If you have a Medela breast pump, this kit offers a way to collect, store, and serve your breast milk in one container. The set includes four 5-oz. plastic bottles that attach directly to your Medela breast pump. When you've finished pumping, cover the bottles with either the two-piece plastic discs for short periods of storage (an hour or two) or the solid airtight plastic lids for longer storage. The airtight lids minimize oxygen exposure, so you can store your breast milk in the refrigerator for up to seven days, or in the freezer for up to six months. Also included are four bottle nipples and nipple caps. The caps also work great as small drinking cups for an older baby, or for mixing breast milk with baby cereal when you're on the go.
