Background

Antenatal colostrum expression refers to the practice of hand-expressing and storing breast milk during the final weeks of pregnancy, usually beginning around 36 weeks of gestation. Initially introduced to provide an immediate supply of colostrum for newborns at risk of hypoglycemia, particularly those born to mothers with diabetes, it was also intended to reduce reliance on commercial milk formula. Over time, the practice has gained significant international visibility through clinical recommendations, maternal testimonials, and social media promotion. As a result, antenatal colostrum expression is now being extended to low-risk pregnancies despite limited population-level evidence supporting its universal application. Implications of widespread adoption: Evidence from randomized controlled trials has shown that antenatal colostrum expression is safe for women with diabetes in pregnancy and does not increase rates of preterm birth. However, these studies did not find measurable improvements in breastfeeding initiation, exclusivity, or long-term breastfeeding outcomes when compared to standard care. Reports from mothers highlight additional concerns, including prenatal mastitis, anxiety about milk supply, and pressure to collect excessive amounts of colostrum without professional supervision. For infants, the use of stored colostrum immediately after birth may contribute to overfeeding, a poor latch, and early reliance on supplemental milk. Beyond clinical outcomes, the growing commercialization of this practice risks presenting it as a maternal obligation rather than a carefully targeted intervention for selected situations.

Conclusion

Antenatal colostrum expression may provide benefits for certain high-risk pregnancies, particularly when neonatal hypoglycemia is anticipated, but current evidence does not support its routine use for all women. Its adoption should remain guided by clinician judgment and individualized prenatal counseling rather than being promoted as a universal recommendation. Until larger, well-designed studies confirm both safety and measurable improvements in breastfeeding outcomes, this practice should be considered a supportive tool for specific populations rather than a standard component of prenatal care.
