Finding out you are pregnant while still breastfeeding an older child is a major milestone. It is a time filled with excitement, but it also brings a unique set of challenges for your body. Many mothers notice their milk supply begins to dip shortly after that positive pregnancy test. You might feel a mix of emotions if your nursing journey feels like it is changing before you are ready.
At Milky Mama, we understand that you want to provide the best for both your growing bump and your breastfeeding child. This post will explore why supply changes during pregnancy and how you can support your milk production. We will cover nutrition, hydration, and gentle techniques to help you navigate this transition. We want to empower you with the tools to continue your breastfeeding journey for as long as it feels right for your family.
Our goal is to help you understand the biological shifts happening in your body and provide actionable steps to maintain your wellness. While pregnancy hormones are powerful, there are many ways to support your lactation and overall health during these nine months. For a deeper look at the science behind this season, our guide to supporting milk supply while pregnant is a helpful next step.
It is very common for milk supply to decrease during pregnancy. In fact, research suggests that as many as 70% of breastfeeding mothers experience a significant drop in volume. This usually happens around the end of the first trimester or the beginning of the second trimester.
The primary reason for this change is hormonal. When you are pregnant, your body produces high levels of estrogen and progesterone. Progesterone is essential for maintaining a healthy pregnancy, but it is also a natural milk inhibitor. It works to prevent your body from making large amounts of milk until after the baby is born.
You might also notice a change in the taste and consistency of your milk. Around the fourth or fifth month, your milk transitions back into colostrum. Colostrum is the thick, yellow "first milk" that is very high in antibodies and protein. It often tastes saltier and less sweet than mature milk. Some older children may react to this change by nursing less or even weaning on their own. If you want a fuller explanation of this shift, our breastfeeding during pregnancy guide covers it in more detail.
Key Takeaway: A drop in milk supply during pregnancy is a normal biological response to rising progesterone levels. This hormone prioritizes the needs of the developing pregnancy.
Your body is currently performing two very demanding tasks. It is growing a new human life and producing milk for another. This "double workload" means your nutritional needs are significantly higher than usual. If you are looking for how to increase milk supply during pregnancy, start with your plate.
A breastfeeding mother typically needs about 500 extra calories per day. A pregnant mother needs about 300 extra calories by the second trimester. When you combine these, you may need roughly 800 additional calories every day to maintain your energy and milk production.
Focus on nutrient-dense foods rather than empty calories. If you struggle with morning sickness, try to eat small, frequent meals. High-protein snacks can help stabilize your blood sugar and provide the building blocks your body needs for lactation.
Certain nutrients are vital during this overlap period.
Our Emergency Lactation Brownies are a popular choice for busy moms. They are made with ingredients like oats and flaxseed, which have been used for generations to support milk supply. These treats provide a convenient way to get those extra calories while supporting your lactation goals. If you want to browse more options, the lactation snacks collection is a good place to start.
Staying hydrated is one of the simplest ways to support your milk supply. When you are pregnant, your blood volume increases by nearly 50%. This means your body requires much more water than usual to maintain your own health, the amniotic fluid, and your milk volume.
Dehydration can lead to a quick drop in milk production. It can also cause Braxton Hicks contractions, which are "practice" tightenings of the uterus. Aim to drink enough water so that your urine is consistently pale yellow.
If plain water feels boring, or if pregnancy-related nausea makes it hard to drink, try adding electrolytes. Our Pumpin' Punchโข or Lactation Drink Mixes are great options. These drinks provide hydration along with supportive ingredients to help you feel your best.
A galactagogue is a substanceโusually a food or herbโthat may help increase milk supply. However, not all herbs that are safe for breastfeeding are safe for pregnancy. This is a very important distinction to make.
Many common lactation supplements contain ingredients that could potentially cause uterine contractions. You must be cautious and always consult with your healthcare provider before starting any new supplement.
We offer several products designed with safety and efficacy in mind. For example, our Lady Lecheโข and Pumping Queenโข capsules are formulated for lactating moms who want targeted support. Many mothers find that herbal support helps them maintain a baseline supply even when hormones are working against them. You can also explore the lactation supplements collection to compare options.
What to do next:
- Check your current supplements for any restricted ingredients.
- Consult your OB-GYN or midwife about any herbs you plan to take.
- Focus on food-based support like oats, brewer's yeast, and flaxseed.
Milk production is largely a "supply and demand" system. The more milk that is removed from the breast, the more your body is signaled to produce. During pregnancy, this rule still applies, though the "demand" signal has to compete with pregnancy hormones.
If your older child is still nursing frequently, they are providing the stimulation your body needs. If they are nursing less because of the change in taste or supply, you may want to use a breast pump for a few minutes after a feed. This extra stimulation can help signal to your body that the milk is still needed.
Many pregnant women experience nipple soreness due to increased levels of estrogen and progesterone. This can make frequent nursing or pumping uncomfortable. To manage this:
If nursing becomes painful, it is okay to set boundaries. You can limit nursing sessions to a certain length of time or use distraction techniques with your older child. Your comfort and mental well-being are just as important as the milk supply.
If you find that your milk flow has slowed down, breast compression can help. This technique involves gently squeezing the breast tissue while your child is nursing or while you are pumping.
This helps to:
To perform a compression, place your hand in a "C" shape around your breast. Squeeze gently but firmly without causing pain. Hold the squeeze until the child stops swallowing, then release and move your hand to a different spot. This simple physical action can help you maximize the amount of milk your child receives during each session.
It is no secret that stress is a "supply killer." When you are stressed, your body produces cortisol. High levels of cortisol can interfere with the let-down reflex. The let-down reflex is the hormonal response that causes milk to flow from the ducts to the nipple.
Furthermore, fatigue is a major factor during pregnancy. Growing a baby is exhausting, and exhaustion can lead to a decrease in milk volume. While "sleep when the baby sleeps" is often easier said than done, it is vital to prioritize rest.
For some mothers, the supply drop is so significant that they find themselves "dry nursing." This means the child is sucking at the breast, but very little to no milk is being produced.
Dry nursing can be a very positive experience for many families. It provides comfort, security, and a sense of routine for the older child. It also keeps the "demand" signal active for when your milk supply increases again after birth.
However, if your child is under one year old, they still rely on milk as their primary source of nutrition. If your supply drops during this time, you must work closely with a pediatrician to ensure your child is getting enough calories from other sources, such as formula or donor milk.
Key Takeaway: Breastfeeding is about more than just nutrition. It is a relationship. If dry nursing works for you and your child, it is a valid way to maintain your bond.
Tandem nursing is the practice of breastfeeding two or more children of different ages at the same time. Many mothers choose to continue nursing through pregnancy so they can tandem nurse after the new baby arrives.
One of the benefits of tandem nursing is that the older child can help manage the increased milk supply that comes in after birth (often called "the engorgement phase"). Having an experienced "nurser" can help prevent clogged ducts and keep you comfortable.
It also helps the older sibling feel connected to the new baby. Instead of feeling like they are being replaced, they see that there is enough roomโand enough milkโfor everyone. If you plan to tandem nurse, continue to focus on your nutrition and hydration now to build a strong foundation for the future. If you want more structured education, the Breastfeeding 101 course can be a useful resource.
While most supply changes during pregnancy are normal, it is always a good idea to have a support system in place. If you are worried about your child's weight gain or if you are experiencing significant pain, reach out for help.

Increasing milk supply during pregnancy is a unique challenge because you are working alongside powerful hormonal shifts. While you may not be able to completely override the effects of progesterone, you can certainly support your body through nutrition, hydration, and frequent stimulation. Every drop counts, and the effort you are putting in to nourish your children is remarkable.
Remember to be kind to yourself. Your body is doing incredible work by sustaining two lives at once. Whether your supply stays steady or decreases, you are still providing your child with comfort and love.

Yes, you can use a breast pump to provide extra stimulation, which may help maintain your supply. However, pregnancy hormones often limit the amount of milk you can produce, so you may not see the same results as you would when not pregnant. If you have a high-risk pregnancy or a history of preterm labor, consult your doctor before using a pump, as nipple stimulation can sometimes cause uterine contractions.
Many of our products are formulated with ingredients that are generally considered safe for breastfeeding, but pregnancy requires extra caution. We recommend always showing the ingredient list of any supplement, including Lady Lecheโข, to your OB-GYN or midwife before use.
No, your body does not have a "finite" amount of colostrum. Your breasts will continue to produce colostrum throughout the end of your pregnancy and in the days following birth. While your older child may consume some of the colostrum produced now, your body will continue to make more to ensure your newborn has everything they need when they arrive.
Around the middle of your pregnancy, your milk begins to change back into colostrum. This milk is much higher in sodium and protein and lower in lactose than mature milk, which gives it a saltier, less sweet taste. These changes are completely normal, though they may cause some older children to nurse less frequently or decide to wean.
