Picture this: You’ve finally found your rhythm with breastfeeding. Your little one is thriving, the middle-of-the-night feeds have become a time of quiet bonding, and you feel like you’ve truly mastered the "liquid gold" game. Then, you see it—the two pink lines on a pregnancy test. Suddenly, your mind is racing with a million questions. Can I still nurse my toddler? Will my milk dry up? Most importantly, what can you do to increase milk supply while pregnant?
If you are feeling a mix of excitement and anxiety, take a deep breath. You are not alone, and your body is doing something truly miraculous. It is simultaneously growing a new life and nourishing another. While breastfeeding during pregnancy—and potentially tandem nursing down the road—is a beautiful journey, it comes with its own unique set of physiological changes. Many moms notice a dip in their supply as early as the first trimester, leading to concerns about whether their older child is getting enough.
In this post, we are going to dive deep into the science of what happens to your milk supply during pregnancy. We will explore why supply often decreases, practical steps you can take to support your production, and how to manage the physical and emotional shifts that come with this "overlap" period. Our goal is to empower you with evidence-based information and compassionate support, because at Milky Mama, we believe every drop counts—and your well-being matters too.
The first question most families ask is whether continuing to nurse is safe for the developing baby. For the vast majority of healthy, low-risk pregnancies, the answer is a resounding yes.
A common myth is that the oxytocin released during breastfeeding could trigger preterm labor. However, your body is incredibly smart. Research shows that while oxytocin is responsible for the "let-down" reflex, the uterus is generally not sensitive to these small amounts of the hormone until very late in pregnancy. There are "triple protection" safeguards in place: the number of oxytocin receptors in the uterus remains low until about 38 weeks, and hormones like progesterone (produced by the placenta) act as blockers to prevent the uterus from reacting too early.
If you are able to safely have sexual intercourse, you are almost certainly safe to continue breastfeeding. However, we always recommend staying in close contact with your healthcare provider. If you have a high-risk pregnancy, a history of preterm labor, or are expecting multiples, your doctor or midwife may provide specific guidance tailored to your situation.
To understand what you can do to increase milk supply while pregnant, we first have to look at the "why" behind the dip. Usually, breastfeeding is a game of supply and demand—the more milk is removed, the more your body makes. But pregnancy changes the rules.
Around the end of the first trimester or the beginning of the second, many mothers notice a significant decrease in their milk volume. This isn't because you're doing anything wrong; it’s biology. The high levels of estrogen and progesterone required to maintain a healthy pregnancy naturally suppress milk production.
Between weeks 16 and 20 of pregnancy, your breasts begin a process called lactogenesis I. This is when your body starts producing colostrum—the thick, nutrient-dense "first milk" intended for your newborn. As this transition happens, your "mature" milk supply will naturally decrease and change in composition. Some toddlers may notice the change in taste (colostrum is often saltier and less sweet) and might choose to wean on their own, while others will happily keep nursing through the change.
For some moms, the supply may drop so low that they are essentially "dry nursing." This is when the child continues to suckle for comfort even though very little milk is being produced. Because breastfeeding is about so much more than just nutrition—it's about safety, connection, and relaxation—many children are perfectly content to continue nursing despite the lower volume.
While pregnancy hormones are the "boss" during this time, there are several things you can do to support your body and maintain as much supply as possible.
Your body is working overtime. You are nourishing yourself, growing a baby, and producing milk. This requires a significant amount of energy. On average, a breastfeeding person may need an additional 500 to 800 calories per day to support both pregnancy and lactation.
Focus on foods that are rich in:
To make meeting these caloric needs easier, we recommend keeping healthy snacks within arm's reach. Our Oatmeal Chocolate Chip Cookies or Salted Caramel Cookies are delicious ways to get in those extra calories while supporting your breastfeeding journey.
Dehydration is a common culprit for a dipping milk supply, and pregnancy increases your fluid requirements. You should be drinking enough that your urine is clear or very pale yellow. If plain water feels boring—especially if you’re dealing with pregnancy-related nausea—try something that offers a bit more.
Our Lactation LeMOOnade™ and Pumpin Punch™ are specifically designed to provide hydration along with lactation-supporting ingredients. They are refreshing, easy on the stomach, and a great way to ensure you're staying hydrated throughout the day.
While the supply-and-demand rule is dampened by pregnancy hormones, it isn't completely gone. Continuing to nurse your older child frequently can help signal to your body to keep producing. If your child is nursing less because of the change in taste or flow, you might consider a few short pumping sessions, though you should keep your expectations realistic. During pregnancy, pumping usually won't result in a massive "boost" in supply, but it can help maintain what you have.
Many moms turn to herbal supplements to help bridge the gap. However, it is vital to choose supplements that are safe for pregnancy. Many common lactation herbs are not recommended for use while pregnant.
At Milky Mama, we offer several herbal supplements that focus on supporting supply without the use of ingredients that are contraindicated during pregnancy. Our Pump Hero™ and Milky Maiden™ are popular choices for moms looking for extra support.

Even if you are doing everything right to support your supply, the physical experience of breastfeeding while pregnant can be tough.
One of the earliest signs of pregnancy is often nipple tenderness. This can make the "latch" of an older child feel quite uncomfortable, even if their latch was previously perfect.
Some pregnant moms experience a phenomenon called "nursing aversion." This is a sudden, intense feeling of irritability, restlessness, or a "skin-crawling" sensation when the older child latches. It is a hormonal response and is much more common than people realize.
When you are pregnant and breastfeeding, your nutritional "bank account" is being withdrawn from at a high rate. It is important to stay on top of your prenatal vitamins and consider additional support.
Pregnancy increases your blood volume, which can lead to anemia. Breastfeeding also requires iron. If your iron levels are low, you may feel even more exhausted than the typical "first trimester tired." Focus on iron-rich foods like beans, lentils, and fortified cereals, and talk to your doctor about having your levels checked.
If you’re looking for a boost that feels like a treat, our Emergency Brownies are a fan favorite for a reason. They are packed with ingredients that have been used for generations to support lactation. If you prefer a variety of flavors, our Fruit Sampler offers a great way to find your new favorite snack.
For those who prefer a liquid supplement, Lady Leche™ and Dairy Duchess™ provide concentrated herbal support that can be easily added to your daily routine. Again, always check with your midwife or OB-GYN to ensure these align with your specific pregnancy health plan.
Your older child might be the first one to notice that your supply is changing. Here is what to expect from them:
If you decide to continue breastfeeding through your pregnancy, you may be headed toward "tandem nursing"—feeding both the newborn and the older child. This can be a wonderful way to help an older sibling adjust to the new baby.
This is the number one concern for tandem-nursing moms. Rest assured, your body will prioritize the needs of the newborn. Once the placenta is delivered after birth, your progesterone levels will drop, and your "real" milk will come in, triggered by the needs of your new baby.
In the early days, it is often recommended to let the newborn nurse first to ensure they get the colostrum they need. However, having an older child nurse can actually be helpful! They are often more efficient at removing milk, which can help relieve engorgement and signal your body to increase production quickly.
Tandem nursing requires a lot of "you." It is perfectly okay to set boundaries. You might decide that the toddler only nurses at naptime and bedtime, while the newborn nurses on demand. Clear communication (even with a young toddler) and a supportive partner are key.
Breastfeeding is natural, but it doesn't always come naturally—especially when you add a pregnancy into the mix! If you are struggling with supply, pain, or just feel overwhelmed, please reach out for help.
We offer virtual lactation consultations where you can speak with an expert from the comfort of your home. Sometimes, just having an IBCLC look at your toddler's latch or help you create a nutrition plan can make all the difference. We also recommend our Online breastfeeding classes, such as Breastfeeding 101, to refresh your knowledge before the new baby arrives.
Let’s look at a common scenario: You’re 24 weeks pregnant, chasing a two-year-old, and your supply has noticeably dropped. Your toddler is asking to "num num" every hour because they aren't getting as much as they used to, and your nipples are sore.
In this situation, the best approach is multifaceted:
It is important to acknowledge the emotional weight of this time. You might feel guilty—guilty that your milk is changing for your toddler, or guilty that you're "sharing" resources with the new baby.
Please hear us: You are doing an amazing job.
The fact that you are even researching how to support your supply shows how much you care. Breastfeeding during pregnancy is an act of incredible generosity and love. It is okay to have days where you love it and days where you want to be done. Every journey is unique, and there is no "right" way to do this.
Yes, but you must be careful about the ingredients. Many herbs used in standard lactation supplements are not recommended during pregnancy. We suggest focusing on nutrition-based support like our lactation snacks and consulting with your healthcare provider before using herbal capsules like Pumping Queen™ or Milk Goddess™ to ensure they are appropriate for your specific stage of pregnancy.
Your body is designed to prioritize the baby, but it also has mechanisms to protect you. During pregnancy, your body actually becomes more efficient at absorbing calcium from your food. As long as you are eating a balanced, calorie-sufficient diet and taking your prenatal vitamins, you can maintain your health while nursing. Studies show that tandem-nursing mothers do not have an increased risk of osteoporosis later in life.
This is common as your milk transitions to colostrum, which is higher in sodium. If your toddler is frustrated by the taste, you can try offering a small snack or a cup of milk (if they are over a year old) alongside nursing. Some children will decide to wean because of the taste change, while others will get used to it. Follow your child's lead.
During pregnancy, the drop in supply is primarily hormonal, not just a matter of "emptying the breast." While pumping provides stimulation, it may not result in the same supply increase you would see when not pregnant. However, many moms find that light pumping helps them feel like they are "doing something" to maintain the habit and keep the milk ducts active.
Navigating the world of breastfeeding while pregnant can feel like walking a tightrope, but we are here to hold the safety net for you. Whether your goal is to tandem nurse or simply to provide as much milk as possible for your older child during this transition, remember that you are doing something beautiful. Your body was literally created to feed human babies, and its ability to adapt is nothing short of a miracle.
