What Is Pumping Fridge Hack?

So, what exactly is the fridge hack pumping? Well, it's a simple yet genius storage method for your pumping equipment. Instead of going through the hassle of washing and sterilizing all your pump parts after each session, you give them a quick rinse and pop them straight into the fridge. Yep, that's right – no need for the whole cleaning shebang every single time! You can store them in a zip-top bag or any airtight container you have on hand.

The magic behind this fridge hack lies in the cold temperature of the fridge, which helps prevent bacterial growth. This means you can reuse your pump parts for multiple sessions throughout the day without worrying about contamination. It's a real lifesaver for busy moms, especially when you're on a quick break at work or out and about with your little one.

But let's be real here – is it actually safe? Many moms swear by this technique, but safety is always a top priority when it comes to feeding our babies. So, let's dive into the details and discuss the pros, cons, and safety precautions of the pumping fridge hack.

Pros and Cons of Pumping Fridge Hack

The pumping fridge hack, while innovative and convenient, comes with its own set of advantages and disadvantages. Understanding these can help you decide whether this method is suitable for you.



  • Time-Saving: Perhaps the most significant benefit of this hack is the time it saves. You can avoid the time-consuming process of washing and drying pump parts after each use, which can be particularly advantageous during a hectic day or night.
  • Convenience: This method simplifies the logistics of pumping, especially for mothers who return to work or are frequently on the go.
  • Reduced Wear and Tear: By washing the pump parts less frequently, you can potentially extend the lifespan of these accessories, as constant cleaning can degrade the materials over time.



  • Risk of Contamination:If not managed properly, there is a potential risk for bacterial growth. Even though refrigeration slows down bacterial proliferation, it doesn't eliminate it completely. This makes meticulous attention to refrigeration times and hygiene practices essential.
  • Dependence on Refrigeration:This hack requires consistent access to a clean and properly functioning refrigerator, which might not always be available, especially when traveling.
  • Not Suitable for All Situations: The method is not suitable for all mothers and babies.If your baby is under 2 months old or having compromised immune systems, the CDC advises against using the pumping fridge hack and recommends washing the parts after each use.

How to Safely Use Pumping Fridge Hack

Despite the concerns, many moms find the fridge hack to be a valuable time-saving technique. If you're considering using this hack, it's important to follow best practices that mitigate risks, especially concerning milk contamination. Here's how to use this method effectively and safely:

  1. Clean Initially: Before the first use of the day, ensure all pump parts are thoroughly cleaned and sterilized. Start each day with a fresh, clean setup to minimize any risk of bacterial contamination.
  2. Rinse Before Refrigerating: After each pumping session, rinse your pump parts with cool water to remove any milk residue. If a sink is unavailable, you can also wipe them with a clean paper towel.
  3. Store Properly: Place your rinsed pump parts in a clean, airtight container or zip-top bag. Make sure to seal the container tightly to limit exposure to the air and potential contaminants in the fridge.
  4. Label and Date: It's a good idea to label and date your container or bag with the time and date of pumping. This helps you keep track of how long the parts have been stored and ensures you use them within a safe timeframe.
  5. Limit Storage Time: While the fridge hack can be a time-saver, it's important not to store your pump parts in the fridge for too long. The CDC recommends using them within 24 hours to minimize the risk of bacterial growth.
  6. Follow Up with Regular Cleaning: Even though you're using the fridge hack, it's still essential to thoroughly clean your pump parts at least once a day. Use hot, soapy water and a bottle brush to clean all parts thoroughly, then rinse and air dry.
  7. Consult with a Professional: If you have any concerns about the safety of the fridge hack or your pumping routine, don't hesitate to consult with a lactation consultant or healthcare professional. They can provide personalized advice based on your situation.

Other Practical Tips to Make Pumping Easier

In addition to using the pumping fridge hack, there are several other strategies that can make the pumping process more manageable and efficient for you. Here are some practical tips to enhance your pumping experience:

  • Establish a Routine: Consistency can help increase milk supply and reduce stress. Try to pump at the same times each day to maintain a steady flow and make the process a natural part of your daily schedule.
  • Create a Comfortable Pumping Space: Make sure your pumping area is comfortable, private, and equipped with all the necessary supplies. This could include a supportive chair, a small table for the pump, and easy access to water and snacks.
  • Stay Hydrated and Nourished: Keeping well-hydrated and eating balanced meals can help maintain your milk supply. Always have a water bottle and healthy snacks nearby during pumping sessions.
  • Use Hands-Free Pumping: Invest in hands-free pumping options like a comfortable hands-free pumping bra or a wearable breast pump. This allows you to multitask effortlessly during your pumping sessions.

The eufy wearable breast pump, for example, is equipped with a built-in heating element and a precision temperature sensor to offer seven adjustable heat settings. This feature closely mimics the natural warmth of a baby's mouth, enhancing your milk flow and making pumping sessions more comfortable, especially after using the fridge hack where pump parts can be cold to put on in subsequent sessions.

  • Practice Relaxation Techniques: Stress can impact milk supply, so practicing relaxation techniques before or during pumping can be beneficial. Listening to calming music, reading, or meditating can help create a more serene environment.


As we've learned, the fridge hack pumping can be a valuable time-saving technique for breastfeeding moms. However, it's crucial to approach it with an understanding of the potential downsides and safety measures. By adhering to the proper cleaning and storage guidelines, you can safely incorporate this method into your pumping routine. The additional tips we shared can also enhance the efficiency and comfort of your pumping sessions, making the overall experience more positive and successful. Remember, the best approach is the one that fits seamlessly into your lifestyle and meets your baby's health needs.


Can I pump into the same bottle all day?

Yes, you can pump into the same bottle throughout the day, but it's important to follow safe storage practices. After pumping, refrigerate the milk within four hours. When adding fresh milk to already cooled milk, make sure the fresh milk is also cooled before combining. This prevents the warm milk from raising the temperature of the cooled milk, which can promote bacterial growth.

Can the fridge hack be used for premature or health-sensitive babies?

The fridge hack is generally not recommended for premature or health-sensitive babies. These babies are more susceptible to infections, so it's essential to follow strict hygiene practices, including washing pump parts after each use. Consult with a healthcare professional for specific guidance on pumping and storing breast milk for premature or health-sensitive babies.
