Best Mini Fridge for Breast Milk

There’s nothing more nutritional and beneficial for a baby than a mother’s natural milk. However, when the mother is busy it can be hard to find a solution that lets a woman store breast milk.

Transporting breast milk to ensure your child always gets fresh breast milk can be a challenge, too. While cooler bags for breast milk, they aren’t able to bring the temperature of the breast milk down to ensure it stays fresh for a long time.

On the other hand, storing breast milk in a shared fridge could contaminate the milk or upset your coworkers.

This is where a portable mini fridge for breast milk comes into the picture. They’re portable, efficient, and small. With mini-fridges, you can get access to refrigerated breast milk and store it in your car, or your office while you’re traveling.

This ensures that breast milk is always available and fresh for your little one whenever you need it.

That said, mini-fridges also get a bad reputation for storing a mother’s milk. We don’t see any reason why a working mother can’t use one to transport milk from her home to another to ensure their baby gets fresh breast milk.

Moreover, if you often make the mistake of expressing more breast milk than the amount your baby needs then a portable mini fridge will do a good job of freezing milk bottles.

If you’re trying to ensure breast milk stays fresh for a longer period of time, read on to find the best mini fridge for breast milk.

How to Find a Portable Mini Fridge to Store Breast Milk

Breast milk storage can be a complicated task since there are several considerations that you’ll have to make. Many features combine to form the perfect mini-fridge. With the right product, you can keep breast milk fresh for a long time. Listed below are some features that matter.

Temperature Control

A mini-fridge’s ability to adjust the temperature of breast milk is a useful feature that lets you control how cold the milk gets. To ensure it stays safe for consumption, you’ll have to sustain the temperature of your fridge at 39 degrees Fahrenheit or 4 degrees Celsius.

That is why it’s essential that you buy a fridge that can maintain this temperature across all compartments.

Moreover, your ability to store breast milk can also be useful if you’re planning on donating it to someone who needs it.

This is also where frozen breast milk can be useful. That said, this factor also depends on how long you plan to put milk in the freezer or fridge.

Defrosting the milk often can lead to bacteria growth which can give your baby a stomach infection fairly easily. We would recommend getting a mini-fridge that gets the job done in the shortest amount of time.

Also, try not to move the fridge around too much if it isn’t built for that purpose. Changing the surroundings of the refrigerator can mess with the cooling process, too.

The Capacity and the Size

To ensure you can store breast milk easily, you’re going to need a storage capacity of at least 4 liters. This is enough to store four or five 17-ounce bottles of breast milk. Another essential factor you should consider is whether you plan to keep your pump parts in your mini-fridge.

If you plan to store them, you won’t have to sterilize them after every use.

That said, these parts will take up additional space in your fridge so you will have to take this into consideration.

Generally, the best options to keep breast milk cold are either tall or cube-shaped. Not only do they keep breast milk cool, but they’re also compact which means they can easily fit beneath a desk or on top of a desk.

A cube-shaped model specifically is also a lot more portable. It makes it easy to transport breast milk. Although they have lesser racks and a smaller capacity, they can provide ample space if you’re just looking for a short-term option for breast milk storage.

A taller mini fridge for breast milk has more room but it can take up more space. If you intend to express milk while you’re at work and if you have ample space at work, then you should consider buying a bigger model.

However, if you’re traveling and don’t have a lot of storage space, you should prefer buying a more compact mini-fridge. It’s going to take up less space and you can also power it through your car’s cigarette adapter.

You can also match this mini fridge with a stellar cooler pouch to transport breast milk from your home to work or while you’re hanging out with friends.

If the mini-fridge has a small size, you can take it with you on your expeditions around the world. However, if it has a sturdy build, the portability factor isn’t going to be useful since the fridge is going to be too heavy to carry around.

With a portable mini-fridge, you can easily carry it around and move breast milk from one spot to another. Whether you’re indoor or outdoor, the cooling capacity isn’t going to get affected. This is also another great reason to take the structure of the mini into account.

Consider looking for mini-fridges that have a light construction and a robust carrying handle if you plan to move it regularly.

Moreover, some mini-fridges can also run on your car’s cigarette adapter. This means that if you’re moving the mini-fridge in your car, you’ll be able to keep the milk bottles stored at the ideal temperature.

Storage Time

If you’re planning to access stored breast milk often, you’ll have to make several essential considerations. How often do you have to use it? How long does it take you to restore the same quantity?

If you’re planning to store breast milk for up to 9 days, you might prefer a long-term storage option like the Astroai mini-fridge.

On the other hand, if you’re a mom who wants to give her child breast milk as nutritious as possible, you may prefer the short-term options in the market today.

These have thermoelectric semiconductors that are the best mini fridges for traveling.

You can store milk in them easily for 24 hours before you transfer it into a freezer.

Energy Efficiency

If you’re looking for an efficient and portable mini fridge while you’re on the go, you’ll have to be aware of its energy usage levels. If you plan to keep one in your car, you’ll have to opt for a mini milk fridge that has reduced energy consumption and offers several supporting options for power.

These cigarette adapters, or a USB port.

Refrigerating vs. Freezing Breast Milk: The Differences

There are some key differences between the two processes. While you can keep freshly expressed milk at room temperature for four hours, you should consider using a cooler.

This will help you keep it fresh for at least a day. You could be at work during this time or your child could be at daycare.

Moreover, you can also keep breast milk in a fridge for up to five days, while frozen milk can be kept in a freezer for up to 12 months!

However, you must remember that keeping breast milk frozen for extended periods of time can result in high losses of vitamin C, which is a vital nutrient for strengthening the bones of your baby. It’s vital that you feed newborn babies milk that is high in vitamin C.

While a fridge should be at 4 degrees celsius, a freezer should usually be below – 18 degrees celsius. This way, you can rest assured knowing your breast milk is preserved.

The Duration and the Technicalities Involved

Time and time again, medical research has proven that breast milk is the most vital nutrient resource for newborn babies. No other food comes close in terms of nutrition.

After six months, experts advise that the baby is fed some solid food along with breast milk. For a working mother, however, this can be a challenge.

While mini-fridges for breast milk can ensure that your milk stays cold, your child’s nutritional needs change with time and this is an essential factor you should consider. By all means, you should prioritize feeding them fresh breast milk.

Storing Breast Milk: Four Different Ways

There are four prominent ways of storing breast milk. The first is the easiest and the cheapest way to do it. You can simply leave it outside in a bottle or in any other form of packaging. This way, you’ll have to make sure that you use it within four hours.

Using it after four hours can create several problems for your baby.

The second option you can go for is using a cool box. This will help keep milk fresh for up 48 hours. However, you can extend this period if you simply keep restocking the ice cubes to keep the milk cool.

This way, you can achieve the same duration you would with a fridge. This is also an energy-efficient method of storing breast milk since you’re not going to be using a power appliance or any electricity.

Instead, you’re going to be using leftover ice cubes from your fridge. This method is also lighter than most small fridges since you’re not going to use any electrical components (made out of heavy metal) to keep the milk cool.

The third way of keeping breast milk cooled is by using a fridge. You’ll have to set the fridge at a temperature of less than four degrees to ensure it can preserve the nutrients in the milk. This way, it’ll last five to eight days without causing any problems.

The fourth and last option for storing breast milk is by keeping it in a freezer. The milk’s life for this option can vary since it depends on how long you intend to keep the milk in the freezer and the temperature of the appliance.

You’ll also have to consider the fact that there are other items in the freezer. You’ll either have to move them or put the milk in a different freezer.

Another crucial factor to consider is how often you intend to take the milk out of the fridge. That’s because if you continuously take an item out of the freezer, defrost it, and then freeze it again, you’re going to reduce its usable life greatly.

According to healthcare professionals, you should only defrost a food item once. When you defrost it often you increase the chances of bacteria infecting the food.

This can cause health-related complications that can affect children easily since they have weaker immune systems.

If you’re trying to be extra efficient with your milk, we recommend storing it in small quantities in the same compartment so that you only have to defrost one serving.

While you’re at it, try assembling a storage compartment that is made of washable equipment so that you can save yourself time in the long run.

Tips for Storing Breast Milk in Mini Fridges

  • You should never use hot water or a microwave to thaw the milk you’ve frozen
  • Always use a sterilized container to store breast milk in your mini-fridge. You’re also going to find plastic milk bags on several e-commerce websites. It’s relatively easy to find BPA-free or hard plastic bottles to store breast milk, too. We don’t recommend using breast milk in a glass bottle since it can break rather easily
  • If you’re storing milk in a freezer, you’ll have to thaw it before you can use it. To do this, you can place the milk in a freezer the day before you intend to use it. You must use this milk 24 hours after thawing it
  • Label every bottle that you’re putting into your fridge with the date. Try to use the older bottles first
  • All in all, ensure that everything is as clean as it possibly can be while you’re handling breast milk since small impurities can encourage bacterial growth far too easily
