Introduction

Finding out you are expecting while still breastfeeding your older child brings up a mix of big emotions. You might feel excitement for the new addition and a deep desire to continue the nursing bond you have already established. Many mothers wonder if they can keep up their supply or if they need to change their routine. At Milky Mama, we are here to support you through every stage of your lactation journey, including the unique experience of nursing through pregnancy.

If you need more personalized guidance, our breastfeeding help and virtual consultation page is a helpful next step for one-on-one support.

This post will explore the hormonal changes that affect your milk, practical ways to support your body, and how to manage the physical challenges of "nursing for two." While your body undergoes major shifts to support the new life growing inside you, there are steps you can take to feel empowered. We will cover nutrition, hydration, and the reality of how pregnancy hormones interact with milk production.

Our goal is to give you the tools and confidence to navigate this transition. Whether you plan to tandem nurse—which means breastfeeding both your newborn and your older child—or simply want to maintain your current supply as long as possible, your well-being matters. Every drop counts, and you are doing an amazing job balancing the needs of your growing family.

The Science of Pregnancy and Lactation

To understand how to increase milk supply while pregnant, we first have to look at what is happening inside your body. Breastfeeding is typically a "supply and demand" process. When a baby removes milk, your body produces more. However, pregnancy introduces a new set of rules driven by powerful hormones.

For a deeper look at the basics of supply and demand, you can also read our guide on how to increase the supply of breast milk naturally.

During pregnancy, your levels of progesterone rise significantly. Progesterone is essential for maintaining a healthy pregnancy, but it also acts as a natural inhibitor of milk production. It specifically works against prolactin, the hormone responsible for making milk. This is why many mothers notice a dip in their supply as early as the first trimester, even if their older child is nursing frequently.

Around the second trimester, your milk also begins to transition. Your body starts preparing to feed a newborn, which means your mature milk slowly changes back into colostrum. Colostrum is often called "liquid gold" because it is packed with antibodies and nutrients. It has a different taste and a much thicker consistency than mature milk. Some toddlers love this change, while others might find the saltier taste or lower volume leads them to nurse less often.

Key Takeaway: Milk supply changes during pregnancy are primarily hormonal, not just based on how often you nurse. Understanding this shift can help reduce the stress of a naturally decreasing supply.

Can You Actually Increase Supply While Pregnant?

This is the question most moms want to answer. When you are not pregnant, the solution to a supply drop is often "power pumping" or nursing more often. When you are pregnant, those methods may not work the same way. Because the drop is driven by progesterone, your body may not respond to increased demand with a significant increase in volume.

If pumping is already part of your routine, our guide on power pumping for breastfeeding can help you think through stimulation strategies.

However, you can still take active steps to support the supply you do have. The goal shifts from "increasing volume at any cost" to "maximizing your body’s potential and maintaining health." For many women, supply stays steady enough to continue nursing until the new baby arrives. For others, the supply may drop to a very small amount, leading to "dry nursing."

It is important to manage expectations during this time. Your body is prioritizing the growth of your new baby. If your nursing child is under one year old, you must work closely with a pediatrician or an International Board Certified Lactation Consultant (IBCLC). They will help ensure your baby is getting enough calories from other sources if your supply decreases.

What to Do Next:

Track your nursing child's wet diapers and weight gain if they are under one year old.
Observe your child’s behavior at the breast to see if they are frustrated by a slower flow.
Focus on your own energy levels and physical comfort.

Nutritional Foundations for the Nursing Mother

Your nutritional needs increase significantly when you are both pregnant and breastfeeding. You are essentially fueling three people: yourself, your nursing child, and your developing baby. This requires a focus on nutrient-dense foods that provide lasting energy.

If you want a broader food-and-drink overview, our guide on what to eat or drink to increase milk supply offers more meal and hydration ideas.

Most experts suggest that breastfeeding while pregnant requires an extra 500 to 800 calories per day, depending on the age of your nursing child. If you are struggling with morning sickness, hitting these numbers can be hard. Focus on small, frequent meals rather than three large ones. High-protein snacks like Greek yogurt, nuts, and eggs can help keep your energy stable.

Iron and calcium are also vital during this time. Your body will prioritize the developing fetus, which can leave you feeling depleted if your intake is low. Leafy greens, lean meats, and fortified cereals are great options. We also recommend discussing a high-quality prenatal vitamin with your healthcare provider to fill any gaps in your diet.

Foods to Focus On:

Oats and Flaxseed: These are classic ingredients for supporting lactation. Our Emergency Lactation Brownies are a favorite for busy moms because they include these ingredients in a delicious, easy-to-grab treat.
Healthy Fats: Avocado, olive oil, and salmon provide DHA, which is crucial for baby’s brain development and your own hormonal health.
Protein: Aim for a serving of protein at every meal to support tissue growth for both babies.

Hydration and Its Role in Milk Production

Hydration is one of the most important factors in maintaining any milk supply, but it is especially critical during pregnancy. Your blood volume increases tremendously when you are pregnant, and your body needs extra water to manage this change while also producing milk.

If you are dehydrated, your milk supply is often the first thing to suffer. Aim for at least 8 to 12 cups of water a day. If plain water feels boring or triggers nausea, try adding fruit slices or drinking herbal teas that are safe for pregnancy.

To help make hydration more effective, we suggest incorporating electrolytes. Our Pumpin' Punch™ drink mix is a great way to stay hydrated while also including ingredients that support lactation. It provides a refreshing boost without the need for sugary sodas or excessive caffeine, which can actually lead to further dehydration.

If you like having a few options on hand, the lactation drink mixes collection is another easy place to start.

Key Takeaway: Increasing your fluid intake is the simplest and most effective way to support your milk supply and your pregnancy health simultaneously.

Managing Discomfort and Sensitivity

One of the biggest hurdles to nursing while pregnant is nipple sensitivity. Pregnancy hormones can make your breasts and nipples feel incredibly tender. For some moms, this makes breastfeeding feel uncomfortable or even painful.

If you are experiencing pain, the first step is to check the latch. Even an older child can sometimes develop a shallow latch that causes irritation. You can also try different nursing positions to change where the pressure is applied to the nipple. Using a high-quality nipple balm or even a few drops of expressed milk on the skin can help soothe soreness.

If latch concerns are making feeds harder than usual, our breastfeeding help page can connect you with additional support.

Another common experience is "nursing aversion." This is a feeling of intense irritability or restlessness when the child latches. It is a physiological response to hormones and is very common. If you feel this, try using distraction techniques, like listening to music or a podcast, or setting a timer for nursing sessions. It is okay to set boundaries and limit the length of feeds to protect your own mental health.

Tips for Physical Comfort:

Wear a supportive, non-wired nursing bra.
Use warm or cold compresses before and after nursing.
Practice deep breathing or "grounding" techniques if you feel nursing aversion.

Transitioning to Colostrum

As you move into the second half of your pregnancy, your body will naturally begin to produce colostrum. This is a normal part of the process and happens whether you are currently nursing or not. You cannot "run out" of colostrum. Your body will keep making it until your baby is born and your mature milk comes in a few days later.

For a related look at tandem nursing and the colostrum transition, you may also find supporting your journey during pregnancy useful.

Some mothers worry that the older child will "take" all the colostrum from the newborn. Rest assured, your breasts will continue to produce colostrum as long as the placenta is present. Once the newborn arrives, they will get exactly what they need. In fact, having an older child nursing can actually help your milk come in faster after birth because the "demand" is already established.

If your toddler notices the change in taste, they may naturally start to wean. This is often a very gentle way for the nursing relationship to change. If they continue to nurse, they will benefit from the incredible immune-boosting properties of the colostrum just as much as a newborn would.

Practical Tips for Tandem Nursing Success

If your goal is to tandem nurse once the new baby arrives, the work starts now. Tandem nursing can be a beautiful way to help an older sibling feel connected to the new baby. It can also help relieve engorgement when your milk comes in after delivery.

Preparation is key. Talk to your older child about the "new milk" coming for the baby. You might choose to create a special "nursing basket" filled with quiet toys or books that your older child only gets to play with while you are nursing the newborn. This helps them feel included and occupied.

If you want structured learning before baby arrives, our online courses collection is a good place to explore.

Remember that it is okay to prioritize the newborn's needs. Many moms find it helpful to nurse the newborn first to ensure they get the first serving of milk, then let the toddler nurse afterward. Your body is capable of producing enough milk for both, provided you are eating well and staying hydrated.

How to Prepare for Tandem Nursing:

Read books about siblings and breastfeeding with your older child.
Practice nursing in positions that could accommodate two children, like the "football hold."
Build a support system of friends or a group who have experience with tandem feeding.

Creating a Support System

Breastfeeding while pregnant is a feat of strength. It is physically and emotionally demanding. You may face questions or even criticism from people who do not understand why you are still nursing. Surround yourself with supportive people who validate your choices.

Whether it is an online community, a local lactation group, or your partner, having someone to talk to makes a difference. At Milky Mama, we believe that moms deserve support, not judgment. Your journey is unique to your family, and there is no "right" way to do it. If you need to scale back nursing for your own health, that is a valid choice. If you want to push through and tandem nurse, that is a valid choice too.

For moms who want ongoing education and more support options, the lactation supplements collection is another place to explore the brand’s support-focused products.

Don't be afraid to ask for help with household chores or childcare for your older child. Rest is a major component of milk production and pregnancy health. Even a 20-minute nap can help your body recover and keep up with the demands of "nursing for two."

When to Consult a Professional

While most women can safely nurse through pregnancy, there are times when medical advice is necessary. If you have a history of preterm labor or are experiencing unexplained uterine pain or bleeding, speak with your midwife or OB-GYN immediately. While breastfeeding releases oxytocin, the hormone that causes contractions, the uterus usually does not have enough receptor sites to trigger labor until very late in pregnancy. However, every body is different.

If you are worried about your milk supply and your baby is under a year old, an IBCLC can help you create a plan. They can perform "weighted feeds" to see exactly how much milk your baby is getting and help you supplement safely if needed.

Key Takeaway: Trust your intuition. If something feels off, or if the physical toll is becoming too much, seek professional guidance to ensure the health of everyone involved.

Conclusion

Nursing while pregnant is a journey of transition. While pregnancy hormones might make it difficult to "increase" supply in the traditional sense, you can absolutely support your body and maintain a healthy nursing relationship. By focusing on nutrient-dense foods, staying hydrated with options like Pumpin' Punch™, and listening to your body's signals, you can navigate this season with confidence.

If you want to keep exploring supportive products for this season, the lactation snacks collection, lactation drink mixes collection, and breastfeeding help page are all good places to start.

Remember that breastfeeding is about so much more than just the milk. It is about comfort, connection, and security for your older child as they prepare for a big life change. Whether you choose to nurse all the way through or find that weaning is the better path for your family, you are doing a great job.

Prioritize Nutrition: Eat small, frequent, nutrient-dense meals.
Hydrate Constantly: Keep water and electrolytes nearby at all times.
Set Boundaries: It is okay to limit nursing sessions if you are in pain or feeling overwhelmed.
Trust Your Body: Your body knows how to prioritize the needs of both your nursing child and your growing baby.

At Milky Mama, we are here to provide the products and the community you need to thrive. You’ve got this, Mama.

FAQ

Can I use lactation supplements while pregnant?

Many herbal lactation supplements contain ingredients that have not been fully studied for safety during pregnancy. It is essential to consult with your healthcare provider before starting any new supplement or herb while expecting. If you want to compare support options, you can start with the lactation supplements collection and discuss anything new with your care team.

Will my older child be taking milk away from the new baby?

No, your body will continue to produce colostrum throughout the end of your pregnancy. The presence of the placenta ensures that colostrum is constantly being made. Once the baby is born and the placenta is delivered, your body will transition to mature milk for both children.

Does breastfeeding cause miscarriage or early labor?

For a low-risk pregnancy, breastfeeding is generally considered safe and does not increase the risk of miscarriage or preterm labor. The amount of oxytocin released during nursing is typically not enough to cause the cervix to open prematurely. If you have a high-risk pregnancy, always follow the specific advice of your medical provider.
