Breast pumping mother I have a question: the little white medela membranes. Are they single use? Thy only supply 4. Do I toss after every use or can they be rinsed?
All Medela parts like that are re usable. Just make sure you wash and sanitize well. I always washed mine and put them in sterilizer, or if I had my lazy days I would wash and then put them in the Medela microwave sterilizer bags! Lol
