I am currently exclusively pumping due to having twins in the NICU born at 25 weeks. I have developed mastitis 2x in the past 6 weeks. The first was at 2 weeks and then again this past weekend. I am pumping every 2-3 hours during the day and 3-4 hours at night. I am having a hard time emptying my breasts completely. I have been using a microwave hot pack prior to pumping and massaging while pumping. My biggest concern is that my milk supply has greatly decreased and I am worried I won't be able to supply enough for my boys. Any advice would be greatly appreciated. I currently use a medela symphony pump and have been thinking of purchasing the pumpin pals. Thank you for any ideas, suggestions and support.
