Re: Feeding on one breast through the night?
I wouldn't do it, either. By allowing the unused side to fill up and go all night long with no stimulation, you're telling it to reduce production. The milk it's making? The fullness tells your body "No thanks, not needed". I think it would be better to offer both breasts overnight, and then pump both in the morning.
Can you tell us more about the pump problems you're having?
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
