This is the strangest thing... Well, at least for me.
I finally got my 2 preemies to breast feed with a nipple shield. They are both still in the NICU since 03/20/11. I can only breastfeed them at 8pm after work. Once I go home and pump at 11pm what I normally get with pumping is cut in half from my right breast.
Typically I get 4ounces from the left and 5 from the right when I pump. But at 11pm I struggle to even get 2 ounces from my right breast.
I though maybe it had something to do with me nursing the girls at 8pm, but I didn't nurse them last night and still at 11pm I have a decrease.
I have been exclusively pumping from 03/20/11 until I was able to attempt breast feeding 05/08/11, so now I breastfeed once a day and pump the rest of the time. The girls only started to actually breastfeed in mid June was the first I was able to get them to latch.
I used to pump at least 8 times a day, but once I got established and returned to work I am now pumping 6-7 times a day. It's been going ok for a couple of months until just the last couple of weeks.
