Introduction
Finding out you are expecting a new baby while still breastfeeding an older child is a moment filled with many different emotions. You might feel excitement for the new addition and a bit of worry about how your current nursing relationship will change. It is very common for parents to wonder if they can maintain their milk supply as their pregnancy progresses. At Milky Mama, we understand that you want to provide the best for both your growing baby and your nursing toddler.
This article will explore the biological changes that happen when you are pregnant and breastfeeding at the same time, and our Breastfeeding Through Pregnancy guide is a helpful companion read. We will cover how pregnancy hormones affect milk production and what steps you can take to support your body. We will also discuss nutrition, hydration, and how to prepare for the arrival of your newborn. Our goal is to provide you with the clinical knowledge and compassionate support you need to navigate this unique journey.
Every drop counts, and your dedication to your children is truly remarkable. While the body undergoes significant shifts during these nine months, there are ways to manage your supply and keep yourself healthy. This guide provides practical strategies to help you navigate the changes in your milk supply while expecting your next little one.
The Reality of Milk Supply During Pregnancy
When you become pregnant, your body begins a complex hormonal dance to support the new life growing inside you. These changes are beautiful, but they can have a direct impact on your current milk production. For most people, milk supply will naturally decrease during pregnancy, regardless of how often you nurse or pump.
This drop usually happens during the second trimester, around the fourth or fifth month. It occurs because levels of estrogen and progesterone rise significantly. These hormones are essential for maintaining a healthy pregnancy, but they also act as a "brake" on the hormone prolactin. Prolactin is the hormone responsible for telling your body to make milk.
Understanding the Hormonal Shift
During the first few months, you might not notice much of a change. However, as the placenta grows and produces more hormones, the signal to produce mature milk weakens. This is a normal biological process. Your body is slowly shifting its resources toward the final stages of pregnancy.
Around the middle of your pregnancy, your milk will transition from mature milk back into colostrum. Colostrum is the thick, yellow, nutrient-dense "first milk" that is high in antibodies. It is perfectly designed for a newborn baby. While this is amazing for your upcoming arrival, your older nursing child might notice a change in the taste or the amount available, and our colostrum supply guide explains that transition in more detail.
Key Takeaway: A decrease in milk supply during pregnancy is primarily driven by hormones, not a lack of effort or demand.
Signs of a Decreasing Supply
It is helpful to know what to look for so you aren't caught off guard. You might notice:
- Your nursing child spending more time at the breast to get the same amount of milk.
- Increased tugging or frustration from your toddler during sessions.
- A visible change in the color and consistency of your milk.
- Your breasts feeling softer or "emptier" than usual.
Can You "Boost" Supply While Pregnant?
In a typical breastfeeding scenario, we talk about "supply and demand." This means the more milk you remove, the more milk your body makes. However, pregnancy changes the rules of this game. Because the drop in supply is caused by pregnancy hormones in your blood, simply nursing more often or power pumping may not have the same effect it usually does.
This can be frustrating for many parents. You might feel like you are doing everything right, yet the numbers on the pump or the length of the nursing session tell a different story. It is important to be kind to yourself during this time. You are already doing the incredible work of growing a human being while nourishing another.
Managing Expectations
While you may not be able to force your supply back to pre-pregnancy levels, you can focus on "maintenance and support." This means ensuring your body has every tool it needs to produce whatever milk it can. For many, this results in a "dry nursing" period where the toddler continues to nurse for comfort even if very little milk is produced.
If your nursing child is under 12 months old, it is vital to work closely with a pediatrician. Since their primary nutrition must come from milk or formula, a drop in your supply might mean they need additional supplementation to stay on track with their growth.
What to do next:
- Monitor your older child’s weight and wet diapers.
- Discuss supplementation with your healthcare provider if your child is under one year old.
- Adjust your nursing schedule to focus on comfort and connection rather than just volume.
- Pay close attention to your own energy levels.
Nutrition for the Expectant and Nursing Mom
Your nutritional needs are at an all-time high when you are "double-producing." Your body is prioritizing the fetus first, your own health second, and your milk supply third. To support your milk production, you must ensure you are eating enough calories and the right nutrients.
Most experts suggest that a pregnant person who is also breastfeeding needs an additional 500 to 800 calories per day. This number can vary based on your activity level and the age of your nursing child. If you are struggling with morning sickness, hitting these goals can be difficult.
Focus on Nutrient-Dense Foods
When every bite counts, focus on foods that provide "more bang for your buck."
- Protein: This is the building block for your baby’s growth and your milk production. Aim for lean meats, beans, eggs, and Greek yogurt.
- Complex Carbohydrates: Oats are a classic galactagogue. They provide steady energy and fiber.
- Healthy Fats: Avocados, nuts, and seeds support brain development for the baby and keep you feeling full.
Our Emergency Brownies are one of our most-loved lactation treats, and they are a convenient way to get a calorie boost. They are packed with ingredients like oats and flaxseed that support lactation while giving you a much-needed snack during a busy day.
Essential Vitamins and Minerals
Don't forget your prenatal vitamin! It is more important than ever. Specifically, keep an eye on your iron and calcium levels. Anemia (low iron) is common in pregnancy and can contribute to low milk supply and extreme fatigue. If you feel excessively tired, ask your provider for a blood test to check your iron levels.
Key Takeaway: Your body will prioritize the growing pregnancy, so you must eat enough to support both the baby and your milk supply.
The Importance of Hydration
Hydration is a cornerstone of milk production. When you are pregnant, your blood volume increases significantly, which requires a lot of water. If you are dehydrated, your body will preserve fluids for vital functions, often leaving milk production at the bottom of the list.
It isn't just about plain water, though. Electrolytes help your body actually absorb the fluids you drink. If you find yourself running to the bathroom constantly but still feeling thirsty, you might need more electrolytes.
Smart Hydration Strategies
Drinking a gallon of water a day can feel like a chore, especially if you have a toddler running around. Try these tips:
- Carry a reusable water bottle everywhere.
- Use a straw, which often helps people drink more without thinking about it.
- Eat hydrating foods like watermelon, cucumbers, and oranges.
To make hydration more enjoyable, we offer options like our Pumpin Punch™ drink mix or our Lactation Drink Mixes collection. These are designed to provide hydration along with ingredients that support lactation, making it easier to hit your daily fluid goals without feeling bored by plain water.
What to do next:
- Aim for pale, straw-colored urine as a sign of good hydration.
- Drink a glass of water every time you sit down to nurse or pump.
- Limit caffeine, as it can be dehydrating and may affect your sleep.
- Keep a bottle of water on your nightstand for middle-of-the-night thirst.
Managing Nipple Sensitivity and Discomfort
One of the biggest hurdles to maintaining supply while pregnant is physical discomfort. Many pregnant people experience extreme nipple sensitivity due to the increase in estrogen and progesterone. This can make the "let-down reflex" (the tingling feeling when milk starts to flow) feel uncomfortable or even painful.
In some cases, parents experience "nursing aversion." This is a sudden, strong feeling of agitation or the urge to pull the child away when they latch. If this happens to you, know that you are not alone and it is a biological response, not a reflection of your love for your child.
Tips for Comfortable Nursing
- Check the Latch: Even a toddler who has nursed for years might need a "latch tune-up" if your breast tissue is changing.
- Shorten Sessions: If it hurts, you don't have to nurse for long periods. A few minutes of connection is still valuable.
- Use Barrier Creams: Applying a safe nipple balm can help protect sensitive skin from irritation.
- Distraction: For older toddlers, try "nursing through a book" where you read to them to keep the session calm and focused.
Preparing for the New Baby’s Supply
While you are managing your current supply for your toddler, you can also take steps to ensure a strong start for your newborn. The final weeks of pregnancy are a great time to prepare your body and your home for the "second round" of breastfeeding.
Colostrum Harvesting
For many healthy pregnancies, healthcare providers may support "colostrum harvesting" starting around week 37. This involves hand-expressing small amounts of colostrum and freezing it in tiny syringes. This can be a great way to have a "backup" if your newborn needs a little extra help in the first few days.
Always consult your doctor or midwife before starting hand expression while pregnant. For some people at risk of preterm labor, the stimulation could potentially cause contractions.
Skin-to-Skin and the First Hour
The best thing you can do for your future milk supply happens right after birth. Plan for immediate skin-to-skin contact. This "Golden Hour" helps regulate the baby’s temperature and blood sugar. It also sends a powerful signal to your brain to move from "pregnancy mode" into "milk-making mode."
Education and Support
Knowledge is power. While breastfeeding is natural, it doesn't always come naturally. Taking a class or refreshing your knowledge on infant feeding cues can make the first week much smoother. Our online breastfeeding classes are perfect for busy parents who need a refresher from the comfort of home.
Key Takeaway: Preparing for your newborn's supply starts with education and planning for the immediate postpartum period.
Safety Considerations and When to Wean
For the vast majority of people, breastfeeding while pregnant is perfectly safe. The myth that breastfeeding causes miscarriage is generally not supported by research in healthy pregnancies. While nursing does release a small amount of oxytocin (the hormone that causes contractions), it is usually not enough to trigger labor unless your body is already prepared to give birth.
When to Consult Your Doctor
There are certain situations where your healthcare provider might recommend weaning or reducing nursing sessions:
- You are carrying multiples (twins or triplets).
- You have a history of preterm labor or late-term miscarriage.
- You are experiencing unexplained vaginal bleeding.
- You are not gaining enough weight for a healthy pregnancy.
If you decide to wean, do it slowly. Abrupt weaning can cause engorgement or even mastitis, which is the last thing you want to deal with while pregnant. Drop one feeding every few days to let your body adjust gradually.
Balancing Two Children (Tandem Nursing)
If you continue to nurse through your pregnancy, you might find yourself "tandem nursing" once the baby arrives. This means nursing both the newborn and the toddler. The amazing thing about the human body is that it will prioritize the newborn's needs, ensuring the milk has the right antibodies for the smallest baby while still providing for the older one.
Tandem nursing can help reduce sibling rivalry and provide a quiet way for you to bond with both children at once. However, it can also be physically demanding. Make sure you have a support system in place to help with household tasks so you can focus on feeding.
Creating a Support System
You cannot do this alone, and you shouldn't have to. Breastfeeding support should feel compassionate and empowering. Reach out to friends who have been through it, join a support group, or schedule a consultation with an International Board Certified Lactation Consultant (IBCLC).
At Milky Mama, we believe that every parent deserves access to expert care. Our breastfeeding help page and virtual lactation consultations can help you troubleshoot supply issues, manage nursing aversion, or create a plan for tandem nursing from the comfort of your couch.
Building Your "Village"
- Partner Support: Make sure your partner understands that you need extra rest and food.
- Childcare: If you have an older child, having someone to take them to the park for an hour can give you a much-needed nap.
- Community: Find an online community of moms who understand exactly what you are going through, or check out the Milky Mama support group on Facebook for peer encouragement.
The Role of Supplements
Many parents look to herbal supplements to help maintain their supply during pregnancy. However, you must be very careful. Some herbs that are great for lactation are not recommended during pregnancy because they could affect the uterus.
Always choose supplements that are formulated with safety in mind. Our Lady Leche™ and Pumping Queen™ supplements are designed to support milk production using high-quality ingredients. However, because every pregnancy is unique, you should always run any new supplement by your OB-GYN or midwife before taking it.
Common Lactation Ingredients
- Moringa: Often called a "superfood," it is rich in vitamins and minerals.
- Nettle: Known for being high in iron and supporting overall wellness.
- Alfalfa: Contains Vitamin K and other nutrients that support supply.
If you want a broader look at product options, the Lactation Supplements collection is a good place to compare what fits your feeding goals.

Realistic Expectations for Your Journey
It is important to remember that every body is different. Some people find that their supply stays strong throughout all nine months. Others find that their milk dries up almost immediately after the positive test. Neither of these outcomes is a failure.
Your worth as a parent is not measured in ounces. If your supply drops and your toddler decides to wean, you have still given them a wonderful gift. If you continue to nurse through the discomfort and end up tandem nursing, that is also a beautiful path.
Focus on Your Well-being
Your well-being matters too. If breastfeeding while pregnant becomes too much for your physical or mental health, it is okay to make a change. A happy, healthy parent is the best thing you can provide for your children.
Key Takeaway: Success is not a specific number of months or ounces; it is finding a balance that works for your entire family.
Summary of Action Steps
If you are looking to support your supply while expecting, keep these steps in mind:
- Prioritize Calories: Add nutrient-dense snacks like oats, protein, and healthy fats.
- Hydrate Constantly: Use electrolytes to help your body absorb water.
- Listen to Your Body: If nursing hurts, shorten the sessions or adjust the latch.
- Talk to Your Provider: Ensure your pregnancy is low-risk for continued breastfeeding.

FAQ
Will breastfeeding while pregnant take nutrients away from my unborn baby?
In a healthy pregnancy with good nutrition, breastfeeding will not deprive your unborn baby of what they need. Your body is designed to prioritize the fetus first, ensuring they get the necessary vitamins and minerals for growth. As long as you are eating enough calories and taking your prenatal vitamins, both babies can thrive.
Why did my milk change color and get thicker during my second trimester?
This is a normal transition where your mature milk begins to change back into colostrum. Colostrum is often yellow or golden in color and much thicker than mature milk because it is highly concentrated with protein and antibodies. This shift is your body’s way of preparing the perfect first food for your upcoming newborn.
Is it safe to take lactation supplements while I am pregnant?
While many lactation supplements are safe, you must be cautious because some herbs can affect the uterus. It is essential to choose products with high-quality ingredients and always consult your OB-GYN or midwife before starting any new supplement. They can help you determine if a specific product is appropriate for your individual pregnancy.
What should I do if my toddler is frustrated by the lower milk supply?
If your child is over one year old, you can offer them a small snack or a cup of water before nursing to take the edge off their hunger. If they are under a year, you should speak with your pediatrician about supplementing with expressed milk or formula. Focus on the emotional connection of nursing through cuddles and eye contact to help them through the transition.
