How to Choose the Best Breast Milk Storage Bags

As an alternative to breastfeeding, using storage bags is a perfect way to keep your milk safe until later use. When you are shopping for the best breast milk storage bags, you should consider your needs and how the bag functions. From first time moms to those with many children at home, every mom wishes for the best for baby, and keeping breast milk at its freshest and safest is extremely important for baby’s health and well-being

Compatibility

Since you will be pumping to store your breast milk, you will need to consider the make and model of pump you are using and whether the breast milk storage bags you are purchasing will be compatible to hook up directly to your pump. Not all bags will work with all pumps which means you will need to pump into a separate sterile container and pour your milk into the storage bag. This extra step means you are risking spillage and loss.

Freezer/Fridge Storage

Because you will have to keep your breastmilk in the fridge or freezer, depending when you will be using it, you will want to make sure it stores well for the required time. Some bags do not store in the freezer for extended periods. Also, some storage bags are bulky and take up a lot of much needed space in your fridge or freezer. This is important to consider when buying breast milk storage bags.

Capacity

You may think more is better but that is not necessarily the case with breast milk storage bags. If you are only able to pump a little each session, then you won’t need a larger bag. It is not recommended to mix separate pumping sessions with each other so you will need a fresh bag for each round of pumping. This could mean a lot of storage bags in your fridge or freezer, so larger capacity may not be ideal for your situation. There are different sizes available on the market, so consider your own needs.

Special Features

In order to gain your business, each company will try to offer something special about their storage bags. These features will mean different things to each mother, and will vary in importance depending on what is most fitting for your own lifestyle. Maybe you want a quick, easy to use bag or one that lays flat. These are various features you may encounter when shopping for the best breast milk storage bags.

Affordability

This doesn’t necessarily mean look at the overall price and that means it is affordable. You should consider what you get for your dollar and if there is more value involved with each storage bag. Perhaps you will be willing to pay a little extra for convenience or for size. Affordability may mean you are getting more bags than with other brands, or it could mean they are most affordable for your pump. This factor is very individual to each mom, but should be taken into consideration when purchasing storage bags.
