My LC mentioned to me that the CDC now recommends that pump parts be washed after each pumping session and so storing them in thr fridge between pumping is not recommended. She said bacteria can build up on the parts ib thr fridge. I looked online and saw the guidelines were released when a premature infant got an infection but in that case the pump parts were left soaking in water for several hours.

I am exclusive pumper with 2 older kids and the idea of washing my parts after each pumping session is just too much for me. What do you pumping moms do?
