The most common item used when you travel with your baby is the cooler for breastmilk. This can be a lifesaver in such situations.


However, to get all the benefits that such a cooler can offer, you need to invest in a high-quality product.

This guide will walk you through what to look for, what are the best coolers on the market and their pros & cons.

Why do we need a cooler for traveling with breastmilk?

Frozen breast milk bags

Traveling with breastmilk for more than a couple of hours is risky. If you don’t store your milk in proper conditions, your milk will not have the conditions it needs to conserve its main nutritious properties. Here are a few reasons why you should use a cooler bag when you travel with breastmilk!

  • It keeps the milk at the optimum temperature to not go bad. Breastmilk goes bad in four hours at room temperature. In the fridge, it can stay good between four and eight days and in the freezer for six months and even nine months. But what to do if you are not able to put the milk in the fridge or freezer? If you are traveling, you need a cooler to replace the refrigerator or the freezer to keep your milk cool enough not to go bad.
  • A cooler helps you store your breastmilk too. Such a cooler bag is a vital storage option, as well. When you are traveling, it might be challenging to pack the breastmilk if you don’t have such a bag. Plus, in some of these bags, you have enough space to place your breast pump, pacifiers, and some wet wipes or diapers as well. A cooler bag will help you keep your breastmilk and the accessories you need for it safe and well organized.
  • Such a cooler bag might keep your breastmilk warm too. We say “might” because not all the cooler bags you will find on the market have this capacity. But if you choose a bag that can keep your milk warm as well as cold, you will have a double advantage. You can keep your milk at the right temperature so your baby can drink it any time they want without you having to warm it up.
  • However, keep in mind that this can be a useful option for short trips or daily use of such a bag. If you are planning to go on an eight-hour flight, you will not be able to use the warm feature because your breastmilk will go bad if it stays at room temperature or hotter temperature for more than four hours.

What to look for in the cooler?

If you never purchased a cooler bag, you might wonder what you should keep an eye on when you need such a product. Here are the main features your cooler should have so you can make the most out of it!

Spacious cooler bag

  • Size of the cooler: This is definitely one of the most essential features. You want your cooler to be big enough to accommodate the bottlers you use for your baby. A cooler that can hold 8 oz bottles will also hold 5 oz bottles. But it can be very frustrating to have a cooler that can hold 5 oz bottles when you use 8 oz bottles for your baby. How many bottles can fit in your cooler is also very important. You can find coolers suitable to carry two, four, or six bottles.
  • Useful Features: Some cooler have extra pockets so you can bring diapers with you. Others have a separate container for your breast pump and its accessories. These additional features can turn out to be very useful, especially if you are planning to keep the bag with you as you are traveling with your baby. If you check in the bag at the airport, these extra pockets might not help you much. But otherwise, they can be a lifesaver if you need a diaper change when you are on the road.
  • Ice Packs Ice packs: Another important feature is if the cooler bag has or doesn’t have ice packs included. If your cooler doesn’t come with ice packs, you will have to invest in them separately. But a good cooler bag will come with reusable ice packs that will help you use the cooler right when you receive it.
  • Cooler bag material: The material of the cooler bag is essential for several reasons. First of all, you want it to be well insulated with a leak-proof lining so your milk will stay safe and at a constant temperature. Secondly, but no less critical, you want a bag that is made of non-toxic materials. Choose one that contains no BPA or other harmful chemicals. You want to be sure that you use the safest and best cooler bag to store your baby’s breastmilk!
  • Frozen milk option: If you are planning to travel with frozen milk that you intend to maintain frozen, you will need a different type of cooler, however. The best ones to use in these conditions are the coolers that come with a gel wall instead of ice packs. This is the only difference between regular coolers and coolers that are great for frozen milk. The gel wall will offer the proper insulation and maintain lower temperatures than other cooler bags.
