Does anyone still do this? Store their used pump parts in the fridge and use for a few sessions? With my last pregnancy my doctor recommended it to save time, and my son was fine. But now I am reading that the pump parts MUST be washed every single time. I ordered extra parts but they won't be here for a week and I am not looking forward to washing my pump parts every three hours om top of feeding baby and pumping! At this rate I am getting a half hour sleep at a time!
