Does Harvesting Colostrum Have The Same Effect on Your Body as Breastfeeding? Insights on Antenatal Practices

When it comes to antenatal care, there are numerous aspects of pregnancy that are carefully managed in preparation for childbirth. One of the most important, yet often overlooked, aspects is colostrum harvesting. Colostrum, the first milk produced by the body after childbirth, is often referred to as “liquid gold” because of its nutrient-rich properties. In recent years, there has been a growing interest in harvesting colostrum antenatally — that is, expressing and collecting it before the baby is born. For many, this practice is seen as a proactive step in ensuring that their baby has access to this vital first milk, especially in the event of complications or early delivery. But does harvesting colostrum have the same effect on your body as breastfeeding? While the two processes share similarities, there are important differences in how the body responds to colostrum harvesting compared to actual breastfeeding. This article delves into the physiological effects of both practices, their potential benefits, and the role of antenatal support in educating expectant mothers about the options available.

What is Colostrum and Why Is It Important?

Before exploring the effects of harvesting colostrum, it’s essential to understand what colostrum is and why it is so important. Colostrum is the thick, yellowish fluid produced by the breasts during pregnancy and just after birth. This early milk is packed with nutrients, antibodies, and other bioactive compounds that help protect and nourish a newborn in the first few days of life. It plays a crucial role in the early development of the baby’s immune system and helps establish the gut microbiome, which is essential for long-term health. Unlike mature breast milk, which contains higher amounts of fat and lactose, colostrum is richer in protein and low in fat. This makes it ideal for a newborn’s developing digestive system. For this reason, many healthcare providers recommend exclusive breastfeeding, where possible, for the first few months of life to ensure that the baby receives all the necessary nutrients and immune support.

Harvesting Colostrum During Pregnancy

Antenatal care encompasses a variety of practices and strategies designed to ensure the health and well-being of both the mother and the baby during pregnancy. As part of this care, colostrum harvesting is increasingly being recommended for women who are at risk of complications such as preterm labour, gestational diabetes, or difficulties with breastfeeding. Colostrum harvesting involves manually expressing colostrum from the breasts before the baby is born. This can be done using a breast pump or by hand, and the expressed colostrum is then stored in small syringes to be used after birth if needed. This practice can also benefit women who are concerned about not being able to produce enough milk after delivery or who are hoping to ensure that their baby has colostrum even if breastfeeding is delayed.

The Physiological Differences Between Colostrum Harvesting and Breastfeeding

While both colostrum harvesting and breastfeeding are connected to lactation, they involve different physiological processes. Antenatal care often includes guidance on how to manage these processes to ensure the best outcome for both the mother and the baby.

1. Hormonal Changes in the Body

Breastfeeding and colostrum harvesting both trigger hormonal responses in the body, but the effects are different in terms of intensity and timing.

• Breastfeeding stimulates the release of oxytocin, a hormone responsible for milk ejection and uterine contractions. The act of breastfeeding encourages the production of more milk, including mature milk, and continues to stimulate the body to produce milk for the duration of breastfeeding.
• Colostrum harvesting, on the other hand, generally occurs before the onset of breastfeeding. While it also triggers the release of oxytocin and prolactin, the hormonal effects are usually less pronounced because it is typically done in small quantities and the body is not yet fully engaged in the breastfeeding process.

2. Milk Production and Volume

Breastfeeding results in a gradual increase in milk production. After the baby is born, the body begins to produce more milk due to the regular stimulation of the breasts. In contrast, colostrum harvesting is typically done in the weeks leading up to birth and results in the production of only small amounts of colostrum. This limited volume is often enough to ensure that a mother has some colostrum available after birth but is not the same as the regular and sustained milk production seen with breastfeeding. It is important to note that colostrum harvested during pregnancy is not intended to replace breastfeeding but to ensure that the baby has access to this early milk in case of complications.

3. Impact on Uterine Activity

One of the more significant concerns regarding colostrum harvesting is the potential for premature labour. Stimulating the breasts and releasing oxytocin through colostrum harvesting can, in some cases, cause mild uterine contractions. This is why many healthcare providers recommend avoiding colostrum harvesting before 37 weeks of pregnancy unless there is a medical need or specific reason to do so. In contrast, breastfeeding after delivery has a much stronger uterine contraction effect, as the body is recovering from childbirth and trying to return to its pre-pregnancy state. Prenatal care typically includes guidance on when and how to harvest colostrum, with most experts recommending doing so after 36 weeks to avoid preterm labour.

Benefits of Colostrum Harvesting During Pregnancy

For many mothers, colostrum harvesting can be a valuable part of their antenatal care. There are several key benefits to this practice:

1. Ensuring Early Nutrition for the Baby

One of the main reasons to harvest colostrum during pregnancy is to ensure that the baby has access to this important first milk, even if there are complications. For example, if the baby is born prematurely, or if there are breastfeeding difficulties, having a supply of colostrum on hand can be vital. Colostrum is rich in antibodies, which help protect the newborn against infections during their first few days of life.

2. Increasing Confidence and Reducing Stress

Expectant mothers who are worried about breastfeeding can feel more confident knowing that they have already expressed some colostrum. This can reduce anxiety, especially if there are concerns about the baby’s ability to latch or if the mother faces physical challenges during the early days of breastfeeding.

3. Supporting Babies with Special Needs

In some cases, babies may require additional support in the first few days of life, especially if they are born with medical conditions or require specialised care. Having harvested colostrum ensures that the baby can be fed with their mother’s milk, even if the breastfeeding process is delayed due to medical intervention.

Risks and Considerations of Colostrum Harvesting

While there are many benefits to colostrum harvesting, there are some risks and considerations that should be taken into account.

• Preterm Labour: As previously mentioned, stimulating the breasts to express colostrum can cause uterine contractions, which may trigger preterm labour. For this reason, it is crucial to work closely with an antenatal clinic to ensure that colostrum harvesting is done safely and at the appropriate time.
• Infection Risk: Although rare, there is a slight risk of infection during the colostrum harvesting process. Proper hygiene is essential when expressing and storing colostrum to prevent contamination.
• Emotional Stress: For some mothers, the pressure to express colostrum can cause emotional stress, especially if they are unable to collect much or if they are concerned about their milk supply. It’s important to remember that colostrum harvesting is not an essential part of antenatal care, and many mothers are able to successfully breastfeed without ever needing to harvest colostrum beforehand.

How Does Colostrum Harvesting Compare to Breastfeeding?

While colostrum harvesting and breastfeeding share similar physiological processes, such as the release of oxytocin and prolactin, they differ in terms of timing, intensity, and volume of milk produced. Harvesting colostrum during pregnancy is a proactive step that ensures the baby receives this critical first milk in case of complications, while breastfeeding is a natural process that involves regular milk production and emotional bonding between mother and child. Both practices offer unique benefits, and antenatal support is crucial in helping expectant parents make informed decisions about the best approach for their individual needs. Some mothers may find that colostrum harvesting provides peace of mind, while others may prefer to wait until after birth to begin breastfeeding. In conclusion, harvesting colostrum during pregnancy can be a beneficial practice for some women, but it does not have the same effect on the body as breastfeeding. While both practices involve the release of key hormones that support milk production and maternal bonding, the effects of colostrum harvesting are typically less intense and are performed in smaller quantities compared to breastfeeding. If you are considering colostrum harvesting as part of your antenatal care, it is important to speak with your healthcare provider to ensure that it is done safely and effectively. Antenatal checkups and antenatal classes are an excellent way to gain more information and receive the antenatal support needed to make informed choices that are right for you and your baby.
