Why is my Milk Supply Dropping?

Breastfeeding sometimes requires a big leap of faith. Breasts donāt have units of measure written on their sides so you can see exactly how many ounces of milk are in there! But wouldnāt that be kind of great?
The Kinds of Milk We Make
It might be helpful to know exactly how much milk is in there, but maybe not. Every person makes milk a little differently. It depends on your own anatomy and chemistry, the time of day, circumstances, and it also depends on your baby. The number of calories, carbs, and fat per serving might be different from person to person and at different times of the day. It might be different depending on what’s going on with your baby. In other words, you might say that sometimes it’s a little more like āwhole milkā and sometimes more like āskim milkā. A baby needs less whole milk to grow and more skim milk. Some babies need more or less nutrition too. Some babies are just bigger and need more calories. Some babies use every bit of what they get, while others make more waste. There is also variation in the vitamins and other nutrients in milk.
It might be that people who tend to make āwhole milkā also tend to produce less milk and the opposite can be true for people who make āskim milkā. There are so many factors to consider, and we just canāt really know. All of these are reasons why breastfeeding requires some level of trust that everything will just work out. It usually does.
So why do SO many people worry that theyāre not making enough milk?
Besides the fact that you canāt exactly SEE how much milk is in there and how much your baby is drinking, there are some things that happen in the first week after giving birth that make things even more confusing.
Early Milk
When your baby is born, your body provides colostrum. Colostrum is the first milk. Itās different from the milk that will be made a little later on. Itās extra dense and concentrated, but there is only a small amount. Your breasts probably wonāt seem much different. You wonāt see your baby taking big swallows of milk. They only get about a teaspoon at a time, but thatās all they need because their stomachs are still very small. Theyāll just eat more often at first. Itās not very dramatic, and the milk supply is not obvious.
But then, usually after about 3-5 days of feeding your baby colostrum, your body will start to change. It might be a very sudden and dramatic change. Your breasts might suddenly fill up with milk. You might be able to see and feel all of the swollen milk glands. Your breasts might get very large and firm, and you may even see popping veins. You might notice that your baby is taking big gulps of milk. You might leak a lot and even see milk spraying out of your nipples.
When Engorgement Happens
This change can be a little overwhelming. The baby might have a little trouble adjusting to so much milk and have trouble emptying both breasts. Your breasts might feel very full and uncomfortable. It can even be painful for some people. This is called primary engorgement. We have this simple guide to help you understand and manage engorgement.
Fortunately, engorgement is a temporary problem for most people. After 48-72 hours, most people will see that the milk production decreases and the baby adjusts to drinking more, and things stabilize. BUT sometimes this is unexpected and people assume there is a problem.
Going from an oversupply of milk during engorgement to a normal amount of milk can feel like a drop in milk supply. Even though this is normal, some people worry that there is not enough milk without those obvious signs of oversupply. Itās important to stay relaxed and just continue to follow your babyās lead.
You shouldnāt do a lot of overstimulation of the breasts by using a pump to extract milk when youāre engorged. You also shouldnāt need to do this AFTER the engorgement goes away because you think your supply is too low. When your baby wants to eat, offer a breast. Sometimes they want to eat a lot, and sometimes it will be less. That is also very normal. They have extra hungry days and not-so-hungry days. Your milk supply tends to keep up really well when you can just āgo with the flowā and let your babyās hunger and satiety cues lead the way. But it does take some faith and patience!
