Medela Quick Clean Microwave Sterilizer Bags for Bottles and Breast Pump Parts, Reusable Up to 20 Times Per Bag, Food-Grade Material, Made Without BPA, Pack of 12

At my hospital, we wash them with regular dish soap after every use. Then we have these microwaveable bags to sterilize them in. I believe that's done once per shift. We had a little water, it goes in for 3 minutes and steams, comes out and ready for use. steam bags These are the exact bags we use.

Our daughter is a former 26 weeker now 20 weeks adjusted. We still sterilize her bottles either using the Baby Breeza bottle sterilizer or the Medela quick clean bags. We have enough bottles to only need to sterilize 1x a day. https://a.co/d/080UEL7w
