How To Choose Storage Bags?

Breast milk storage bags come with a variety of features, each catering to different needs. Here are some helpful variables to consider that can help you make the best choice.


When it comes to price, the more you buy, the less you pay. So buy in bulk to save. You can find really good deals on the internet these days, just be patient and try to find sites with free shipping opportunities.


It’s possible that at some point you may need to travel with your storage bags so it’s best to get ones that are thicker and more durable. Storage bags made from thick materials also protect against leaks or any damage that may happen as a result of thin packaging.


Filling your storage bag should be as hassle-free as possible, so make sure to purchase a bag which you can express directly into. Some manufacturers provide bags that come with a detachable opening or adapter that you can use when re-filling the bag.


Did you know that breast milk bags come in different sizes? Some smaller sizes are best for traveling or feeding smaller babies and some cater to larger infants. So check the size of the bag and purchase one that meets your needs. Also, try not to fill the bag all the way to the top, no matter how big it is. This way you’ll avoid leaks and wasting your precious milk.


To avoid milk spillage, storage bag manufacturers have come up with a variety of safe lids and seals to keep your milk safe. The most common one is a cap lock and others include secure screw caps and tie seals. Although it’s probably a good idea to avoid the latter, as they tend to tear and leak. The best option is to get a bag with a double zipper or the super convenient cap lock.


The milk storing process should be as convenient as possible and having a user-friendly bag facilitates that. So remember to get a bag which you can store easily with an opening that makes it easy to express milk into and transfer milk into the bottle when needed. Also seriously consider getting a durable bag as the thick material will protect against leakage, especially when the milk expands during storage. Lastly, make sure the bag is easy to label and write on.

Breastmilk Storing Tips

Keeping your breast milk fresh is vital to ensuring that your baby gets the best nutrition possible, even when you’re not around. Here’s how to have a well-kept supply of milk for your baby at all times.


Practice good hygiene by giving your hands a thorough wash before expressing milk into your baby’s milk containers. Also keep your containers sterilised and in clean condition always.

Pack in small amounts

Instead of binge-pumping all your milk at once, try pumping in smaller quantities. This way, you avoid the possibility of having a waste of surplus milk.

Keep it cold at all times

Put your milk in the fridge as soon as it’s expressed and packed. The best place for it is toward the back of the fridge where the temperature is at its coldest.

Clever Storage

Remember to put your filled storage bags inside the fridge only if you know that you won’t be using the milk within 24 hours. Leave a bit of space in the storage bags to make an allowance for the natural expansion of milk, which happens over time to stored breast milk.

Get Organised

There’s nothing worse than opening your fridge and finding your milk lost in the all the clutter. To avoid this, you can start by clearing some space in a specific part of the fridge that you’ll dedicate to only storing breast milk, and let daddy know about this area too so that he doesn’t store his beer cans in there by mistake. You could also develop a labeling system where you make each storing bag with the storage date to safeguard against spoilage.

Know when it expires

The longest that you can keep breast milk in the fridge for is up to 4 days and if it’s at room temperature, then it’s best to use it within 4 hours, or else it will spoil. You can keep milk fresh in the freezer for up to 9 months and no more.


Well, there you have it! All you need to know about the best breast milk storage bags. Hopefully this will help you to make the best purchase for your needs keeping in mind all the variables we mentioned above.

Make sure to get one that is convenient and safe for your baby to use (see: sterilized, BPA and latex free). It should be large enough to carry ample milk to satisfy your little one and durable enough not to spill under any conditions. Happy shopping and enjoy making memories with your precious baby.
