When I wash all the pump parts and bottles I sometimes have to reuse them when they haven't completely dried. Should I dry them with a paper towel? Will the little driplets of water inside the bottles harm the breastmilk? When I pump I leave a bottle out in room temp for my DS's next feeding, which is usually in the next 2 hours. I am just afraid that the water driplets with help bacteria build up in the milk. I know this seems silly (I am in no way a scientist!). I am I over-worrying about nothing?
