I'll admit, buying the Ceres Chill was a spontaneous 4am breastfeeding decision, but I'm REALLY happy I made the purchase. The Ceres Chill makes it so easy to bring milk with me anywhere I go. And I think it's great that I'll be able to use it long after my breastfeeding journey. This thing keeps liquid COLD! It gives me great piece of mind to bring a few extra ounces of milk out with me, and I love storing my milk in the inner chamber in the fridge!
