I have a 3 months old baby and I am returning to work next week. I am planning to pump 2-3 times per day at work while breastfeed when I come back home. My question is, what's the best way to clean the pumps in between the pumping sessions? It may be awkward to clean the stuff at the kitchen at work. I bought the medela wipes just for the pumps but haven't tried it yet. Wonder if the wipe would be enough to clean the small holes in the pump. I am afraid that bacteria will grow if I don't clean it right.
