Introduction
When a woman gives birth, her body begins to produce milk for her baby. But the process of milk production — also known as lactation — may not happen right away; it can take time for the milk to come in. Knowing when your milk is coming in can help you plan ahead and ensure your baby is getting enough nourishment.
In this article, we’ll explore some of the signs and indicators that you can look out for to determine if your milk is coming in. We’ll also discuss possible causes of lactation issues and how to seek help if needed.
Check for Physical Signs
One of the most common signs that your milk is coming in is the appearance of leakage from your breasts. According to the Academy of Breastfeeding Medicine, “Leaking of colostrum from the nipples usually starts within 24 hours after delivery, but may occur several days before or after delivery.”
Another physical sign to be aware of is engorgement. This is when your breasts become swollen, firm, and tender due to an increase in milk production. Engorgement typically occurs two to five days after birth and can last for up to a week.
Monitor Changes in Breast Size, Firmness, and Tenderness
Another indication that your milk is coming in is a change in the size of your breasts. According to The American College of Obstetricians and Gynecologists, “As milk production increases, the breasts will enlarge and become heavier.”
You may also notice changes in the firmness and tenderness of your breasts. As your milk production increases, your breasts may feel harder, fuller, and more sensitive to touch.
Look Out for Increased Frequency of Baby’s Feeding Sessions
If you’re breastfeeding, you may start to notice that your baby is feeding more often than usual. This is because as milk production increases, babies tend to nurse more frequently in order to stimulate the production of more milk.
Track the Number of Wet Diapers Your Baby Produces Daily
Another indicator of milk production is the number of wet diapers that your baby produces each day. According to the World Health Organization, “On the first day of life, the newborn should pass meconium (the black sticky substance that filled the intestine before birth). By day three, the baby should have at least 6-8 wet diapers.”
By tracking the number of wet diapers produced each day, you can get a better idea of how much milk your baby is consuming.
Observe for Changes in Baby’s Behavior After a Feed
You can also observe your baby’s behavior after feedings to determine whether your milk is coming in. According to the La Leche League International, “After a feeding, your baby should appear content and sleepy.”

Review Any Dietary Changes You May Have Experienced
It’s also important to review any dietary changes you may have experienced during pregnancy and postpartum. Certain foods and beverages can affect lactation, so it’s important to make sure that you’re eating a balanced diet and avoiding any foods or drinks that could potentially interfere with milk production.

Consider Other Possible Causes of Lactation Issues
If you’re still having trouble determining whether your milk is coming in, there are other possible causes of lactation issues that you should consider. These include hormonal imbalances, medication side effects, stress, and dehydration.
If you’re still experiencing difficulties with lactation, it’s important to contact a lactation consultant or doctor for further guidance.
