Historically, colostrum was expressed by women mid- to late-pregnancy with the intent to avoid engorgement and breast trauma in the postnatal period, but it was not stored for use after birth.

In this episode, we will “milk” the data- including a RCT from 2023 – and present some key points to consider about what it is and what it isn’t.
