Why do I have leaky breasts in my third trimester?

Not only are leaky breasts possible in the third trimester of pregnancy, but it is possible they could start leaking even sooner. This is because your body has already started releasing the hormones that trigger breast milk production. The fluid you are leaking is actually the pre-milk called colostrum. In fact, your body begins colostrum production as early as three to four months into pregnancy.

Colostrum is the milk produced by your breasts for the first few days of your baby’s life. This milk has different byproducts and nutrients than normal breast milk and is not has heavy since your baby will not require as much to eat the first few days. Once your milk truly ‘comes in’, then the colostrum will be no more.

Colostrum is full of antibodies and proteins and is great for protecting your newborn from infections. It is easy for your baby to digest and makes the perfect first food for your infant.

So, having leaky breasts during any point in pregnancy is simply a good sign that your breasts, and milk production, are running smoothly. If it becomes a problem, you’ll just have to begin investing in those nursing pads earlier than you thought.
