Hey girls! My left breast doesn’t respond to the pump well at all. Tonight my baby slept thru the night for the first time so I’m currently pumping while baby is still asleep. I got 4oz from the right but my left will barely give 2oz. I know there is more milk in there because of the pressure. I’ve manipulated the settings and done massage and can barely relieve it. I’m nervous for when I go back to work since I won’t have baby around to help! Any advice? Are manual pumps helpful?
