How to Store Colostrum: The Ultimate Guide for Breastfeeding Moms

Are you a soon-to-be mother who would want to know about colostrum and how to store it until the arrival of your baby? Colostrum is the thick, rich milk that is expressed within the first days of giving birth and serves especially as a superfood to the newborn. Understanding how to store colostrum provides you with a convenient reserve of this 'liquid gold' for your baby, offering both peace of mind and a valuable nutritional resource. In this article, we'll walk you through all that needs to be known about the storage of colostrum—from the type of container for storage to the thawing and feeding of this liquid gold to your precious baby.

What Is Colostrum?

Colostrum is the first form of milk that your body, from pregnancy through those early days following birth, will develop. It is often called "liquid gold" since it is thick, yellow, and just so full of nutrients and cold-fighting compounds.

Colostrum contains proteins, vitamins, minerals, and antibodies that will keep your newborn baby safe from infection and certain diseases. It also contains factors that stimulate growth, which help your baby's digestive system and other important organs mature.

Although colostrum is produced in small amounts, a little goes a long way. The small size of your baby's stomach can only hold about a teaspoon of liquid at any one time, and the concentrated nature of colostrum ensures they get all the vital components they need in these small servings.

How to Store Colostrum

Proper colostrum storage is crucial to ensure that your expressed colostrum remains safe and retains its valuable properties for your baby. Let's explore the best methods and containers for storing colostrum, as well as its shelf life under various conditions.

What do I store my colostrum in?

For storing colostrum, a 1ml syringe is your go-to container. It's easy to collect every precious drop of colostrum when you hand express – either pull it up directly into the syringe or use a sterile teaspoon and then transfer it to the syringe. This method is popular because it's efficient; you don't waste any colostrum, and you can feed your baby straight from the collection syringe.

For an eco-friendly and practical choice, consider the Momcozy Colostrum Reusable Breast Milk Collector. This nifty device not only has a precise 5ml capacity for optimal collection but is also BPA-free, ensuring the utmost safety for your little one. It's easy to clean and a brilliant solution for busy new moms.

Here's how to do it:

1. Begin with thoroughly washed hands to maintain cleanliness. Colostrum is naturally germ-free, so you don't need to sterilize it yourself.

2. When hand expressing, aim to collect the colostrum in the syringe or sterile teaspoon directly.

3. If you're using the Momcozy Collector, simply express into its 5ml capacity compartment, which is especially designed to avoid spills and save every drop.

4. Should you opt for a teaspoon, after collecting, gently transfer the colostrum into the syringe, taking care to avoid introducing air bubbles.syringes

5. Once collected, cap the syringe or the collector tightly, and label it with the current date and time of expression.

6. For additional hygiene, place the capped syringe or collector inside a sealed plastic bag.

7. Finally, store your colostrum in the refrigerator or freezer in accordance with safe milk storage practices.

Your midwife might provide syringes at no cost, but if not, you can purchase them online. Just make sure they come with caps or lids to maintain sterility.

How to Store Colostrum Without a Syringe or a Colostrum Collector

If syringes are not available, you can also store colostrum in clean, sterile food-grade containers like glass jars or BPA-free plastic containers with tight-fitting lids. Make sure to label the containers with the date and time of expression and store them in the fridge or freezer.

Another option is to use breastmilk storage bags, which are specially designed to store expressed breastmilk. These bags are pre-sterilized, leak-proof, and can be labeled easily. However, keep in mind that it may be more challenging to feed your baby directly from these bags compared to syringes.

Can I freeze colostrum?

Yes, you can freeze colostrum for future use. Freezing is a great option if you plan on expressing colostrum quite a bit before your due date, or if you express more colostrum than you think you will be able to use within a few days.

To freeze colostrum:

• Place it in sterile syringes or containers, allowing room for the expansion of fluid when freezing.
• Label the syringes or containers with the date and time of expression.
• Put them into a sealed plastic bag to prevent contamination and freezer burn.
• Store the colostrum at the back of the freezer, as it will have more constant temperatures.

How Long Does Colostrum Last?

The shelf life of colostrum depends on the colostrum storage method you choose:

• Room temperature: Colostrum is safe to be stored at room temperature, up to 77°F (25°C), but for no more than 4 hours.
• Refrigerator: Colostrum can safely be stored in the refrigerator at 40°F or 4°C for up to 4 days.
• Freezer: Colostrum can be frozen at 0°F or -18°C for up to 6 months. However, it's best to use frozen colostrum within 3-4 months for optimal quality.

Always check any stored colostrum before giving it to your baby. If it smells sour or has become discolored, then it is best to discard it and use a fresh batch.

How to Transport Your Colostrum to Hospital

When it's time to head to the hospital for your baby's birth, you'll want to ensure that your carefully stored colostrum makes the journey safely. Here are some tips for transporting your colostrum:

• Use a cooler bag: Place your colostrum syringes or containers in a clean, insulated cooler bag with ice packs to keep them cold during transport. This is especially important if you have a long journey to the hospital or if the weather is warm.
• Keep colostrum separate: Make sure your colostrum is stored in a separate bag or compartment within your hospital bag to avoid contamination from other items.
• Label everything clearly: Ensure that each syringe or container is labeled with the date and time of expression. You can also include your name and your baby's name (if known) to avoid any mix-ups at the hospital.
• Inform hospital staff: Upon arrival at the hospital, let the staff know that you have brought expressed colostrum with you. They will store it in the appropriate refrigerator or freezer and ensure it's readily available when your baby needs it.
• Use a portable cooler for long trips: If you have a lengthy journey to the hospital, consider using a portable cooler that plugs into your car's power outlet. This will help maintain a consistent temperature and keep your colostrum fresh during the trip.

If you're unsure about how to transport your colostrum or have any specific concerns, don't hesitate to reach out to your healthcare provider or the hospital staff for guidance. They will be happy to assist you in ensuring that your colostrum is transported safely and is available for your baby when needed.

How to Thaw Colostrum Syringe or Collector

When it's time to feed your baby with your frozen colostrum, it's essential to thaw it safely to maintain its quality and prevent bacterial growth. Here's how to thaw a colostrum syringe:

• Remove the syringe or collector from the freezer: Take the syringe out of the freezer and check the label to ensure you're using the oldest colostrum first.
• Place the syringe in the refrigerator: Put the frozen syringe in the refrigerator and allow it to thaw gradually. This process can take a few hours, depending on the volume of colostrum in the syringe. Avoid thawing colostrum at room temperature, as this can lead to bacterial growth.
• Use within 24 hours: Once the colostrum has thawed, use it within 24 hours. Do not refreeze thawed colostrum, as this can cause a loss of nutrients and increase the risk of bacterial contamination.
• Warm the colostrum: If your baby prefers warmed milk, you can gently warm the thawed colostrum by placing the syringe in a cup of warm water for a few minutes. Never use a microwave to warm colostrum, as this can create hot spots that could burn your baby's mouth and destroy the beneficial properties of the colostrum.
• Check the temperature: Before feeding your baby, always test the temperature of the colostrum by placing a small drop on the inside of your wrist. It should feel warm, not hot.
• Feed your baby: Once the colostrum is at a comfortable temperature, you can feed it to your baby using the syringe. Gently squeeze the syringe to release the colostrum into your baby's mouth, or use a clean finger to let your baby lick the colostrum off.

If you need to use the colostrum urgently and don't have time to thaw it in the refrigerator, you can use a bowl of warm water to thaw it more quickly. However, be sure to use the colostrum immediately after thawing and do not leave it at room temperature for an extended period.

How to Warm Up Colostrum

When it's time to feed your baby, you may choose to warm up the colostrum to make it more comfortable and appealing for your little one. Here's a safe and easy method to warm up colostrum:

• Prepare a warm water bath: Fill a bowl or a cup with warm water. The water should be warm to the touch but not hot. Avoid using boiling water, as this can destroy the beneficial properties of the colostrum and potentially cause burns.
• Place the colostrum container in the water: Put the syringe or container of colostrum in the warm water bath. If using a syringe, ensure that the cap is tightly sealed to prevent water from entering the syringe.
• Let it sit for a few minutes: Allow the colostrum to sit in the warm water for a few minutes until it reaches a comfortable temperature. The exact time will depend on the volume of colostrum and the initial temperature of the water.
• Gently swirl the container: Gently swirl the syringe or container to evenly distribute the heat and ensure there are no hot spots.
• Check the temperature: Before feeding your baby, always check the temperature of the colostrum by placing a small drop on the inside of your wrist. It should feel warm, not hot. If it feels too warm, let it cool down for a minute or two before checking again.
• Feed your baby: Once the colostrum is at a comfortable temperature, you can feed it to your baby using the syringe or by transferring it to a bottle.

If your baby is content with room-temperature colostrum, there is no need to warm it up. Some babies may even prefer colostrum slightly chilled from the refrigerator. Ultimately, the most important thing is to ensure that the colostrum is at a safe, comfortable temperature for your baby.

How to Feed Colostrum to Your Baby

Feeding colostrum to your newborn is an essential part of providing them with the best possible start in life. Here are some methods and tips for feeding colostrum to your baby:

Using a syringe:

• Gently draw up the colostrum into the syringe, ensuring there are no air bubbles.
• Position your baby in a semi-upright position, supporting their head and neck.
• Place the tip of the syringe into your baby's mouth, pointing towards their cheek to avoid triggering the gag reflex.
• Slowly and gently depress the plunger, allowing your baby to control the pace of the feeding. Be careful not to squeeze too quickly, as this may cause your baby to choke or sputter.

Finger feeding:

• Wash your hands thoroughly and ensure your fingernail is short and smooth.
• Place a small amount of colostrum on your clean finger.
• Gently touch your finger to your baby's lips, allowing them to lick and suck the colostrum off your finger.
• Repeat this process until your baby has consumed the desired amount of colostrum.

Cup feeding:

• Pour a small amount of colostrum into a clean, sterile cup.
• Support your baby in a semi-upright position and bring the cup to their lower lip.
• Tilt the cup slightly so that the colostrum reaches your baby's lips, and allow them to lap up the colostrum at their own pace.
• Continue this process until your baby has consumed the desired amount of colostrum.

Breastfeeding:

• If your baby is able to latch onto your breast, you can feed them colostrum directly through breastfeeding.
• Ensure your baby has a deep, comfortable latch and allow them to nurse on each breast for as long as they desire.
• If your baby has difficulty latching or you are not producing enough colostrum, you can use one of the above methods to supplement your breastfeeding.

You need to be patient and gentle when feeding colostrum to your baby. Some babies may take to it easily, while others may need more time and practice.

Can You Give Colostrum to Older Babies

While colostrum is typically associated with newborns, it can also be beneficial for older babies in certain situations. Here are some instances where giving colostrum to older babies may be appropriate:

• Boosting immunity: If your older baby is sick or has a weakened immune system, giving them colostrum can help provide an extra dose of antibodies and immunoprotective factors to help fight off infections and illnesses.
• Supplementing solid foods: As your baby starts eating solid foods, you can mix a small amount of colostrum into their food to provide additional nutrients and immune support.
• Premature babies: If your baby was born prematurely and you have excess colostrum stored, you can continue to give it to them even as they grow older to help support their growth and development.
• Adoption or surrogacy: If you have adopted a baby or used a surrogate, you may choose to give them donor colostrum to provide them with the benefits of this nutrient-rich substance.
• Relactation: If you have stopped breastfeeding but wish to start again, expressing colostrum can help stimulate milk production and provide your baby with the benefits of colostrum.

While colostrum can be beneficial for older babies in these situations, it should not be used as a substitute for regular breast milk or formula unless directed by a healthcare professional. Older babies have different nutritional needs than newborns, and colostrum alone may not provide all the necessary nutrients for their growth and development.

Is Frozen Colostrum Good for a Sick Baby

Yes, frozen colostrum can be beneficial for a sick baby. Colostrum, whether fresh or frozen, contains high concentrations of antibodies, white blood cells, and other immunoprotective factors that can help support your baby's immune system and fight off infections.

Here are some reasons why frozen colostrum can be good for a sick baby:

• Antibody protection: Colostrum contains high levels of antibodies, particularly immunoglobulin A (IgA), which can help protect your baby's mucous membranes from infections and illnesses. These antibodies can be especially beneficial when your baby is sick and their immune system is compromised.
• Immune system support: In addition to antibodies, colostrum contains white blood cells and other immune-boosting components that can help stimulate your baby's immune system and help them recover from illness more quickly.
• Easy to store and use: Frozen colostrum can be stored for several months, making it readily available when your baby needs it most. You can thaw and use frozen colostrum as needed to help support your baby's health and recovery.
• Gentle on the digestive system: Colostrum is easy for babies to digest, even when they are sick and their digestive system may be sensitive. The small volume and concentrated nature of colostrum can be easier for a sick baby to tolerate than larger amounts of regular breastmilk or formula.

If you have frozen colostrum and your baby becomes ill, you can thaw and feed it to them using a syringe, cup, or other feeding method recommended by your healthcare provider. It's essential to follow proper colostrum storage and thawing guidelines to ensure the safety and quality of the colostrum.

What to Do With Leftover Colostrum

If you find yourself with leftover colostrum after your baby's birth, there are several ways you can put it to good use:

• Continue feeding it to your baby: You can continue feeding your baby any leftover colostrum even after your mature milk has come in. You may mix this with your mature milk or on its own; colostrum continues to give your baby valuable nutrients and immune protection.
• Donate it to a milk bank: You can donate colostrum that you are in plenty of and meet the required health terms. The donated colostrum is especially good for babies born prematurely or with various sicknesses that prevent them from taking their mother's colostrum.
• Use it for skin care: The very special properties of this 'first milk' are valuable not only internally but also for your baby's skin. Smear a little colostrum on your baby's diaper rash, minor cuts, or scratches for soothing and healing of the skin. Colostrum can be applied to sore or cracked nipples of breastfeeding mothers to aid in healing.
• Freeze it for later use: You are able to freeze it for a later date if you have no immediate need for your left-over colostrum. Frozen colostrum may be stored for up to 6 months in a deep freezer and then thawed out for use in caring for your baby or skin.
• Discard it safely: When you have colostrum left over that you cannot use or donate, then it is time to take steps to safely discard it. You can safely pour the colostrum down the drain or into the toilet. Clean the containers with soap and water, then throw those away in the trash.

Can I Pump Colostrum After Birth

Yes, you can pump colostrum after giving birth. In fact, pumping can be an effective way to stimulate milk production, collect colostrum for storage, and provide your baby with the benefits of colostrum even if they are unable to nurse directly at the breast.

Here are some reasons why one might prefer to pump colostrum after birth:

• Stimulating milk production: Pumping colostrum acts as a stimulant for the breast tissues, inducing more production of milk as your baby may not be in a position or willing to nurse very frequently.
• Collecting colostrum for storage: In case you are producing more colostrum than your baby may require, pumping is one method of collection and storage for future use.
• Feeding a premature or sick baby: If your baby is born prematurely or is too sick to nurse directly at the breast, pumping colostrum allows you to provide them with the vital nutrients and immune support they need.
• Relieving engorgement: Just after birth, colostrum swells in your breasts within the first few days. You are able to relieve this discomfort with pumping because it reduces the risk of complications from blocked ducts or mastitis.

Most people suggest that hand expression or a combination of hand massage and an electric breast pump, like the Momcozy M9, is effective for colostrum extraction since it's thicker than regular breast milk and can be more challenging to express. The Momcozy M9 is specifically designed for post-birth colostrum pumping, mimicking a baby's natural sucking rhythm to enhance comfort and efficiency. It boasts adjustable suction levels in a closed system that prevents backflow, ensuring a hygienic experience. Additionally, it comes with various flange sizes to accommodate different nipple shapes and sizes.

FAQs About Storing Colostrum

Q1: How long can colostrum be stored in the fridge?

Colostrum can be safely stored in the refrigerator at a temperature below 40°F (4°C) for up to 4 days. Colostrum should be kept, if possible, at the back of the refrigerator, as the temperature there is highly stable, rather than in the door compartments where there is greater fluctuation in temperature.

Q2: How long can colostrum stay out at room temperature?

Freshly expressed colostrum can be left out at room temperature (no higher than 77°F or 25°C) for a maximum period of 4 hours. In case the room is very hot or humid, it will be better to use the colostrum as soon as possible or immediately refrigerate it to avoid chances of bacterial development.

Q3: How long does colostrum last in the freezer?

Colostrum can be frozen at 0°F (-18°C) or colder for up to 6 months. Frozen colostrum, however, is best used within 3-4 months for optimum quality. Containers of colostrum should be stored in the back of the freezer, as the temperature is most consistent there, and colostrum should not be stored in door compartments.

Q4: Can I store colostrum in a bottle?

Yes, colostrum can be stored in a clean and sterilized bottle. Glass bottles are comparatively good because they are easy to clean and sterilize and also do not contain harmful chemicals. Avail the services of a bottle that has a tight-fitting lid just to avoid leakage or bacterial contamination. When you store colostrum in a bottle, the date and time of expression should be labeled on the bottle, and use the oldest colostrum first.

Q5: Can I store colostrum in breast milk storage bags?

Yes, you can store colostrum in a breast milk storage bag. These breast milk storage bags are specifically designed for storing human milk and are pre-sterilized, leak-proof, and freezer-safe. They also have a space for labeling, with the date and time of expression. If using storage bags, first express into a clean container and then pour it into the bag. Freeze them flat to make thawing easy and allow more room in the freezer.
