Benefits of using breast milk storage bags
In order to ensure the best health for babies, mothers have to spend 8-10 out of 24 hours of nursing or pumping for them. However, for such busy moms, it is too difficult to arrange enough time for their babies.
Now, you can store your own breast milk in a fridge for another use by pumping your milk into some storage bags and keep them frozen. Make sure you do the proper storage.
According to scientific research, breast milk could be kept for 6-8 hours at room temperature but more ideal to keep them in a refrigerator, and its expiry date will be lengthened to 5 days. Under freezing temperature, it is even stored for a year.
Of course, the quality of stored breast milk is not as good as a fresh one but it is much better than available industrial powder milk. Furthermore, it is more economical and safer when using storage bags to keep milk.
Compared with using glass containers or plastic bottles, breast milk storage bags are much cheaper and more convenient. Firstly, you don’t need to clean it due to its dispensability. Secondly, it only takes a small room in your fridge. Last but not least, pumping milk into storage bags is much faster and sometimes, your breast milk is too little to fulfill the plastic/glass containers.
The breast milk storage bags are made to be able to withstand the thawing or freezing as well as are firmly sealed in order to avoid leaking, therefore, you don’t need to worry when storing them in a refrigerator.
Drawbacks of using breast milk storage bags.
Breast milk storage bags are not totally perfect. In fact, they still have some unavoidable disadvantages.
As you know, the milk that is stored in a breast milk storage bag cannot be reused. It is only allowed to use one time, you have to throw it away after using. Consequently, it is not so eco-friendly in comparison with other options.
Although the storage bags are special plastic bags, they are not as durable as glass or plastic bottles. Sometimes, they are likely to be broken or leaked, and then let your baby nurse milk, you have to transfer the milk into a bottle or glasses.
For some kinds of breast milk storage bags, you have to use a transfer tool to pump milk into the bags. So you need to do more steps to finish the task and it is rather time-consuming.
Apart from that, the measurement of some storage bags is not very accurate. It makes you difficult when you need to calculate the exact amount of milk you want to feed your baby. To check its accuracy, you can use a measurement tool to compare.
How to Choose The Best Breast Milk Storage Bags?
Actually, it is not easy to distinguish the good and not good breast milk storage bags. To help you overcome this challenging task, I would like to share some key points when buying a breast milk storage bag.
Safety
Of course, you want to buy a qualified product, especially for the things related to the baby’s health, safety is the number one factor you have to take into account.
It is better to choose products from a reputable manufacturer and at a reliable store that has registered to buy baby’s products. When buying, you have to pay attention to its material; the best one is made of 100% plastic without BPA to make sure the baby’s health.
Size
You had better choose the storage bags which have the appropriate size with each pumping time because these bags are disposable. With too large storage bags, you have to pay more money and waste more garbage.
Durability
It would be a great idea to choose the smart storage bags, which are designed with the anti-overflow zip so that they are stable in the fridge.
When shopping online, there is not much information about the storage bags for you to consider such as the thickness, the quality, etc. Asking some experienced moms or read reviews online might be a smart method.
System
If you use a breast pump from one manufacturer and a storage bag from other brands, it will be harder for you to do. The good way is to choose some brands that have a full solution from breast pump to the storage bag. By this way, the milk storage bag can be directly attached to the equivalent breast pump, and you can quickly finish the task.
Price
Whenever buy anything, pricing is one of the most important things you need to care about. It would be great if you check both the quality and price of the storage bag whether they are affordable or not. In case the quality is equal, why don’t you choose the cheaper to save money?
Conclusion
Overall, choosing any product that directly relates to human health is always a serious problem and needs much attention. Especially when buying it for baby, you have to pay much more consideration.
If you have so much breast milk but your baby cannot consume all, the 110 Count Breast Milk Storage Bags might be perfect for you with large size. But if you want to organize the milk to store, The First Years Breastflow Storage Organizer might be the number one choice.
