Breastmilk coolers come in really handy when you have breast milk and don’t have access to a fridge. Pumping or expressing breast milk is a time- and energy-intensive job, which makes it really frustrating when your pumped breast milk goes bad before it’s been used because it warmed up too soon. Before choosing a cooler, think about your budget, how much you will be pumping & how long you plan to store the milk in the cooler.

Do You Need A Breastmilk Cooler?

Before you invest in a breast milk cooler, ask yourself if the investment is worth it. The best way to do this is by considering how much breastmilk you will be pumping and storing at one time and if you will have access to a fridge where you will be pumping.

Most people find that investing in a durable cooler bag for work is best because they can store their breasts milk discretely for longer periods of time without worrying if it will go bad.

Another reason for a breastmilk cooler is if you are traveling and will need to be transporting the milk with you. Whether you plan to using it while traveling or to take it back home, a cooler will be essential.

How Long Will Breastmilk Last In A Cooler?

The CDC says that breastmilk in an insulated cooler with ice packs can be stored safely for up to 24 hours. Be sure to keep the bag out of direct sunlight to keep it cool as long as possible.

How To Keep Your Breastmilk Cold At Work Or Traveling

If you are traveling by car you can use a car fridge to ensure it stays safely cool as long as other foods you might be taking with you on your trip.

If you are traveling by plane choose an insulated cooler. If you are able to freeze your breastmilk in breastmilk storage bags then you won’t need to add an ice pack and you will be able to fit more milk in a smaller bag.

For keeping your breastmilk cold at work and do not have access to a fridge then choose an insulated bag or a thermos style cooler depending on how much milk you will need to store.

Different Types Of Breastmilk Coolers

Thermos Style Cooler: Holds breastmilk discretely. It also can be used for other liquids. A great part is it’s all in one with the pump and the storage. The only downside is that you won’t be able to store a whole lot of breastmilk.

Cooler Bag: Can be versatile and affordable depending on the bag that you choose. There are two different types of cooler bags, one you freeze the ice pack and set it in the bag, and the other you freeze the entire cooler. That could simplify things by not needing the added ice pack but could also take up a lot of freezer space.

Things to Consider When Choosing A Breastmilk Cooler

  • Size: Consider how much you will need to store when you are transporting your milk. Also, be aware that you might need more space as your baby grows and you will be pumping more milk.
  • Style: Do you want a cooler that is more low-key while at work or transporting it? Or would you prefer it to stand out so it doesn’t get lost in the shuffle at work or at daycare?
  • Type: Would you like a thermos style or insulated with an ice pack? There are also ones where you freeze the entire bag.
  • Budget: Investing in a high-quality breast milk cooler is crucial for minimizing your risks of wasting this precious resource and compromising the health and safety of you and your baby.
  • Performance: How long do you need it to be stored? Will it just be used to be transported to and from work?
  • Easy to clean: Do you want something that can be quickly wiped down or would you rather be able to do a deep cleaning with hot soapy water?
  • Versatility: Would you like it to carry other things such as snacks, lunches, or even your breast pump?
  • Carrying options: Do you want it as a backpack or a shoulder strap? Would you like it to be able to clip onto another bag or stroller?
  • Extras: Would you want something that needs to be charged or can be pre-chilled in the freezer? Would you want it to come with ice packs that fit specific bottles that you will be using?

Breastmilk Chiller Reusable Storage Container by CERES CHILL

Such an awesome and unique breastmilk storage container. You can choose to store your breast milk in the inner chamber for up to 12 ounces and just add ice water to the outer chamber to keep it cool for over 20 hours. Or you can store it in the outer chamber for up to 24 ounces and have the ice water in the inner chamber. I love that you can pump directly into the container to keep it simple.
