I have been successfully breastfeeding for seven months now and all of a sudden the amount of milk I pump during the day is decreasing. I had a cold last week and thought that might be the cause, but am feeling better, not taking any medications and nursed as frequently as possible over the weekend and still am not pumping as much as usual. Today's session was almost half of what I have been getting. Has this happened to anyone else out there? What else can I do besides frequent nursing to increase supply?
