How and When to Express Antenatal Colostrum: Step-by-Step Instructions

Expressing colostrum during pregnancy is a beneficial practice for many expectant mothers. Colostrum, often called “liquid gold” due to its rich, yellow appearance and high concentration of nutrients and antibodies, is the first milk produced by the breasts. Starting to express colostrum before birth, a practice known as antenatal colostrum harvesting, allows mothers to have a supply ready for their newborn. This is especially useful for mothers with certain health conditions, planned C-sections, or those wanting a backup of this nutrient-dense milk.

In this article, we’ll walk you through the process of antenatal colostrum expression, from the ideal time to start, step-by-step instructions for hand expression, and essential storage tips. We’ll also cover why colostrum is so beneficial for newborns, making it a valuable addition to any antenatal care plan.

Understanding Colostrum and Its Benefits

Colostrum is the first milk produced by the mammary glands and differs significantly from mature breast milk. Thick, yellowish, and nutrient-dense, it is loaded with proteins, antibodies, and growth factors that provide the baby with essential immunity and support in their first few days of life.

For many mothers, understanding the benefits of colostrum can make the practice of antenatal expression even more meaningful:

Immune Support: Colostrum contains high levels of Immunoglobulin A (IgA), which helps protect the baby’s digestive and respiratory systems.

Digestive Health: Colostrum promotes healthy digestion and acts as a mild laxative, helping the baby pass their first stool, known as meconium. This can reduce the risk of jaundice.

Blood Sugar Stabilisation: Colostrum is particularly beneficial for newborns born to mothers with gestational diabetes, as it helps stabilise blood sugar levels.

Discussing colostrum harvesting with your healthcare provider during antenatal appointments can provide further insights and ensure you’re well-prepared.

When to Start Expressing Antenatal Colostrum

The recommended time to start expressing colostrum is around 36 weeks of pregnancy. Starting at this stage allows you to develop a supply before your baby’s arrival without increasing the risk of preterm labour. However, always consult your healthcare provider before beginning, as they can provide personalised guidance based on your health.

How to Express Antenatal Colostrum: Step-by-Step Instructions

Expressing colostrum is usually done manually, without the need for a breast pump. Hand expression is gentle and effective, allowing you to collect small amounts of colostrum safely and comfortably. Here’s a simple step-by-step guide:

Step 1: Prepare Your Supplies

Before you start, make sure you have sterile syringes or small containers for storing the colostrum. Many antenatal clinics can provide these supplies, so check with your healthcare provider if needed.

Sterile Syringes or Containers: Use these to collect and store each drop of colostrum.

Clean Hands and a Comfortable Setting: Cleanliness is essential for safety, and having a comfortable space can make the process more enjoyable.

Step 2: Wash and Warm Up

Wash Your Hands: Thoroughly wash your hands with soap and water to maintain hygiene.

Warm Compress: Use a warm compress on the breasts, or take a warm shower beforehand. Warmth helps stimulate milk flow, making it easier to express colostrum.

Step 3: Massage the Breast

Gently massage your breast in a circular motion to stimulate milk production. Starting with a massage can help improve colostrum flow, making expression smoother.

Step 4: Hand Expression Technique

Position Your Fingers: Place your thumb and fingers in a “C” shape around the areola (the darker area around the nipple).

Press Back and Compress: Press gently back towards the chest and then compress towards the nipple. Release and repeat this movement rhythmically.

Collect the Colostrum: Colostrum may appear in small drops at first. Collect these drops in your sterile syringe or container.

Alternate Breasts: Once the flow slows, switch to the other breast and repeat the process.

Don’t worry if only a few drops are expressed initially—colostrum is dense and beneficial even in small quantities.

Step 5: Store Colostrum Properly

Once you’ve expressed colostrum, follow these storage guidelines:

Refrigeration: Fresh colostrum can be stored in the refrigerator for up to 48 hours.

Freezing: For longer storage, place the colostrum in the freezer. Colostrum can be frozen for up to six months. Label each container with the date it was collected.

Tips for a Successful Colostrum Expression Experience

Create a Relaxing Environment

A calm and comfortable setting can make a big difference. Some mothers find it helpful to do breathing exercises or practice antenatal yoga to help them relax before expressing. Creating a quiet, low-stress environment can improve colostrum flow.

Be Patient and Gentle

Colostrum is produced in small amounts, so don’t be discouraged if you only collect a few millilitres at a time. Every drop of colostrum is valuable and nutrient-rich.

Take Breaks if Needed

If you feel any discomfort or fatigue, take a break. Colostrum expression should never be painful. If you experience any issues, consult a healthcare provider or lactation consultant at your antenatal clinic for further assistance.

Practical Benefits of Antenatal Colostrum Harvesting

Many mothers find that antenatal colostrum harvesting offers both peace of mind and practical support for early newborn care:

Preparedness for High-Risk Situations: Mothers with diabetes or planned C-sections can have colostrum readily available in case breastfeeding is delayed.

Confidence in Breastfeeding: Practising colostrum expression can help mothers feel more confident and prepared for breastfeeding after birth.

Extra Support for Newborns: If your baby faces specific health challenges, having a supply of colostrum can ensure they receive optimal nutrition from the start.

When to Seek Antenatal Support

If you have questions about colostrum expression or experience difficulties, don’t hesitate to reach out for support. Attending antenatal classes can provide hands-on guidance and help answer any questions. Antenatal checkups are also an ideal time to discuss colostrum harvesting with your healthcare provider, who can offer tailored advice based on your needs.

Common Myths and Facts About Antenatal Colostrum Expression

Myth: Colostrum Harvesting Will Cause Labour

Fact: While nipple stimulation can cause mild contractions, expressing colostrum is generally safe if started after 36 weeks and done gently. Always discuss it with your healthcare provider to ensure it’s safe for you.

Myth: Only High-Risk Mothers Should Express Colostrum

Fact: While antenatal colostrum harvesting can be especially beneficial for mothers with certain conditions, any expectant mother may choose to harvest colostrum as a preparation step.

Myth: Colostrum Isn’t Produced Until After Birth

Fact: Many women begin producing colostrum in the second trimester, and it’s often available for expression in the third trimester. Colostrum is present and ready to support your newborn immediately after birth.

Incorporating Colostrum Harvesting into Your Antenatal Care Plan

Adding colostrum harvesting to your antenatal care plan can provide both practical support and emotional reassurance. By discussing colostrum expression during antenatal appointments and antenatal education sessions, you can gain valuable insights and confidence in this process. Many mothers find that including colostrum harvesting in their prenatal routine helps them feel better prepared for the early days of motherhood.

Antenatal colostrum harvesting is a beneficial practice for mothers looking to provide their newborns with the best nutritional start. Colostrum offers unparalleled immune and digestive support, helping stabilise blood sugar levels and promote healthy growth. Whether you’re managing a high-risk pregnancy, planning for a C-section, or simply want to be prepared, antenatal colostrum expression is a proactive way to support your baby’s early health.

Discussing colostrum expression with your healthcare provider at your antenatal checkups and attending antenatal classes can help you feel confident and prepared. By including colostrum harvesting in your prenatal care plan, you’ll be giving your baby a strong foundation for a healthy beginning.
