Breasts Leaking

During your pregnancy you may be surprised to find your breasts are leaking a yellowish fluid called colostrum. That's completely normal. Leaking breasts are most common during the 3rd trimester as your body prepares for your baby. But it can happen anytime during pregnancy, or not at all. In some women, leaking only occurs during sexual stimulation or when their breasts are massaged. In other women, leaking may just happen on its own.

Colostrum is the “pre-milk” that will nourish your baby in the first days of life until your milk comes in. It may continue a few days after delivery. But as you get closer to delivery, the fluid changes to a thin, colorless liquid.

Call Doctor If:

  • Fluid leaking from your breasts has blood in it.

Step-by-Step Care:

  • Place disposable or washable nursing pads inside your bra to help soak up any fluid.
  • Reduce breast or nipple stimulation.
  • Wear a sports bra to bed.
