Milk storage bags are an absolute must have if you want to keep things in order. And save money in the process. If you are breastfeeding your baby then you know that baby can eat a lot. I mean a lot of milk! So, that means you’re going to have a lot of milk lying around.

Storage bags make collecting, storing, and freezing breast milk a breeze. Use these bags to store expressed milk at the same temperature breast milk normally would be kept at (a few degrees lower than room temperature) and they’ll need to be replaced every 2-4 months. If you’re reusing bags, use them within a year!

Our rating: 9 / 10

Unimom 60 Breast Milk Storage Bags

Check Price on Amazon

Pros:

  • Does Not Leak
  • Disposable and Refillable

These are the easiest to use, most convenient bags for freezing your breast milk. The shape of ll bags fits most breast pumps without a problem with minimal air pockets. They accommodate stored milk from full size bottles to breast shield fasteners. These bags are reusable and easy to fill, dispense, and store. Besides being easy to use, they are also one of the most thorough and well constructed breast milk storage bags. They come in petite and large sizes. There are 24 large and 37 petite bags in one box. This is enough to last you a long time while feeding baby.

I had no problem with these bags leaking or not being able to close them easily enough. The company calls this zip-top closure and it really does look as efficient as is sounds. They are also sturdy enough to last for a long time and can fit into freezer bags without a problem. they are easy to clean out as well. These bags are leakproof, but I wouldn’t necessarily say they are 100% spill proof.

5. Kiinde Twist Pouch Direct-Pump Direct-Feed Twist Cap Breast Milk Storage Bags

Our rating: 9 / 10

Kiinde Twist Pouch Direct-Pump Direct-Feed Twist Cap Breast Milk Storage Bags

Check Price on Amazon

Pros:

  • Great Quality
  • Thick and Durable
  • Convenient and Convenient
  • Versatile

Cons:

  • Larger and Bulkier
  • More Expensive

The Kiinde pacifier system is great, but I also like their breast milk storage bags and heat-sealing kit. One of the biggest obstacles to working mothers is the challenge of storing breast milk safely in a way that’s also convenient. Kiinde has worked to perfect the breast milk storage bags to accept a bottle adapter, which makes it ultra simple to pump and store breast milk or even add formula. The twist cap is also a nice feature that makes it easy to open the bags without spilling. These bags also work with microwaves, refrigerators, and dishwashers.

These are my top picks for a good quality pacifier, but I don’t want to be accused of playing favorites, so here are some other good ones.

Tommee Tippee pacifiers are great as well. These are the ones I like best. If I were buying pacifiers, I’d check out these three types.

Medela Pump in Style Advanced Breast Pump

Check Price on Amazon

Pros:

  • Included Backpack To Store Cleaning Pieces:
  • Double Electric Breast Pump:
  • Portable Battery Pack:
  • Portable and Convenient:

Some people believe that the Medela PISA is worth it, while others insist that it is not. Here is what my investigation found. The handheld pump offers more power and can give a better flow than a hand pump. This means that your nipples should be less sore in the long run. The best part is that this unit offers suction that is on par with a hospital grade pump. This is something that not a lot of pumps can do. This pump is safe for nearly every woman. The exception would be those who have pre-existing medical conditions that could be made worse by hand pumping. If you have any issues, just talk to a doctor before using the pump.

What I really like about this pump, besides the convenient backpack, is the speed settings. There are four different speeds that can either be adjusted or locked in place. This is perfect if you have a baby that will be using a bottle that does not have a slow flow nipple.

  • The best way to store breast milk
  • Eco friendly and free from BPA

Cons:

  • Expensive
  • Not as pre-sterilized as some others

Going through the hassle of sterilizing full, breast milk storage bags before you use them is obviously out of the question.

The medical grade durable bags included are thick and have good strength, meaning they can be submerged directly into boiling water to sterilize them.

  • No batteries required
  • Small enough to fit into your purse

Cons:

  • Suitable for occasional use only

The American Academy of Pediatrics recommends breastfeeding your baby exclusively for the first six months. As a new mother, you probably have enough to think about without adding bottles to the mix. If that’s the case, you might consider a manual breast pump.

The Philips Avent Manual Comfort Breast Pump is one of the most popular hand pumps on the market. It’s easy to use, compact, and inexpensive.

Like other manual pumps, it’s simple in design. It uses one silicone flange and two flexible and soft-touch breast shields. You put one breast shield over your nipple and the other over the top of it, create a seal, then squeeze the handle while the breast shield gently pulls on your nipple in order to create the suction that you need to get the milk to flow.

Frequently Asked Questions (FAQ)

Which breast milk storage bags are best?

There are not many important differences between brands, so you can always choose whatever storage bags your hospital has available for free (or can order). However, I have found that the Lansinoh Breastmilk Storage Bags are the easiest to use. Most breast pumps have a specific way you need to fill them up. The Lansinoh bags are designed so that you can connect your breast pump directly onto the bags. This makes filling your bag much easier and it helps avoid spills while you’re doing it.

If you aren’t pumping, you can use any of the standard bags.

Does it matter what breast milk storage bags you use?

While you’d be forgiven for thinking that the quality of your storage bags doesn’t matter, as long as they don’t leak, this is not correct.

Breast milk storage bags are a little different than your typical ziploc bags. They’re made from a thick plastic and have a built in sealing mechanism to prevent contact with air. What this means is that these bags are intended to be used for a longer time period and need to be able to withstand the constant pressure of the built in sealing mechanism at the end.

Low quality bags might not be able to stand up to this constant pressure and might leak when stored over long periods of time.

On the other hand, high-quality bags are thick and sturdy and can stand up to extended periods of use without issue.

How many oz of breastmilk should I freeze per bag?

Every bag or bottle can hold up to 8oz of milk. This total milk capacity works out to hold anywhere from 9 to 12 ounces per bag depending on the circumference of the neck. If you have small bags you probably won’t put this much into one bag. If you have large bags and bags with nice wide necks you can put 8 oz in per bag.

How long are breast milk storage bags good?

Freshly expressed breast milk will stay fresh for a much longer period of time when frozen. The blood spots will disappear and it will taste just like it did at the time of pumping.

Some mothers choose to use breast milk storage bags and store the milk in the freezer for several days before it is used. You can also freeze milk for up to three months into another container and then pour it into an ice cube tray when ready to thaw for the baby.

Aside from the fact that the milk may thaw quicker in the breast milk storage bags, the only drawback is the labels on the bags may not be visible after the milk had been frozen.

Both containers are just fine, so your choice depends on which you prefer.

Conclusion

In this article, we look at the best breast milk storage bags for mothers with babies who like to be breastfed during the night. We believe that it is crucial to put quality first and you would be hard pressed to find a better option than these bags, which are also quite affordable compared to the rest.
