  • Taiwanese obstetrician Dr. Su Yi-ning clarifies that antenatal colostrum harvesting is not a superstition but not a mandatory practice for all pregnant women.
  • He explains that colostrum production begins in mid-to-late pregnancy and contains vital immune components, with harvesting typically recommended after 36-37 weeks gestation under medical guidance.
  • While beneficial for high-risk groups like diabetic mothers, current research suggests it's not necessary for all low-risk pregnancies, emphasizing frequent infant suckling post-birth as the primary method for establishing lactation.

Antenatal colostrum harvesting, the practice of collecting breast milk before birth, is not a superstition but also not a requirement for every pregnant woman, according to Taiwanese obstetrician Dr. Su Yi-ning. He clarified that the fluid secreted by the breasts during pregnancy is indeed colostrum, containing essential immune components like immunoglobulins and lactoferrin.

Dr. Su explained that while many believe colostrum only appears after birth, the breasts actually begin producing it in the mid-to-late stages of pregnancy. The significant hormonal shift after placental delivery triggers the large-scale production of milk. The collected pre-birth colostrum, even if in small amounts, can be valuable.

The practice of antenatal colostrum harvesting has gained traction in countries like Australia and the UK. The primary idea is to have a supply of colostrum ready for the baby if immediate supplementation is needed, especially for mothers establishing lactation. This is particularly relevant for diabetic pregnant women, whose babies may have a higher risk of hypoglycemia, allowing for early breast milk supplementation.

Yes.

— Dr. Su Yi-ningResponding to whether the fluid secreted by the breasts during pregnancy is considered colostrum.

However, Dr. Su cautioned against indiscriminate breast stimulation, as it can promote oxytocin release, potentially causing uterine contractions. Current recommendations suggest considering harvesting only after 36 to 37 weeks of gestation and with a doctor's approval. Certain conditions, such as placenta previa or antepartum bleeding, require careful discussion with an obstetrician before attempting any harvesting.

A 2020 Cochrane Review indicated that research on the topic is limited, with insufficient evidence to support routine antenatal colostrum harvesting for all pregnant women. While it can be a valuable preparation for high-risk mothers under medical supervision, it is not considered essential for low-risk pregnancies, where frequent infant suckling after birth remains the most crucial factor for establishing lactation.

It is not a superstition, but it is not a homework that everyone must complete.
