When Will My Milk Come In? What You Should Know

Many new moms who want to breastfeed are anxious to know when their milk will come in after baby is born. Here is what you need to know.

Have you heard the stories of how breastmilk comes in following birth? Tales of engorged breasts and looking like you’ve had breast augmentation when your milk comes in? Of babies with milk sprayed all over their faces as the let-down happens? While it’s true that some women have firehose breasts and extreme engorgement within a couple of days following birth, it can look quite different for many others. Some of us won’t feel any engorgement. Some will have concerns with their supply within hours after having their baby. For others, they will be confused about whether or not their milk has even come in at all! I will cover how this process happens and how to encourage your milk to come in quickly and effectively.

When Will My Milk Come In?

Let’s start with the physiological process of how our bodies make milk. Here are the different stages of lactation:1

Stages of Lactation

Mammogensis (From Puberty Until the End of the 3rd Trimester):

This is when our breast tissue grows in size and weight, starting with puberty. When we become pregnant, we grow more due to the production of estrogen and progesterone.

Lactogenesis, Stage 1 (Mid-Pregnancy to Day 2 Postpartum):

This is when our glandular tissue (where the milk is made and stored) starts actually to make the milk! This is why many of us can squeeze colostrum (or “liquid gold”) out even before our baby is born. Once our baby is born, we make colostrum until it becomes mature milk over time.

Lactogenesis Stage 2 (Day 3-Day 8 Postpartum):

This is when the colostrum changes into mature milk, and many people feel their milk “come in” with engorged, warm breasts. This is triggered by the rapid drop in progesterone levels when the placenta detaches following birth. This is why women with retained placenta products in the womb will sometimes have supply issues, as their progesterone levels are still high.

Galactopoiesis (Day 9 Until Involution):

This is when the milk is established and controlled by the autocrine system (the supply and demand system). This will not continue unless the baby (or pump) drains the breast effectively.

Involution (Average 40 Days After the Last Breastfeed):

When your child weans, your breasts go through this final process. You might find that you can squeeze out some milk for many months following weaning, though!

Pay Attention to Breast Growth and Changes

There are two questions I always ask people when taking a history. The first is, “Did you notice breast growth and changes during pregnancy?” Followed by, “Did you notice your milk come in after your baby was born?” I ask these questions because they indicate whether their body has prepared and gone through the expected physiological changes for lactation. Even if you don’t plan on breastfeeding your baby, your body will still go through these changes in breast growth and your milk coming in (unless you’re given medication to stop your milk).

If you do not have breast growth or changes during pregnancy, or you do not feel your milk come in, it is a good idea to speak with an International Board Certified Lactation Consultant (IBCLC) so you can prepare in the event you do not have enough milk to feed your baby. It is important to note here that even if you suspect your breasts have not changed much or you didn’t feel your milk come in, it does not mean you are guaranteed to need to supplement with formula! Some women will not notice much breast growth or changes. And some never feel engorged but still have enough milk. These are just indicators we look out for that *might* indicate possible challenges with milk supply.

5 Ways to Help Bring Your Milk in Quickly

It’s not just about physiology, though. It’s also about how you are feeding your baby and whether or not your baby can effectively and efficiently drain your breasts. Here are the important factors to consider to help make your milk come in quicker and establish your supply.

1. Cesarean Birth May Bring Challenges

Research shows that having a cesarean birth increases your likelihood of having breastfeeding challenges.2 However, if you have a cesarean birth, you can still do things to ensure your milk comes in as quickly as possible! The most critical first step to this following birth is simply being skin-to-skin with your baby as quickly as possible following the birth and for as long as possible. The more frequently you can be skin-to-skin, the more opportunity your baby has to breastfeed, which equals stimulation and milk removal! This, in turn, leads to more milk more quickly.

2. Skin-To-Skin Is Essential

Skin-to-skin does not just apply to those who have had cesarean births! It is the single most important thing that everyone should do as much as possible, 24/7, after the baby is born. Just let them “hang out” with your breasts as much as possible. This ensures unrestricted access to the breast, encourages more frequent feeds, and allows you to pick up on the early feeding cues they’d like to breastfeed!

3. Follow Your Baby, Not the Clock

We have all heard the term “supply and demand” regarding breastfeeding. But what does that mean in practical terms? The more you feed your baby, the more milk will be removed and the more milk you will make. If you are trying to follow a schedule you found in a book or website or trying to stretch out the time between feeds, then you risk decreasing your supply. As you stretch out the time, your breasts are filling up. As they fill up and stay full, your production slows down (so your breasts don’t explode!). This is why following your baby and feeding on demand is so important. If you’d like to breastfeed exclusively and avoid formula supplementation, feeding on demand is the best way to help this happen.

4. Make Sure Baby Has a Good Latch

If you are concerned about your baby’s latch or their ability to drain your breast well, make sure to seek help ASAP! For your baby to encourage your milk to come in, increase in volume, and maintain your supply, they must have optimal milk transfer. In other words, you need to ensure they can effectively and efficiently drain your breasts so you make more throughout the 24-hour period. Even if someone tells you the latch “looks good,” it doesn’t matter. If it doesn’t feel right or you know something is wrong, seek another opinion! How the latch looks to someone else means nothing.

5. Determine If Pumping Would Help

If your milk has not come in or you have a low supply, the important thing is to have frequent effective milk removal, whether from your baby or a breast pump. If your baby can drain the breast well, then do this with your baby. If your baby cannot remove the milk well (or easily), or you have to miss feeds with your baby (due to separation), you’ll need to use a pump. A double electric hospital-grade breast pump usually leads to the most effective milk removal.

Remember, the best way to establish and maintain supply is to be skin-to-skin as much as possible in the early weeks and follow your baby, not the clock. If you are concerned that your milk is not coming in as soon as you’d like, seek help from a volunteer breastfeeding counselor or IBCLC quickly.
