Finding out you are pregnant while still nursing an older child is a beautiful, whirlwind experience. It is a time filled with excitement for the new addition and, often, a bit of worry about how your current breastfeeding relationship might change. You may find yourself wondering if your body can truly handle the demands of growing a new life while continuing to nourish another.
The short answer is yes—for most healthy pregnancies, it is entirely safe and possible to continue nursing. However, many parents notice a significant dip in their production as the weeks progress. At Milky Mama, we believe that education is the ultimate tool for empowerment, especially when you are navigating the unique challenges of nursing during pregnancy.
This guide will explore why supply changes during pregnancy, how you can support your body through these shifts, and what practical steps you can take to maintain your nursing relationship. We want to help you feel confident that you can meet the needs of your growing family while prioritizing your own wellness. With the right nutritional support and a deep understanding of your body’s changes, you can navigate this transition with grace.
When you are pregnant and breastfeeding, your body is performing an incredible feat of biological multitasking. To understand how to support your supply, it is helpful to understand why it often decreases in the first place. This shift is not a failure of your body; it is a result of your body prioritizing the new pregnancy.
Around the fourth or fifth month of pregnancy, most nursing parents notice a drop in milk volume. This occurs primarily because of a surge in progesterone, a hormone produced by the placenta. While progesterone is vital for maintaining a healthy pregnancy, it also has a suppressive effect on the volume of milk your breasts produce. It essentially acts as a "brake" on the let-down reflex and overall production.
Additionally, your milk begins to transition back to colostrum. Colostrum is the thick, yellowish "first milk" that is highly concentrated with antibodies and nutrients. It is often referred to as liquid gold because of its role in jumpstarting a newborn’s immune system. Because colostrum is produced in smaller, more concentrated amounts than mature milk, your toddler may notice the change in both quantity and taste.
Key Takeaway: Milk supply drops during pregnancy are primarily driven by hormones, not a lack of effort. Understanding that this is a biological shift can help reduce the stress that often impacts supply further.
In a typical breastfeeding scenario, the "supply and demand" rule is king. If you want more milk, you remove more milk through frequent nursing or pumping. This signals your body to increase production. However, during pregnancy, the rules of the game change slightly because the hormonal influence is so strong.
While you should certainly continue to nurse or pump to maintain the demand, you may find that traditional methods like power pumping (pumping in short bursts over an hour) are less effective than they were before you were pregnant. Because the progesterone from your placenta is actively telling your body to slow down volume, you are working against a biological signal. For additional guidance, review this guide to power pumping for breastfeeding.
This does not mean you should stop trying. Frequent removal of milk still helps maintain the "infrastructure" of your supply. However, it is important to manage your expectations. Instead of focusing solely on the number of ounces in a bottle, focus on the quality of your nutrition and the comfort of the nursing session.
When you are breastfeeding while pregnant, your caloric needs are significantly higher than average. You are not just "eating for two"—in a way, you are eating for three. Your body requires energy to support the developing fetus, the production of milk, and your own daily metabolic functions.
On average, a breastfeeding parent who is also pregnant may need an additional 500 to 800 calories per day. If you are experiencing morning sickness or a lack of appetite, meeting this goal can be difficult. However, staying well-nourished is one of the few ways you can directly influence your milk supply during this time.
Focus on nutrient-dense foods that support lactation. These are often called galactagogues—substances that may help support milk production. Common examples include:
We often recommend our Emergency Brownies for moms looking for a delicious way to incorporate these ingredients. They are specifically formulated to support supply and provide a much-needed energy boost for busy, expectant parents.
Staying hydrated is essential for milk production, but when you are pregnant, your fluid requirements increase even further. Your body is expanding its blood volume to support the placenta and the baby, which means you need more water than ever before.
Many parents find that plain water isn't enough to keep them feeling truly hydrated, especially if they are dealing with pregnancy-related fatigue or nausea. This is where electrolytes come into play. Electrolytes like magnesium, potassium, and sodium help your body actually absorb the water you drink.
To support your hydration levels, aim for at least 80 to 100 ounces of fluid daily. If you struggle with the taste of plain water, our lactation drink mixes like Pumpin Punch™ or Milky Melon™ can be a great alternative. These drinks provide hydration along with lactation-supportive ingredients, making it easier to reach your daily goals without feeling like drinking water is a chore.
One of the most common reasons parents choose to wean during pregnancy is nipple sensitivity. The same hormones that support your pregnancy—estrogen and progesterone—can make your breasts and nipples feel incredibly tender. For some, the sensation of nursing can even become painful or irritating, a feeling sometimes called "nursing aversion."
If you want to continue breastfeeding but are struggling with discomfort, there are several things you can try:
When nutrition and hydration aren't enough to keep your supply where you want it, some parents turn to herbal supplements. It is vital to choose supplements that are generally considered safe for use during pregnancy, as some herbs traditionally used for milk supply should be avoided while expecting.
Herbs like Alfalfa, Blessed Thistle, and Goat’s Rue are often used by lactation professionals to support supply. At Milky Mama, we offer several herbal blends designed by our founder, Krystal Duhaney, who is a Registered Nurse and IBCLC. Products like Lady Leche™ or Pump Hero™ are popular choices for those looking to provide their body with extra support.

As you move into the second trimester, you may find that your supply drops to almost nothing. This is often referred to as "dry nursing." Some children will continue to nurse for comfort even if they are receiving very little milk. Others may become frustrated and choose to wean on their own.
If your child is under one year old and your supply drops significantly, it is important to work with your pediatrician to ensure they are receiving adequate nutrition from a supplemental source, such as formula or expressed milk from a donor. If your child is over a year old, they can usually compensate for the drop in milk by eating more solid foods and drinking water.
Around the midpoint of your pregnancy, your body will officially begin producing colostrum again. You might notice your "milk" looks thicker and more yellow. This colostrum is perfectly safe for your toddler to drink. In fact, it provides them with a massive boost of antibodies. One thing to be aware of: colostrum has a natural laxative effect. Don't be surprised if your toddler has slightly looser stools during this time—it’s just the "liquid gold" doing its work!
If you successfully maintain your supply (or your child continues to dry nurse) throughout your pregnancy, you may find yourself "tandem nursing." This simply means nursing both your newborn and your older child after the birth.
Many parents worry that the toddler will "steal" the colostrum from the newborn. Rest assured, your body is designed to produce enough for both. The act of the newborn nursing will signal your body to transition from colostrum back to mature milk, and the presence of two nursing children often results in a very robust milk supply.
Tandem nursing can be a wonderful way to help an older sibling transition to life with a new baby. It provides them with a consistent source of comfort and helps reduce feelings of jealousy. However, it can also be physically demanding. Make sure you are prioritizing your rest and continuing to use high-quality lactation snacks or supplements to keep your energy and supply high.
While a drop in supply is normal during pregnancy, there are times when you should seek the guidance of a professional. If you are feeling overwhelmed, experiencing significant pain, or are worried about your child’s nutrition, reach out for help.
A Certified Lactation Consultant (IBCLC) can help you:
At Milky Mama, we offer virtual lactation consultations to provide you with expert support from the comfort of your home. You don't have to navigate these changes alone; having a professional in your corner can make all the difference in reaching your breastfeeding goals.
Breastfeeding while pregnant is a major physical and emotional commitment. It is important to remember that "success" isn't just measured in ounces or months. It is measured by the health and happiness of you and your children.
If you find that the drop in supply or the physical discomfort is too much, it is okay to consider weaning. If you decide to push through and tandem nurse, that is also a valid and wonderful choice. There is no one-size-fits-all answer. Your worth as a parent is not tied to your milk supply.
Every drop counts, and every moment of connection you share with your child matters. Whether you nurse through your entire pregnancy or decide to transition to a different feeding method, you are doing an amazing job.
Increasing or maintaining milk supply while pregnant requires a multi-faceted approach. While biology plays a large role, your actions can support your body’s ability to keep up with the demand.
"Breastfeeding is a journey that changes as your family grows. Whether you are nursing one or two, your body is doing incredible work, and you deserve all the support in the world."
If you are looking for ways to support your journey, consider exploring our range of lactation supplements.

Many lactation supplements are safe, but it is crucial to avoid certain herbs that can stimulate uterine contractions. Always choose a supplement specifically vetted for pregnancy and consult with your healthcare provider or a lactation consultant before starting any new herbal regimen.
A sudden drop in the second trimester is usually due to the significant increase in progesterone levels produced by the placenta. This hormone naturally suppresses milk volume as your body prepares to transition back to producing colostrum for the new baby.
No, your body does not have a "limited" amount of colostrum. Your breasts will continue to produce colostrum throughout the end of your pregnancy and the first few days after birth, ensuring both your toddler and your newborn receive the nutrients they need.
While pumping can help maintain the demand, it is often less effective at increasing volume during pregnancy than it is postpartum. This is because the hormonal "brakes" put on by the pregnancy are often stronger than the "supply and demand" signals sent by the pump.
