First-time mom or not, there might be a million questions going in your head regarding breastfeeding your little munchkin. There are times when you run out of milk, and then there are times when you don’t produce enough, also, at times the baby is not hungry. At times, the mom needs to go away for a while, so what do you do?



What you need the most to solve this problem is breast milk storage bags. These are used for storage, freezing milk, and the best for traveling moms. And while bottles are also an option, there are reasons that the milk bags have managed to stay in demand for recent mothers. That’s precisely what we are going to discuss in this vital piece of article. Let us guide you through it.


Advantages Of Using Breast Milk Storage Bags

Breast milk storage bags bring along the following benefits. We also compared the milk bags with bottles, so that you get a clear picture. 


Easy Storage

Breast milk storage bags can be conveniently stored. Most of the milk storage bags come with a gusseted bottom, which makes them self standing. At the same time, they can also be stored flat, ideal for flat freezing. When frozen flat, it also allows for faster thawing of your precious breast milk.



Many milk storage bags have convenient mouths, which make them easy to use. Hence, reducing the amount of spillage of milk, as there’s no need to transfer. They are also ready to pump milk into, though you may need additional attachments for this.


Leakproof & Travel Friendly

Though different variants of milk bags come with different mouths, the most common ones are double zippered. These double zippers ensure that the milk bag doesn’t open when traveling, and the milk doesn’t spill. Some bags also have threader caps, adding to the convenience. 


Easy To Label

One significant advantage of milk storage bags over bottles is that they are easy to label. You will no longer have to bother about which pack was filled earlier and which later. Besides, you do not want to feed incredibly stale breast milk, so with the label, you can keep all the kids in check. Tags can also come in handy to write names of toddlers if you are blessed with more than one.

Pre-Sterilized & One-Time Use

Unlike bottles, milk bags often come pre-sterilized, making them ready to use as soon as they are out of the packet. Additionally, you won’t have to bother about sterilizing them again since they are disposable, and all you have to do is to pick another bag.



How To Use Breast Milk Storage Bags?

Most breast milk storage bags come with a user manual to guide moms, along with information on freezing, storage, etc. And while these details are specific for different products, here are a few steps on the necessary procedure to use milk bags.

  1. Ensure that your nipples and hands are clean. Use a soft cotton pad, slightly moistened to clean the nipples. 
  2. Prepare your pumping device if you are not going to express milk manually. Also, prepare the milk bag or container.
  3. Unfasten the milk bag. If possible, pump the milk directly into the bag, while making sure not to touch the inside since it is sterile.
  4. Fill the milk, but not above the maximum mark on the bag.
  5. Release air (if any) and fasten the bag as soon as possible. 
  6. Do not forget to mention the date and time, so that you know the life of the breast milk.
  7. Discard bag after use. 


Efficient Ways To Maximize Breast Milk Storage Bags

Here are a few tips on maximizing the benefits of breast milk storage bags. Please note that the following information is as per CDC guidelines for the storage and preparation of breast milk.


When Storing Fresh Breast Milk

  • You may store freshly expressed or pumped milk for up to 4 hours at room temperature.
  • But in the refrigerator, you may store the milk for up to 4 days when stored in a sterile milk bag.
  • In the freezer, you may store it even up to six months at a time. A few more months (not more than twelve) are also acceptable. 


For Milk Once Thawed

  • Breast milk once thawed, shall NEVER be frozen again.
  • However, it will last for a couple of hours at room temperature.
  • While you may store in the fridge for not more than 24 hours.


Leftover Milk

  • The milk left over after feeding the baby will stay fit for next feeding only within two hours of the last feeding. 


Additional Tips

  • Do not forget to label the storage bag when filled. Mention both the date and time. 
  • When filling the milk storage bag, fill only up to the maximum mark. Or at least leave an inch of gap from top, since milk expands on freezing.
  • Store milk on the inner side, and never on in the door compartments of the refrigerator or freezer.
  • Leave the milk bag at room temperature for thawing. Do not heat the milk at any cost, since it kills all the nutrients.
  • Never reuse the breast milk storage bags.
