Surprise, surprise: I jinxed myself by asking if I should drop a pump session last week! (http://boards.hellobee.com/topic/would-drop-a-session#post-2316954)
Three days after I posted that, AF returned for the first time at 9.5 months PP. Since then, I'm pumping a few ounces less a day. AF was here for 5-6 days. I haven't bled for 2 days but my supply still hasn't returned. DD seems perfectly happy when she's nursing, but the pump isn't quite doing the trick the way it was before.
At this point, I'm not freaking out about it, but would love to hear your experience. If this happened to you, did your supply go up again until AF came back the following month? Or did it stay lower for good?
