If you are currently preparing for your baby’s arrival, you are likely already thinking about how to provide the best nutrition possible. Many expectant parents wonder what they can do while pregnant to increase milk supply before their little one even arrives. It is natural to want to be proactive and ensure you have everything your baby needs from day one.
At Milky Mama, we know that the transition into breastfeeding can feel overwhelming, but preparation is the key to confidence. While your body is already hard at work preparing to nourish your baby, there are specific steps you can take now to set yourself up for success. In this post, we will cover the science of prenatal milk production, practical preparation steps, and how to build a strong foundation for your breastfeeding journey.
Preparing for breastfeeding is about more than just physical milk production; it involves education, support, and the right mindset. While you cannot "force" a full milk supply to appear during pregnancy, you can certainly pave the way for a robust supply once your baby is born.
To understand what you can do now, it is helpful to know how your body makes milk during pregnancy. This process is called Lactogenesis I. It usually begins around the midpoint of your pregnancy. During this stage, your breasts begin to produce colostrum.
Colostrum is often called "liquid gold." It is a thick, concentrated milk that is high in protein and antibodies. It is exactly what a newborn needs in those first few days. However, you will not produce large volumes of milk yet. High levels of progesterone during pregnancy keep your milk from "coming in" fully.
Once the placenta is delivered after birth, your progesterone levels drop. This drop signals your body to move into Lactogenesis II. This is when your milk volume increases significantly. Because this process is triggered by hormones, you cannot significantly increase your volume through diet or pumping while you are still pregnant.
Key Takeaway: Your milk supply during pregnancy is controlled by hormones, not by how much you eat or pump. Your body is already making colostrum, which is the perfect first food for your baby.
One of the most effective things you can do while pregnant to support your future milk supply is learning hand expression. This is a technique where you use your hands to gently compress the breast tissue to express colostrum. Many lactation experts recommend starting this around 36 or 37 weeks of pregnancy.
Hand expression helps you become familiar with your breast tissue. It teaches you how your milk flows. For some parents, collecting small amounts of colostrum before birth provides a "safety net" if the baby needs extra supplementation in the early days.
Always consult your healthcare provider before starting hand expression. In some cases, nipple stimulation can cause uterine contractions. Your doctor or midwife can tell you if it is safe for your specific pregnancy.
Knowledge is one of the best tools for maintaining a healthy milk supply. Many breastfeeding challenges arise from a lack of information rather than a physical inability to make milk. Understanding the "supply and demand" rule is vital.
Breastfeeding is a demand-driven process. The more milk is removed from the breast, the more milk your body will make. During your pregnancy, take the time to learn about:
Our team at Milky Mama offers Breastfeeding 101 and other online breastfeeding classes that cover these topics in detail. Taking a class while you are still pregnant can reduce anxiety and help you feel prepared for the first few weeks at home.
Some medical conditions can impact how quickly your milk comes in or how much you produce. Identifying these during pregnancy allows you to create a plan with a professional.
Knowing your medical history helps you and your care team stay proactive. If you have any of these conditions, you may want to schedule a prenatal consultation with a lactation professional through our Certified Lactation Consultant Breastfeeding Help page.
Your environment plays a massive role in your breastfeeding success. Stress can inhibit the hormone oxytocin. Oxytocin is responsible for the "let-down reflex," which is the process of milk moving through the ducts to the nipple.
While you are pregnant, set up a comfortable spot for feeding. This area should include:
One of our favorite ways to prep is by stocking up on nourishing treats. Our Emergency Lactation Brownies are a popular choice for many families. Having these ready in your pantry can take one thing off your plate during those early postpartum days.
The first hour after birth is often called the Golden Hour. This is a critical time for establishing your milk supply. Talk to your birth team about your desire for immediate skin-to-skin contact.
When your baby is placed on your bare chest, it triggers the release of hormones in both you and the baby. This helps the baby find the breast and encourages the first latch. Skin-to-skin contact is not just for the first hour; it is beneficial throughout the entire breastfeeding journey. It helps regulate the baby’s temperature and heart rate while signaling your body to produce more milk.
Action Steps for Your Birth Plan:
While you cannot "eat your way" to a higher supply during pregnancy, maintaining a healthy diet supports the development of your baby and your own energy levels. Your body requires extra calories to produce milk, so your prenatal nutrition is the foundation.
Ensure you are getting enough iron, calcium, and protein. Leafy greens, lean proteins, and healthy fats are all excellent choices. You should also continue taking your prenatal vitamin as directed by your doctor.
Breast milk is mostly water. If you are dehydrated, your body may struggle to maintain its energy. Get into the habit of carrying a water bottle now. This habit will serve you well once you are nursing and find yourself feeling more thirsty than usual.
Many parents look into herbal supplements while pregnant. It is important to know that most lactation supplements are intended for use after the baby is born. During pregnancy, your hormones are already doing the heavy lifting.
However, you can research which supplements might be right for you later. We offer a variety of herbal lactation supplements like Lady Leche™ and Pumping Queen™. These are designed to support milk flow and supply once your journey has begun.
For parents who want a broader overview, our Lactation Supplements collection is a helpful place to explore options after birth.

Breastfeeding is a skill that both you and your baby have to learn together. It is natural for it to feel difficult at first. One of the best things you can do while pregnant is to give yourself grace.
Every drop of colostrum you provide is valuable. If you find that you need to supplement or use a pump, that does not mean you have failed. Success is defined by a healthy baby and a healthy parent. Surround yourself with supportive people who will encourage you without judgment.
Most insurance providers in the United States cover the cost of a breast pump. The last month of pregnancy is an ideal time to order yours. You do not need to use it yet, but you should become familiar with how it works.
Read the manual and wash the parts according to the manufacturer’s instructions. Having your pump ready to go will reduce stress if you need to use it shortly after birth.
If pumping support is on your radar, you may also want to browse our Lactation Drink Mixes collection so you have a convenient hydration option ready for postpartum.
If you are currently breastfeeding an older child while pregnant with a new baby, you might notice your supply dropping. This is very common. The pregnancy hormones that support your growing baby often cause a decrease in milk volume around the fourth or fifth month.
In this situation, you cannot usually increase your supply through pumping or diet. Your body is shifting its resources to the pregnancy. Some children will continue to "dry nurse" for comfort, while others may choose to wean. If you plan to tandem nurse (feeding both the newborn and the older child), your supply will typically increase significantly once the new baby is born and the placenta is delivered.
Preparing to breastfeed is an exciting part of the pregnancy journey. While you cannot "pre-make" a large milk supply, your proactive steps today will make a difference tomorrow. By focusing on education, practicing hand expression, and ensuring you have a strong support system, you are giving yourself the best start possible.
Remember that every breastfeeding journey is unique. Your body was designed to nourish your baby, and you are doing an amazing job just by learning and preparing. We are here to support you every step of the way with resources and encouragement.
If you want more guidance as your due date gets closer, our virtual lactation consultations can help you feel more prepared and supported.

Most lactation supplements are designed to be used after your baby is born and your milk has transitioned. It is always best to wait until after birth to start herbal supplements, as your pregnancy hormones are already managing your milk production stages. Always consult your healthcare provider before starting any new supplement during pregnancy.
Pumping during pregnancy is generally not recommended unless specifically advised by a medical professional. It does not usually increase your future supply because pregnancy hormones prevent the "full" milk transition. Additionally, nipple stimulation can sometimes trigger uterine contractions, so it should be avoided unless cleared by your doctor.
No, breast size is not an indicator of how much milk you will produce. Milk production happens in the glandular tissue, not the fatty tissue that determines breast size. People of all breast shapes and sizes can successfully produce a full milk supply for their babies.
The most important thing you can do is have frequent skin-to-skin contact and nurse your baby as often as they show hunger cues. This early and frequent removal of colostrum tells your body to increase production. If the baby is unable to latch, hand expression or pumping can help signal your body to start making more milk.
