Yes, your nipples might leak during pregnancy. Here's the science (and the sanity check)

You're getting the baby's nursery together – that crib isn't going to make itself! – when you look down and see two wet spots on your shirt. The baby's not even here yet! What gives?

If you're a first-time mom, you may be surprised to know that's not breast milk. It's something called colostrum, and it's totally normal to be leaking a bit. Here's what to know, and when to talk to your healthcare provider about it.





Key Takeaways

  • Colostrum is a high-protein liquid, clear or yellowish and cloudy, that your body produces before milk.
  • Your body begins making colostrum in your second trimester, and while it's possible to leak then, it's most common toward the end of your third trimester.
  • It's completely normal to leak (or not!) in the weeks before you give birth. Consider using nipple pads so it doesn't get on your clothes.

What is colostrum?

Colostrum is a high-protein, antibody-rich liquid that your body produces for your newborn. Because it's the perfect first food for your baby, people also refer to it as "liquid gold." Colostrum:

  • Provides ideal newborn nutrition.
  • Protects against infections.
  • Is easily digested.
  • Has a laxative effect that helps clear meconium from an infant's gastrointestinal tract (which in turn reduces the risk of jaundice).
  • Helps establish a healthy gut microbiome.
