lactation Consultant (IBCLC) before you deliver. They can help you monitor the baby’s intake and weight gain closely in the early days.
An underactive thyroid can interfere with the hormones needed for milk production. If you are on thyroid medication, ensure your levels are checked during your third trimester and again shortly after birth.
Breastfeeding is a team effort. One of the best ways to "increase" your supply is to ensure nothing gets in the way of those first few critical days of nursing.
Don't wait until you are sore or worried about supply to find a lactation consultant. Research consultants in your area or look into virtual support options. We offer virtual lactation consultations that allow you to get professional, certified help from the comfort of your home. Having a professional you can text or call on day three can make a world of difference.
The events of your birth can impact how quickly your milk comes in. If possible, include the following in your birth plan to support early milk supply:
The most important thing you can learn before birth is how milk supply actually works. Many parents worry they have a low supply because they don't understand normal newborn behavior.
Once your milk "comes in" (Lactogenesis II), your body switches from being hormone-driven to being removal-driven. This means the more milk you remove from the breast, the more milk your body will make. If you skip a feeding or a pumping session, your body receives a signal to slow down production.
Understanding that newborns need to eat 8 to 12 times in a 24-hour period is crucial. It is common for babies to "cluster feed," which means they want to eat every hour for several hours. This is not a sign that you don't have enough milk; it is the baby’s way of "placing an order" for more milk the next day.
If you want to understand the mechanics of pumping and feeding in those early days, our Breastfeeding and Pumping guide is a useful next read.
Many parents look into herbal supplements prenatally to help "boost" their system. While you generally don't need to start lactation supplements before the baby is born, it can be helpful to have them on hand so you aren't rushing to order them during the postpartum haze.
Our herbal lactation supplements, such as Lady Leche or Pumping Queen, are designed to support milk production and flow. Lady Leche is often a great starting point because it contains Moringa, which is a nutrient-dense galactagogue that supports milk supply.

The final step in increasing your supply before birth is creating a physical environment that encourages frequent feeding and relaxation. Stress and pain can inhibit oxytocin, which can make it harder for your milk to let down.
Create a "nursing nest" in the area of your home where you plan to spend the most time. Stock it with:
While it’s hard to "sleep for the future," being well-rested when you go into labor can help your body recover faster, which in turn helps your milk supply. In your final weeks, prioritize rest and delegate household tasks to others. If friends ask how they can help, ask them to bring a meal or help with laundry so you can focus entirely on your recovery and feeding your baby.
Preparing for breastfeeding is about more than just your body; it’s about your mindset and your environment. While you cannot technically increase the volume of your mature milk before birth, you can absolutely influence the success of your journey.
By practicing hand expression, focusing on nutrient-dense foods, and educating yourself on the mechanics of lactation, you are giving yourself and your baby a significant advantage. Remember that every body is different, and the "arrival" of milk can vary from person to person. If things don't go perfectly in those first few days, know that support is available.
Key Takeaway: Success in breastfeeding starts with confidence and preparation. Collect your colostrum, eat well, and set up your support system now so you can focus on bonding later.
The journey to a healthy milk supply starts long before your baby takes their first breath. By understanding the stages of lactation and taking proactive steps like colostrum harvesting and nutritional preparation, you are setting the stage for a positive experience. Focus on your wellness, trust your body’s ability to nourish, and don't hesitate to reach out for professional help if you feel uncertain.

It is generally not recommended to use a breast pump before birth unless specifically instructed by a medical professional. Pumping is more vigorous than hand expression and may increase the risk of inducing labor. Hand expression is the preferred method for colostrum harvesting in the final weeks of pregnancy.
Not necessarily. Leaking (or a lack of leaking) during pregnancy is not a reliable indicator of your future milk supply. Some people leak significantly and have a standard supply, while others never leak a drop and go on to have an oversupply. Both are completely normal variations of how the body prepares for birth.
Focusing on complex carbohydrates like oats, healthy fats, and consistent hydration is highly beneficial. While these foods won't "force" your milk to come in earlier, they provide the nutritional foundation your body needs for a smooth transition to Lactogenesis II. Staying hydrated with electrolyte-rich drinks can also help maintain the fluid balance necessary for milk production.
If you try hand expression and nothing comes out, do not panic! This is very common and does not mean you won't be able to breastfeed. Many people find it difficult to express colostrum without the hormonal surge that happens after birth. Your body is still making it, and your baby will be much more efficient at removing it than your hands are.
