Are Breast Milk Coolers Safe For Daily Use?

Of course, they are! Most breast milk coolers come with separate ice pack chambers. So, all you need to do is pour the breast milk in portable containers and then put the containers inside of the breast milk cooler. This way, the breast milk does not come in contact with any external elements, and the lowered temperature keeps it stable from spoiling!
