At what week of pregnancy is colostrum secretion usually expected?

Colostrum secretion generally begins around the 16th week of pregnancy. Colostrum is the first form of milk produced by the mammary glands during pregnancy and shortly after giving birth. It is rich in nutrients and antibodies, providing essential support to the newborn's immune system.

While the production of colostrum can start as early as the second trimester, many women may notice this secretion more distinctly around the 16th week. This timing aligns with the development of breast tissue in preparation for lactation, indicating that the body is gearing up to nourish the baby.

Understanding the process of lactation and the stages of milk production is crucial for nursing practice, as it can impact maternal support and education surrounding breastfeeding during pregnancy and after childbirth.
