Discovering your breasts are leaking colostrum before your baby arrives can be a surprising, and sometimes messy, part of late pregnancy for some. This visible sign of your body's preparation for feeding is a common experience, and understanding it can bring a sense of clarity and calm.
What it is
Colostrum is the nutrient-rich, early breast milk your body produces, and it can begin to leak from the nipples as early as 16–20 weeks of pregnancy. While it can start earlier, it's more commonly noticed in the third trimester. It's important to know that whether you experience leaking or not, your breasts are producing colostrum throughout your pregnancy. This is a normal and expected part of the process for some, and conversely, not leaking is also perfectly normal. Neither experience predicts your postpartum milk supply, so there's no need for concern if you don't see any leakage.
What it tends to feel like
For those who experience it, colostrum leaking might feel like a sudden wetness on your clothing or a slight stickiness on your nipples. It's often a mild sensation, but the unexpected dampness can sometimes be startling. You might notice it more at certain times of day, or if your breasts are stimulated. Managing this can be quite straightforward; many find that using breast pads, available in both washable and disposable options, can help absorb any leakage and keep you feeling comfortable and dry. Allowing your nipples to air-dry between uses of pads can also help prevent any potential irritation.
