Just back to work after 7 weeks of wildly successful, pain free nursing. Even introduced a bottle & pacifier at 5 weeks with no issues. Now that I am pumping with the Medela Symphony (hospital pump) 4 - 6 times a day x 10 - 20 min each & the base of my nipples are incredibly raw. I pump that much at work because I work 10 - 12 hour days. Have only been back to work 5 days, noticed the soreness on day 3. was using the lansinoh lanolin but seemed to make the base of the nipples stickier & hurt more. Started using left over mama bee belly balm & that eases some discomfort while pumping but still sore. Am using 27 mm breast shields. Also have the setting on low (3 drops appear on screen in stimulation phase & 5 bars appear on letdown phase). Any advice?
