Breastmilk Bandit is an easy re-usable way to store and organize your freshly expressed milk. Breast milk is safe stored in the fridge for up to a week. Fresh breast milk has living white blood cells and stem cells that help protect against infection and disease. While frozen breast milk is great, fresh breast milk is even better for your baby! Breastmilk Bandit's Breast milk Bands allow you to label your bottles easily. They can be purchased in a starter set of 7 bands with each day of the week or refill packs with 2 bands each for Monday through Friday, the most popular pumping days for working mamas. Never forget what day you put your baby's milk in the fridge again! This brand new system is affordable and economical because it is dishwasher safe and reusable. And how cute is it for your little nursling to have his special bottle marked Mommy's Milk - Sunday to take to the church nursery! Fits most bottles such as Medela, Ameda, Lansinoh, Hygeia and more.
