Breast milk is a precious gift from God that offers all the essential nutrients to your baby which are much required in their initial stages of growth.

However, like all other fresh milks, breast milk goes bad very fast once expressed out. Thus, a good cooler bag is required to make sure that the milk remains fresh and lasts long even if you travel, fly regardless of the weather. In this article, we will mention different and pretty affordable cooler bags that will assist you in easy transportation of your breast milk that is frozen or freshly pumped.

One of the biggest issues faced by exclusively breastfeeding moms is how to carry breast milk when working, traveling or flying with or without the baby. You need to guarantee that your breast milk either frozen or fresh does not go bad whenever you are moving either from work, or traveling by a car or flying.

Luckily, with the variety of best cooler  for frozen breast milk available widely, you do not have to worry about this anymore.

For how long can frozen breast milk stay fresh?

Breast milk once chilled (not frozen) usually remains good for up to five days. In case of frozen breast milk, the thawed breast milk can be kept in the refrigerator for up to 24 hours after de-freezing.  However, it is of utmost importance to note that it is not recommended to re-freeze the breast milk once defrosted.

And since microwaving destroys nutrients in breast milk, you should never try to thaw or heat breast milk in a microwave oven.
