An easy way to organise the stock of your breast milk is to use milk storage bags.

There are several amazing options for breast milk storage bags on the market today. Most, if not all of them, contain convenient easy-to-use labels that you can write on. To be honest – storage bags simple to use and are not the most complex items on earth. There are, however, some very important differences between them. Whilst they may seem similar, they all have subtle differences in their materials and design which result in huge impacts on their reliability and performance.

A good storage bag for breast milk:

  • should not leak;
  • should be easy to fill and empty;
  • can easily be stored in a freezer (preferably in as flat a position as possible, allowing you can stack them on top of each other).

These are the most important features. There are also some additional qualities that can make one storage bag more appealing for you such as biodegradability, ease of labelling or clear markings for the volume of milk inside.

Why people use breast milk storage bags?
  • they take less space in the freezer than a bottle;
  • milk thaw faster in the bag (an important factor when holding a hungry screaming baby).

Benefits of using breast milk storage bags

Storing breast milk in bags can bring lots of benefits, not only for you but also for babies. The experts speak of five fundamental reasons that make the use of these bags prevail over other storage devices and are:

  • It facilitates the spill thanks to its special design.
  • They are carefully designed for storage.
  • Most modern breast milk storage bags are free of BPA.

Additional tips for proper breast milk storage:

What to consider when choosing

Before choosing one, it is essential that you look at a series of qualities that will make your selection more accurate and you can ensure that you have the right model on hand and that it suits your needs, so before buying, it is essential that you look at these details:

Durability

This quality is measurable with the thickness of the bag. If your purpose is to store the milk to freeze it then you should make sure it does not leak. A thick bag will be more durable than a thin bag.

Harvest

Generally, these devices are filled through two systems. Or you pump directly into the bag, or you do it in a bottle and then into the bag. You should go with the one you find most comfortable and practical.

Size

It is advisable not to fill it beyond its capacity because however resistant they are if you overlap it will be more prone to leakage. You should check which of the sizes works best for you. They come in sizes of 4 ounces and 6 ounces.

Seal

You should avoid union seals or labels because they are more prone to leaks. I recommend screw caps or double zippers.

Easy to use

A bag that is not difficult to fill and that is thick and with a pouring spout will come in handy. Do not complicate your life.

Safety

Given the delicacy of the content, you must ensure much of this point. I recommend you go with a brand of remarkable reputation with all its certifications.

System

This refers to storage. The good is that you get everything in one. Bag and breast pump to do all the work at once.

Pre-sterilized

You must make sure that they have this feature. The opposite can be an unnecessary risk to the health of the baby or a lot of complication for your lives.

Measurable

Babies usually drink certain amounts of milk, so a bag in which you can measure the content is a very useful idea. So you can pour into the bottle only the amount that the child will drink.

Foot function

Since they will surely go to the refrigerator or freezer, the fact that they can sustain themselves without having to put them in a horizontal position which carries risks of leakage. This quality is essential because you can place it in the fridge or countertop without worrying about falls and spills.

Compatible with a pump

Some bags come package all in one, but if it is not the case you must make sure that the selected one is compatible with your milk extractor pump.

Ready freezer

Given the storage levels, you have designed for these bags the most advisable is that you decide for a group that is resistant to cold and able to get into the freezer. It will facilitate your life, storage, it will last longer and you will be calmer.

It is sold in a dispenser

This allows compact storage and undoubtedly takes away from problems and complications
