You can store your breast milk for up to six months in a standard freezer or up to one year in a deep freezer in these pre-sterilized high-quality storage bags by Medela. Made of medical-grade nylon, these bags are ultra thick, which helps preserve vitamins and minerals during freezing. They attach to any Medela breast pump, so you can pump right into the bag; there's no need for extra pouring. They seal at the top with a twist tie and include a built-in pour spout, so you can easily transfer thawed milk to a bottle. Each bag is marked in ounces and milligrams to help you measure how much milk your baby is drinking
