Storing Antenatal Colostrum: How to Prepare for Baby’s First Feeds

Collecting and storing antenatal colostrum has become a valuable practice for expectant mothers. Colostrum, often called “liquid gold,” is the nutrient-dense first milk produced by the breasts. It is packed with essential antibodies, proteins, and nutrients that offer newborns a powerful immune boost and support for their digestive system from the very first feed. Storing colostrum allows you to have this beneficial resource readily available, especially if breastfeeding is delayed after birth due to medical procedures or other reasons.

In this article, we’ll cover everything you need to know about storing antenatal colostrum, including when to start expressing, how to safely store it, and why it can be an essential part of your antenatal care plan.

What is Antenatal Colostrum?

Antenatal colostrum refers to the first milk that is produced during pregnancy, generally starting around the third trimester. Colostrum is different from mature breast milk because it is thicker and richer in nutrients and antibodies, making it ideal for supporting newborn immunity and digestion. Even in small amounts, colostrum provides significant health benefits, helping protect your baby against infections, stabilise blood sugar levels, and promote healthy growth.

For many mothers, antenatal colostrum harvesting allows them to be prepared for their baby’s first feeds, regardless of any potential challenges with breastfeeding. Discussing colostrum expression and storage with your healthcare provider during antenatal appointments can help you feel confident and informed about the process.

Benefits of Storing Antenatal Colostrum

Immune System Support

Colostrum contains high levels of antibodies, particularly Immunoglobulin A (IgA), which helps protect your baby’s digestive and respiratory systems. Since newborns are vulnerable to infections, especially in the first few days of life, having stored colostrum provides an extra layer of protection.

Stabilises Blood Sugar Levels

For babies born to mothers with gestational diabetes or other metabolic concerns, colostrum is particularly beneficial. Its unique composition helps stabilise blood sugar levels naturally, providing newborns with balanced energy without causing glucose spikes.

Supports Digestive Health

Colostrum’s natural laxative effect assists newborns in passing their first stool, known as meconium. This process also helps clear bilirubin, reducing the risk of jaundice. The nutrients in colostrum support the development of a healthy gut and foster beneficial bacteria in the baby’s digestive system.

When to Start Collecting Antenatal Colostrum

It’s generally recommended to start expressing colostrum around 36 weeks of pregnancy, although every mother and pregnancy is unique. Before starting, always consult your healthcare provider to ensure that colostrum collection is safe for you, particularly if you have a high-risk pregnancy.

How to Express and Store Antenatal Colostrum: Step-by-Step Guide

Expressing colostrum by hand is a gentle and effective method for collecting this valuable milk. Here’s a detailed guide to help you start.

Step 1: Gather Your Supplies

You’ll need sterile syringes or small storage containers to collect and store colostrum. These are often available from your antenatal clinic or local pharmacy. Label each syringe or container with the date of collection for easy tracking.

Step 2: Wash and Prepare

Clean Your Hands: Proper hygiene is essential to prevent contamination. Wash your hands thoroughly with soap and warm water.

Warm Compress: Apply a warm compress to the breast or take a warm shower beforehand. The warmth helps stimulate milk flow, making colostrum easier to express.

Step 3: Massage the Breast

Gently massaging the breast in circular motions can encourage colostrum flow. Start from the outer edges of the breast and gradually move towards the nipple.

Step 4: Hand-Expression Technique

Position Your Fingers: Form a “C” shape with your thumb and forefinger around the areola (the darker area around the nipple).

Press and Compress: Gently press back toward your chest, then compress towards the nipple. This rhythmic motion can help express colostrum in small droplets.

Collect in a Sterile Syringe or Container: Use your sterile container to collect the drops. Don’t worry if only a few drops are expressed initially—colostrum is highly concentrated, and even small amounts are beneficial.

Step 5: Store Safely

Once collected, follow these storage guidelines to keep colostrum safe for your baby.

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

Freezing: For longer storage, freeze colostrum. It can remain in the freezer for up to six months. Label each container with the date it was expressed for easy reference.

Thawing: Thaw frozen colostrum in the refrigerator or by running it under warm water. Avoid microwaving, as it can damage the antibodies in colostrum.

Why Antenatal Colostrum Collection is Helpful for New Moms

Preparation and Peace of Mind

Knowing that you have stored colostrum ready for your baby’s first feeds provides reassurance, especially for mothers with high-risk pregnancies or those planning for a C-section. It’s a proactive way to ensure your baby receives the nutritional support they need from day one.

Familiarity with Breastfeeding

Practising colostrum expression allows you to get comfortable with hand expression, which can be a helpful skill if your baby has trouble latching initially. This experience can also build your confidence, making you feel more prepared and comfortable with breastfeeding.

Extra Support for Challenging Situations

In cases where immediate breastfeeding may be challenging—such as in the case of multiples, premature birth, or other medical needs—having stored colostrum ensures that your baby receives optimal nutrition even if direct breastfeeding is delayed.

Tips for a Successful Colostrum Collection Experience

Create a Calm Environment

Many mothers find that a calm, relaxing environment helps with colostrum expression. Practising relaxation techniques or even antenatal yoga can help you feel more at ease. Gentle breathing exercises and finding a comfortable position can make the process smoother.

Take Your Time

Colostrum expression should be a gentle and unhurried process. Taking breaks if needed can help prevent stress. Colostrum is produced in small amounts, and even a few millilitres are enough to provide significant health benefits to your newborn.

Label and Organise Your Storage

Proper labelling with dates allows you to keep track of the colostrum you’ve stored, ensuring you use the oldest supplies first. An organised storage system will make it easier to access the colostrum when needed.

Common Myths About Storing Antenatal Colostrum

Myth: Expressing Colostrum Before Birth Can Trigger Labour

Fact: While nipple stimulation can sometimes cause mild contractions, colostrum expression is generally safe when done gently after 36 weeks of pregnancy. However, always consult your healthcare provider to confirm that it’s safe for your situation.

Myth: Colostrum Can Only Be Collected After Birth

Fact: Colostrum is produced during late pregnancy, often starting in the second trimester. Many mothers can safely collect colostrum in the third trimester, especially with guidance from their healthcare provider.

Myth: Expressing Colostrum is Only for High-Risk Pregnancies

Fact: While colostrum harvesting is particularly beneficial for mothers with certain conditions, any expectant mother can choose to collect colostrum as part of her prenatal care routine. It’s a helpful practice for those who want to prepare for the early days of feeding.

Antenatal Education and Support for Colostrum Harvesting

Attending antenatal classes or speaking with a healthcare provider during antenatal checkups can provide helpful insights into colostrum expression and storage. Antenatal education sessions often cover topics such as breastfeeding, newborn nutrition, and the benefits of colostrum, helping you feel more prepared.

Classes also offer the chance to learn about proper storage and hand-expression techniques, and they allow you to ask questions and gain confidence. Knowing you’re prepared for your baby’s first feeds can be empowering and reassuring.

Adding Colostrum Harvesting to Your Antenatal Care Plan

Integrating colostrum collection into your antenatal care plan can give you a valuable resource for your baby’s early nutrition. Discussing it with your healthcare provider at your antenatal clinic ensures you have the right guidance and support to begin safely. Many mothers find that including colostrum harvesting as part of their routine gives them peace of mind and provides a practical solution for their baby’s early feeding needs.

Conclusion

Storing antenatal colostrum is a proactive step that provides essential nutrients and immune support for your newborn. Colostrum’s unique properties make it a powerful first food for babies, offering immune protection, stabilising blood sugar, and promoting digestive health. For mothers, antenatal colostrum expression offers reassurance, especially in cases where immediate breastfeeding might be challenging.

Including colostrum harvesting in your antenatal care plan allows you to be prepared for your baby’s first feeds, ensuring that you have a supply ready when your baby arrives.
