Having read that I still don't understand. If milk production is driven by supply-demand now, then surely pumping till empty after the morning feed and 1.5h after the BT feed should in theory increase production. I see the opposite effect and have just spent 1h pumping and hand expressing to only get 70ml of milk (DD needs 150ml for her DF).
Also since I have always had these pumping sessions at these times, surely the body should keep up production at the same times once supply is established?
It's always been WU feed, pump 150ml, BF throughout the day, 9.30pm pump 100ml
I used to use 150ml for the DF and then freeze the rest. Over the last month or so DD has still been hungry after the BT feed and I have been using the 100ml left over to top her up. Then the pumping dropped to 100ml in the morning and 90ml at night and this morning I only got 100ml pumping and now 70ml....
Yesterday and today have been so bad supply-wise I am starting to stress about satisfying DD at the NF.
I'm eating well and drinking enough (2.5l a day), sleeping as much as possible, eating oatmeal every day, drinking lactation tea, what more can I do?

BF has been such a struggle and we are almost at 6mo, I've been over the moon that we got this far and was hoping to make it to the end of the year. I'd hate to stumble now.
