Breast milk storage and thawing can be a convenient way to feed your baby, but it’s important to do it right to maintain its nutritional value. Let’s explore the best practices for thawing breast milk while preserving its benefits for your little one.

1 Proper Breast Milk Storage

After pumping, breast milk should be stored in glass or plastic bottles, or specialized milk storage bags. It’s important to leave some empty space in the container, as milk expands when frozen.

To avoid waste and maintain hygiene, fill the bags/bottles with only the amount of milk your baby typically consumes in one feeding. Thawing and refreezing milk is not recommended to preserve its nutritional content.

Proper Breast Milk Storage

Breast milk can be stored at room temperature (19-22°C) for up to 4 hours, in the refrigerator (4-6°C) for 48 hours, in the freezer for 1 month, and in a deep freezer (-18 to -20°C) for up to 6 months.

The longer breast milk is stored, the more its taste and nutritional profile may change, so it’s best to use it sooner rather than later. Labeling containers with the date and time of expression can help you keep track of its freshness.

2 How to Properly Thaw Breast Milk

For Milk Stored in the Freezer

To thaw frozen milk, transfer it to the refrigerator a day before you plan to use it. If you’re in a hurry, you can also submerge the container in a bowl of cool water to speed up the process.

Once the milk is completely thawed, gently swirl or invert the container to mix the fatty portion with the watery portion. Then, use warm water to further heat the milk to a comfortable temperature for your baby.

Thawing in the refrigerator may result in a thin layer of fatty cream on top of the milk. This is normal and can be easily mixed back into the milk by gently swirling or inverting the container.

For Milk Stored in the Refrigerator

For milk stored in the refrigerator, simply remove it and submerge the container in warm water (around 40°C) until it reaches a comfortable temperature for your baby to drink. Avoid using hot water, as this can break down important nutrients and antibodies in breast milk.

3 Important Considerations for Thawing Breast Milk

Here are some key points to keep in mind when thawing breast milk:

Avoid thawing breast milk at room temperature, as this can provide an opportunity for bacterial growth. Always thaw in the refrigerator or using the cool water method mentioned above.
Do not use a microwave or high heat to thaw or warm breast milk. The high temperatures and electromagnetic waves can destroy vitamins and other essential nutrients, and it’s also easy to accidentally overheat the milk, which could burn your baby’s mouth.

Important Considerations

Avoid shaking the container during or after thawing, and avoid sudden temperature changes. This can affect the structure of the antibodies and other components in breast milk, reducing its nutritional value.
Storage after thawing: Once thawed, breast milk can be stored at room temperature for up to 4 hours or in the refrigerator for up to 24 hours. Previously frozen and warmed milk should be used within 2 hours of warming, and any leftover milk should be discarded after 24 hours in the refrigerator. Do not mix fresh milk with previously frozen milk.
Changes in taste: Thawed milk may develop a slightly sour taste and smell due to the enzyme lipase. Most babies will drink it without issue, but if your baby is sensitive to the change, you can gently heat the milk on low heat until you see small bubbles forming, then let it cool before feeding.

We hope you find these tips on thawing breast milk helpful. Remember, proper thawing ensures your baby receives the full nutritional benefits of your breast milk.

Frequently asked questions

Proper defrosting and preservation of milk is crucial for maintaining the nutritional value and safety of the milk for infants and young children. It ensures that harmful bacteria are eliminated, reducing the risk of foodborne illnesses. Additionally, proper handling practices help retain the essential nutrients in the milk, contributing to the overall health and well-being of young ones.

The recommended method for safely defrosting frozen milk is to use the refrigerator. Place the frozen milk in the fridge, ideally in a container to prevent leakage, and let it thaw slowly. This gradual process may take 12-24 hours, but it ensures the milk thaws evenly and safely. Avoid using a microwave or warm water, as they can create hot spots and affect the milk’s nutritional value.

It is not recommended to refreeze thawed milk. Refreezing can compromise the quality and safety of the milk. However, if the milk has been thawed slowly and safely in the refrigerator and has not exceeded the safe storage time, it can be refrozen once, although there may be some loss of quality.

Once milk has been thawed, it should be treated like fresh milk. Use it within 24-48 hours after thawing and always check the smell and taste before feeding it to your little one. Store it in a sealed container at the back of the fridge, where the temperature is more consistent.

Thawed milk can go bad, and it’s important to watch for signs of spoilage. Look for changes in smell, taste, or appearance. If the milk develops a sour smell or taste, or if you notice any mold growth, discard it immediately. Also, check for lumps or curdling, which indicates that the milk has spoiled.

To preserve the nutritional value, always defrost milk slowly in the refrigerator. Avoid exposing it to extreme temperatures or direct sunlight. Use an airtight container to prevent the milk from absorbing odors or flavors from other foods. Additionally, practice proper hygiene when handling milk, and ensure your storage containers are clean and sanitized.

When storing thawed milk in baby bottles, always use clean and sterilized bottles and teats. Store the bottles in the refrigerator, and clearly label them with the date and time of preparation. Discard any unused milk after 24 hours, or sooner if your baby doesn’t finish the bottle within 1-2 hours of starting the feed.

If you’re in a hurry, you can safely speed up the defrosting process by placing the frozen milk in a watertight bag and submerging it in cold water. Change the water every 30 minutes until the milk is thawed. Alternatively, hold the container of frozen milk under cool running water. These methods are safer alternatives to using a microwave or warm water.

Always dispose of unused or expired thawed milk safely. Do not pour it down the sink, as it can cause clogging and attract pests. Instead, pour it down the drain while running hot water, or dilute it with water and dispose of it in a sealed container in the trash. Wash and sanitize any containers or bottles that held the expired milk.

Always follow safe milk storage and handling practices. Purchase milk with a later expiration date and transport it home promptly, storing it in the refrigerator or freezer as soon as possible. Use clean and sanitized containers, and label them with the date. Practice good hygiene, washing your hands before handling milk, and keep your refrigerator and freezer clean and at the correct temperatures.
