Introduction
As you navigate the final weeks or months of pregnancy, it is completely natural to start thinking about life after birth. Many expectant parents find themselves "nesting" not just by folding tiny clothes, but by wondering how they will nourish their new arrival. If you are asking what to eat during pregnancy to increase milk supply, you are already ahead of the curve. At Milky Mama, we know that preparing for your breastfeeding journey is one of the most empowering steps you can take for your peace of mind, and our breastfeeding help resources are there if you want extra support.
While the primary "trigger" for your milk to come in is the delivery of the placenta, the foundation for a healthy supply is built while you are still pregnant. This article will cover the essential nutrients your body needs to develop breast tissue, the best foods to stock in your pantry now, and how to set yourself up for a successful breastfeeding experience. Our goal is to help you feel confident that your body is already doing the incredible work of preparing to feed your baby.
How Your Body Prepares for Milk Production
Before we dive into specific foods, it is helpful to understand what is happening inside your body right now. Breastfeeding is a biological process that begins long before you hold your baby. During pregnancy, your body undergoes "lactogenesis I." This is the first stage of milk production where your breasts develop the necessary tissue and begin producing colostrum—the nutrient-rich "liquid gold" that is your baby's first food.
The actual increase in milk volume, often called "the milk coming in," is known as lactogenesis II. This usually happens between two and five days after birth. While you cannot technically "force" a large milk supply to appear while you are still pregnant, you can absolutely provide your body with the high-quality fuel it needs to build a robust system. Think of your pregnancy diet as the construction phase; you are making sure the "milk factory" is built with the best materials possible.
Key Takeaway: Your body is already preparing for lactation. Focus on nutrient-dense foods now to support breast tissue development and energy stores for the postpartum period.
Essential Nutrients to Prioritize During Pregnancy
To support the hormonal changes and physical demands of milk production, certain nutrients are vital. Your body prioritizes your baby's needs, often pulling nutrients from your own stores. Eating well now ensures there is plenty left over for your own wellness and energy.
Lean Proteins for Tissue Growth
Proteins are the building blocks of every cell in the body. During pregnancy, you are not only growing a baby but also expanding your own blood volume and developing glandular breast tissue. We recommend including a variety of protein sources in your daily meals.
- Chicken and Turkey: These are excellent sources of lean protein and are easy for many to digest.
- Eggs: Rich in choline, eggs support both your brain health and your baby’s development.
- Plant-Based Proteins: Beans, lentils, and tofu are fantastic options that also provide much-needed fiber.
Healthy Fats and DHA
Breast milk is naturally high in fat, which is essential for your baby’s brain and nervous system. Consuming healthy fats during pregnancy may help ensure your body has the reserves needed to produce high-quality milk later. Omega-3 fatty acids, specifically DHA (docosahexaenoic acid), are particularly important.
- Low-Mercury Fish: Salmon and sardines are wonderful sources of DHA.
- Avocados: These provide monounsaturated fats that keep you feeling full and energized.
- Walnuts and Chia Seeds: These are easy to toss into salads or yogurt for a quick boost of healthy fats.
Complex Carbohydrates for Sustained Energy
Making milk is hard work—it can actually burn 300 to 500 calories a day! You need sustained energy to keep up with these demands. Complex carbohydrates break down slowly, providing a steady stream of glucose to your system rather than a quick spike and crash.
- Quinoa and Brown Rice: These grains are packed with minerals and B vitamins.
- Sweet Potatoes: A great source of Vitamin A and energy-giving carbs.
- Oats: Often cited as a top food for lactation, oats are rich in iron and fiber.
Top Foods to Support Future Milk Supply
While many people wait until after the baby is born to start eating "lactation foods," incorporating them into your pregnancy diet can be very beneficial. These foods are often called galactagogues (pronounced gah-lak-tah-gogs), which are substances that may help support or increase milk production in many people.
Oats and Whole Grains
Oats are perhaps the most famous food for milk supply. They are a great source of iron, and low iron levels are sometimes linked to a lower milk supply. Eating oatmeal for breakfast during pregnancy is a gentle way to support your body. Our Emergency Lactation Brownies are a fan-favorite way to enjoy oats and other supply-supporting ingredients in a delicious, ready-to-eat treat.
Leafy Green Vegetables
Dark leafy greens like spinach, kale, and alfalfa are nutritional powerhouses. They contain phytoestrogens, which are plant-based compounds that may have a positive effect on milk production. They are also high in calcium and iron, which are essential for both pregnancy and breastfeeding.
Raw Nuts and Seeds
Almonds, in particular, are often recommended by lactation consultants. They are non-dairy sources of calcium and are rich in healthy fats. Flaxseeds and sesame seeds also contain lignans, which can help support hormonal balance.
Hydrating Fruits and Vegetables
Staying hydrated is one of the most important factors in maintaining a healthy milk supply. While you don't need to over-hydrate, drinking to satisfy your thirst is key. Foods with high water content can help.
- Melons: Watermelon and cantaloupe are hydrating and refreshing.
- Cucumbers: These are mostly water and make a great snack.
- Berries: Packed with antioxidants and fiber to help with pregnancy-related digestion issues.
What to Do Next:
- Add one serving of oats to your daily routine (oatmeal, granola, or oat-based snacks).
- Incorporate a handful of raw almonds into your afternoon snack.
- Ensure you have a leafy green vegetable with at least one meal per day.
- Stock your pantry with nourishing snacks so you are ready for the first few weeks at home.
The Role of Hydration
It is a common myth that you must drink gallons of water to make milk. In reality, forced over-hydration can sometimes have the opposite effect. However, dehydration is a definite supply-killer. During pregnancy, your blood volume increases significantly, requiring more fluids. Establishing a good hydration habit now will serve you well once you begin breastfeeding.
We suggest keeping a reusable water bottle with you at all times. If plain water feels boring, you can try infusing it with fruit or sipping on something like Pumpin' Punch, which provides hydration alongside lactation-supportive ingredients. Aim for your urine to be pale yellow—that is the best sign that you are well-hydrated.
Preparing Your Pantry for the Fourth Trimester
The "fourth trimester" refers to the first three months after your baby is born. This is a time of intense recovery and learning. One of the best things you can do during pregnancy to support your future milk supply is to prep your kitchen. When you are tired and holding a newborn, you are unlikely to want to cook complex meals.
- Freeze-Ahead Meals: Prepare soups, stews, and casseroles that include supply-supporting ingredients like beans, spinach, and brown rice.
- Lactation Snacks: Have items like our lactation snacks collection on hand. They are designed to be an easy, grab-and-go way to get the nutrients you need while you are busy with your little one.
- Herbal Support: Many parents find that herbal supplements can provide an extra boost. Products like Pumping Queen or Lady Leche are popular choices for those looking to support their supply naturally.

Habits That Support Supply Beyond Nutrition
While what you eat is important, breastfeeding is also a "supply and demand" system. The more milk that is removed from the breast, the more milk your body will make. During pregnancy, you can prepare for this by learning the mechanics of a good latch and understanding infant feeding cues through our Breastfeeding 101 course and related education.
Skin-to-Skin Contact
Research shows that spending time skin-to-skin with your baby immediately after birth (and in the weeks following) helps regulate the baby’s temperature and heart rate while also triggering the release of oxytocin. Oxytocin is the hormone responsible for the "let-down reflex," which is the process of milk being squeezed out of the milk ducts.
Rest and Stress Management
It sounds impossible with a newborn, but rest is vital for milk production. High levels of stress hormones like cortisol can sometimes interfere with the let-down reflex. During pregnancy, practice relaxation techniques that you can carry into the postpartum period. Accept help from friends and family so you can focus on feeding and resting.
Key Takeaway: Nutrition is the fuel, but "supply and demand" is the engine. Combine a healthy diet with frequent feedings and plenty of skin-to-skin time.
What to Avoid for a Healthy Supply
While focusing on what to add to your diet, it is also helpful to know what might hinder your progress.
- Strict Calorie Restriction: Pregnancy and breastfeeding are not the times for restrictive dieting. Your body needs extra energy to produce milk. Focus on the quality of your calories rather than cutting them.
- Excessive Caffeine: While a cup of coffee is generally fine, too much caffeine can sometimes make babies irritable or interfere with your own ability to rest when you have the chance.
- Sage, Parsley, and Peppermint: In very large culinary amounts, these herbs are sometimes used by those trying to decrease their milk supply during weaning. You don't need to worry about a garnish, but avoid consuming them in medicinal quantities.
- Decongestants: Some over-the-counter cold medications can temporarily dry up secretions, including breast milk. Always check with your doctor before taking medications while breastfeeding.
Every Drop Counts
Breastfeeding is a journey that looks different for everyone. Some parents find that their milk comes in quickly and abundantly, while others may need a bit more time and support to establish their supply. Please remember that you are doing an amazing job. Whether you provide one ounce or thirty ounces a day, the effort you put into nourishing your baby is incredible.
At Milky Mama, we believe in supporting you through every stage—from those curious questions during pregnancy to the late-night pumping sessions. Breasts were literally created to feed human babies, and your body is a powerful system. By focusing on nutrient-dense foods and staying hydrated now, you are laying a beautiful foundation for your baby's growth and your own wellness.
Summary of Next Steps
Preparing for your breastfeeding journey while pregnant is a proactive way to reduce stress later. Here is a quick checklist of what to focus on:
- Eat for Energy: Focus on lean proteins, complex carbs, and healthy fats.
- Incorporate Galactagogues: Start enjoying oats, almonds, and leafy greens now.
- Hydrate Early: Build the habit of drinking 80-100 ounces of fluid daily.
- Educate Yourself: Learn about supply and demand and infant feeding cues with Pumping & Breastfeeding: Understanding When and Why.
- Prep Your Stash: Get your lactation drink mixes and lactation treats ready for the postpartum period.

FAQ
Can I start drinking lactation tea while I am still pregnant?
Most lactation teas are safe during the third trimester, but it is always best to check with your healthcare provider first. Some herbs may not be recommended during pregnancy even if they are helpful during lactation. We generally recommend focusing on whole foods like oats and almonds during pregnancy and saving the more potent herbal blends for after the baby arrives.
How many extra calories do I need to make milk?
On average, your body needs about 300 to 500 extra calories per day to maintain a healthy milk supply. This is in addition to the calories you already need for your daily activities and recovery from birth. Focus on getting these calories from nutrient-dense sources like avocados, nuts, and whole grains to keep your energy levels stable.
Does drinking more water guarantee more milk?
Hydration is necessary for milk production, but drinking an excessive amount of water will not "guarantee" a higher supply. Breast milk is roughly 87% water, so staying hydrated ensures your body has the raw materials it needs. However, the most important factor in supply remains the frequent removal of milk through nursing or pumping. If you want a simple way to build a hydration habit, our lactation drink mixes can help you stay consistent.
Are there any foods I should avoid because they cause gas in the baby?
Most babies are not affected by the "gassy" foods their parents eat, such as broccoli or beans. The flavors of your food do pass into your milk, which is actually a great way to prepare your baby for solid foods later. If you notice your baby is consistently fussy after you eat a specific food, you can try eliminating it for a few days to see if there is a difference, but there is no need to avoid these healthy foods preemptively. If you want more personalized guidance, our Certified Lactation Consultant Breastfeeding Help page is a good place to start.
