How to defrost breast milk in bottle warmer?

It is common for all new or fresh mothers to freeze their breast milk as a stock for later use. Now the question is, how to defrost or thaw frozen breast milk? What are the right ways to thaw frozen breast milk? Because you don’t want to give your baby iced milk as his meal. Let’s find out the convenient defrosting breast milk methods in this guide. 

5 effective Ways of thawing breast milk in bottle warmer

You can thaw or defrost your frozen breast milk in multiple ways that are convenient and effective. You can carefully follow any thawing methods below to convert frozen breast milk into a liquid state. Read all the methods mentioned below attentively and choose which will go best with your situation.

1. The fridge method

The refrigerator defrosting method is one of the simplest and easiest methods to thaw breast milk. You do not have to put any effort into thawing the milk. Instead, you only need to put the bottle or bag of frozen breast milk in the fridge. But, this will take a long time to defrost. So, you need proper planning before thawing the frozen breast milk, which can take up to 12 hours.

For example, if you know that your baby will need breast milk in the morning and you have frozen stock, put that stock inside the fridge the night before. In this way, the milk will slowly be defrosted. This method will work only if you have plenty of time. Make sure your baby finishes that milk within 24 hours after completely defrosting. 

2. With the bowl of warm water

This is a two-way method, usually picked by mothers to save themselves from the struggle of warming breast milk. Take out a bowl and add some hot water to it. You can put the bag or bottle of frozen breast milk inside this bowl. 

Make sure that the bowl is large enough to dip the bottle or the bag entirely in it. This way, you can not only thaw frozen breast milk but can also warm it at the same time. If you want a quick warming process, use breast milk storage bags in this method. Keep replacing the current water with hot water, if you want quicker results as the current water will get cold due to the frozen breast milk. 

3. With a specific bottle warmer

The bottle warmers are yet again in the game to save you from the struggles of defrosting breast milk and warming them up. Now you will ask, how to defrost frozen breast milk in the bottle warmer? 

Although bottle warmers can defrost breast milk and warm it in a safe and slow-heated method, so that no milk properties are destroyed. We suggest you defrost the breast milk in the ways mentioned earlier as defrosting the milk in the bottle warmers can lead to defrosting in patches that can cause uneven temperature in the milk. So, use the methods above to defrost and then warm the milk in the bottle warmer using safe warming temperatures. Bottle warmers will also help you to heat the breast milk on the go

4. Under the running water

If you need the fastest method to thaw and warm your frozen breast milk, then you should pick the warm running water method. This method works more efficiently if you put the milk in the breast milk storage bag. The frozen milk will start to defrost shortly, and this is when you need to start massaging the breast milk storage bag with your fingers to break and melt the ice chunks. This will thaw the milk more quickly. You can use the cold running water and slowly switch to the warm water to heat up the milk. Remember, the water should only be warm, not burning hot. 

5. Dip in a cold water bowl

Parents or mothers only sometimes choose this method, but this could be a compelling idea. Dip the bottle or the bag of milk in the bowl of cold water, use the defrosted breast milk, and keep the rest inside the fridge. You can use the cold water bowl method if you need the milk in less than 12 hours. 

🍼 How can you handle warmed breast milk safely?

No matter how old your kids may get, you will always be concerned for their wellness, but when it comes to infants, they need more attention and care than anyone else in the house. Provide your little monster breast milk that is ultimately saved from bacterial growth, deterioration, and unhealthy enzymes. Follow the tips for this purpose:

➡️ Do not put the warm breast milk anywhere after defrosting; give it straight to your baby. If your baby does not want to drink, store that back in the refrigerator.

➡️ Never leave the defrosted and warm breast milk at room temperature.

➡️ Do not keep the leftovers of breast milk if your baby is full. Throw the milk right away.

➡️ Never refreeze the breast milk after defrosting it.

Methods to avoid defrosting frozen breast milk

No matter how busy a parent you might be, you will never want something for your kid that is not safe. Do not opt out of the fastest or easiest methods of thawing frozen breast milk. The procedures mentioned below fall in the “unsafe” category of thawing frozen breast milk you should avoid. 

1. Do not thaw in a microwave

A microwave is never safe for heating your frozen or defrosted breast milk. The microwave heating will create abnormal hot spots in the breast milk that can put your baby at risk of burning their mouth. 

Not only this, but microwave heating will also destroy the essential nutrients inside breast milk. Using a microwave for warming or thawing frozen breast milk is a big ‘No”. 

2. Do not thaw in boiling water

The boiling water will have a similar impact on the breast milk as the microwave heating. The hot spots will form in patches in the breast milk, and it will lose its potency, beneficial antibodies, and essential nutrients. 

3. Do not thaw at room temperature

Breast milk is an extraordinary living fluid enriched with multiple nutrients; it should not be thawed at room temperature. Suppose you defrost your frozen breast milk at room temperature. 

In that case, it will not only distort the vital nutrients, antibodies, and calcium but also provide the environment for unhealthy bacteria to grow and nourish. Breast milk must never be left on your room shelf, table, or elsewhere to thaw.

How long can you keep your breast milk frozen?

The freezing duration of breast milk depends on the temperature of your freezer.

If you have stored the breast milk in the standard fridge that has its door, then the milk can stay there for nine months.

It would be good to use the frozen breast milk within 6 months, but it would be far better if you use it in four months. Remember to put the date on the milk storage bags so you can remember the expiry. Always use the portion that you have frozen first.

If you have put the breast milk inside a chest freezer or a deep freezer, it can be stored for 12 months.

The milk will be safe in the frozen form, but its quality will start to change with time.

Vitamin C inside the breast milk would probably decrease after five months of being frozen.

Similarly, the colostrum will only stay in the milk for six months.

Why does your breast milk taste, look, or smell odd sometimes?

It could reflect your diet if you notice some usual changes in your breast milk, such as different odor, changed color, or weird taste. Sometimes, it could be a result of your baby’s life and growth. As your baby grows older, your milk will change its composition. 

If you see the defrosted breast milk in an unusual form, it could be due to the breakdown of the fatty acids. This form of milk is completely safe for your baby to feed.

If you are a States citizen, know that you can travel with proper breast milk storage per the rules of TSA (Transportation Security Administration). Declare your breast milk at the security check and show the breast pump as a medical device. 

The security agents will not test your milk if it is completely frozen. If it is semi-melted or defrosted, the security agents might inspect the milk bottles for explosives. 

You can ask the agents to wear gloves before checking the milk to save it from contamination. 

Ask for freezer

Make sure you are staying in a hotel room with a freezer. Remember to ask for such a room at the hotel reception. If there is no such room available, try to ask for space for your milk in the hotel freezer. 

Keep dry ice

Keep ice cubes or dry ice during your journey so the milk will stay as cold as possible. If you cannot do that, keep a cooler and refill it with fresh ice every time you stop at any station, rest house, airport, or eatery. 

Learn international travel rules

If you are traveling internationally, keep in mind that some additional rules are involved. Remember to read the rules and your traveling rights before you get on board.
