I will be going back to work part time in a few weeks. I have been pumping since I first started bfing my ds because of engorgement issues. Right now, I pump for about 5-7 minutes and am able to get 3 to 4 ounces in that time. However, I am worried about that not being enough for him for much longer. Should I pump for a longer amount of time (say 10-15 min) every time that I do pump? I just want to make certain that I pump enough for his daily bottle and that I still have enough for him to nurse. Any help would be great. Thanks!
