Best Breast Milk Storage Bags

Whether you are planning on feeding your baby exclusively breast milk, or are planning on supplementing with milk and formula, you will need a great storage system for the breast milk.  This is especially true for mothers who are planning on returning to work but still don’t want to give up on feeding their child breast milk.  While there are many different systems for not only collecting, but also storing breast milk out there, one way has remained simple and trusted for years.  This is using breast milk bags to store the milk.  Unlike other containers, like jars and cups, breast milk storage bags can lay flat so that you can store more milk at a time.  While this may seem like a tricky task to perfect, it is actually easier than you may think.

How does it work?

In order to make sure that you are properly storing and serving breast milk, make sure to follow these steps and in no time you will be an expert!

Using a breast pump:

First you must start by pumping your milk.  Don’t worry about this weakening your supply of breast milk to actually feed your child.  A woman’s body is an amazing thing and in no time you will find that your milk supply will adjust to your ever changing needs.  Start slow by pumping in between feedings and in no time you will find that you can help your supply almost double over time.  

Transfer the milk:

When you pump you will either be pumping into a container or a bottle that will directly attach to your breast pump.  It is very important to make sure that whichever container you are using is completely clean and sterilized before using.  This is because you will then need to transfer the milk into a storage bag and you don’t want any cross contamination of germs or bacteria. Once you are done collecting the milk, very carefully transfer the milk to the milk storage bags.  Better quality milk bags will stand up on their own to make this process easier, but to prevent the bag from tipping over place it inside a cup to help keep it up right.

Label the bag:

Most breast milk storage bags allow you to write directly on them which make labeling super easy.  This is because these bags are often disposable so writing on them with a market will do no harm.  Label each bag with the date and time of collection.  This is the only way to know for sure that the milk you are using is fresh.  You don’t want to play the guessing game when it comes to the breast milk you will be feeding to your child.

Storing the milk:

When it comes to actually storing the milk, you have a few different options.  You can either choose to store the milk in your fridge or in your freezer.  A good rule of thumb is to store milk in the freezer but to also always keep a few fresh milk bags in the fridge for those emergency feedings when you don’t have time to thaw the milk.  When storing the milk make sure that you always rotate the milk from back to front depending on the collection date so that you are always using the milk in rotation.  This will also help you to not waste milk.  If you ware planning on sending your child to day care or to a relative’s house while you are at work, it is a good idea to even get a cooler.  This way you can send the frozen stored milk along with them wherever they go.

Serving the milk:

Once you are ready to serve your child the stored breast milk, simply remove the breast milk bag that is closest to the front and thaw.  You can either thaw out the milk directly in the bag in a pot of hot water or in a bottle warmer.  These bags will be tough enough to withstand high heat.  Just never throw them in the microwave because that is the quickest way to spoil a good batch of breast milk.  Once the milk is thawed and warmed up, you can throw away the milk bag and go about your day.  It really is that easy.

What to look for in a breast milk storage bag

If you have decided that using breast milk storage bags are the way to go, there are a few things you should always look for when shopping around.  Here are some of the key features to look for so that you know that you are getting a quality product:

  • BPA Free:

This is a good rule of thumb with any baby product.  Breast milk storage bags are made out of plastic, and BPA is often found in plastic items.  BPA is a chemical in the plastic then when exposed to high temperatures can release a certain toxin that can be harmful.  Because you will be heating up milk in these bags it is important to make sure that they are 100% BPA and toxin free.

  • Easy to label:

Many of the best breast milk storage bags will feature a space right on the front for you to write on.  Sometimes they will even have specific space for you to write the date and the time.  Having this right on the front of the bag serves as a great reminder to always label the milk right away before storing it.

  • Tear free:

You obviously want to make sure that you have found a breast milk storage bag that is strong.  This is especially true if you are planning on doing a lot of traveling.  Look for a storage bag that is made out of strong, yet flexible, plastic so that you know you are getting a durable and high quality product that won’t tear or rip.

  • Leak Free:

All breast milk storage bags will have a seal to protect the milk, but this doesn’t always mean that they are leak free.  Some milk storage bags even feature a double seal lock that guarantees no leaks will happen.  There is nothing worse that storing a week’s worth of milk just to find that they were not sealed properly and have to be tossed.  To prevent leaking and spilling make sure to store the bags properly according to the instructions.  While some bags can be easily stored flat, some work best if they are standing up straight.

  • Bulk purchasing:

A good rule when purchasing breast milk storage bags is that “more is more”.  It is better to have more milk bags on hand than not enough.  You don’t want to be wasting milk, or have to be forced to dump some because you simply don’t have enough bags.  That is precious food!  Some brands and styles of breast milk storage bags have either bulk purchase options or come in a large set so that you never have to worry about running out at the wrong time.

Here are some of the best breast milk storage bags that are available on the market today so that you can get well on your way to properly storing your milk!

Wrapping it up!

When you purchase one of the best breast milk storage bags, you are well on your way to being a pro when it comes to pumping and storing.  If you are a breastfeeding mother who worries about not being able to produce enough milk for their little one, have no fear!  Here are a few things you can do to help get that milk flowing:

  • Eat highly enriched foods

There are some foods that have been known to help with the production of breast milk.  Some of them many even surprise you!  Foods like rich oatmeal or dark chocolate have been known to increase production.  Try oatmeal cookies with dark chocolate.  They are not only a nice treat to have, but can actually do your body some good.

  • Mother’s milk tea

There are a few different types of tea that are floating out there that have been proven to increase breast milk production.  Most of these teas use a special blend of herbs and ingredients like clove and licorice to help kick start your system.

  • Continue to pump

One thing you can do is to continue to pump after you feed your baby.  Once your baby is finished eating, pick up your pump and extract every last drop.  Bodies are a beautiful thing; they will learn how to adjust.  When there is an increase in demand, there will be an increase in supply.

  • Treat yourself

Certain adult luxuries can actually help with the production of milk, one of these being red wine.  Red wine is high in antioxidants which have been known to be a natural stimulate for breast milk production.  Because of this, winding down at the end of the night with a glass of red wine is actually encouraged.  If you are not into wine, you can also achieve the same result with dark beer.  Just make sure to not over do it.  When it comes to trying this trick, less is more!

  • Find support

The biggest resource available to parents that is often times overlooked is parents.  Chances are you know someone who is having the same trouble as you.  Reach out!  If you don’t know anyone with children, turn to the internet.  There are a ton of support groups available out there that are judgment free.  Worst comes to worst you may even meet a new supportive friend.

  • Consult a specialist 

If you still feel like you can’t keep up with your child while also trying to store milk, check with a specialist or your child’s pediatrician.  Chances are they can help assist you while also helping you to pin point the problem, if there is one.

  • Take care of yourself

Being a parent is hard work.  To ensure that you are taking care of your child, it is important to first take care of yourself.  Find time to rest and relax and make sure you are staying hydrated and well fed.  You would be surprised by how much change you can see by just giving yourself a rest day.

  • Don’t’ get discouraged

If things are not going the way you planned, or you are unable to produce enough milk to store, don’t worry.  There is no shame in trying your best and not getting an ideal result.  So many mothers are so hard on themselves, especially when it comes to breast feeding.  The important thing is that you set out to do the best for child, and that is what really counts.

Breast milk storage bags really are an amazing invention.  They not only help to make storing breast milk easier, they also have many different other uses.  Many parents continue to use breast milk storage bags to store baby food.  You can easily fill these bags with homemade pureed baby food and store them right in the freezer, the same way you would breast milk.  This is because these bags are already sterilized and ready to use.  You can feel safe filling them with any type of food your baby will eat.  Some parents even continue to use these bags for their own food.  The options really are endless.  The most important thing to remember when it comes to storing breast milk is to keep an eye on the date and time stamps.  A good rule to remember is that milk that is stored in the freezer can last up to 3 weeks, while milk stored in the fridge will last 3-4 days.  When in doubt, use your best judgment.  Good luck and take care.
