I try to let the pump go for 20 minutes.

I pump every time DS eats. I also try to get in one extra session a day to stimulate further production.

Right now I produce enough for his feedings from each pumping session. My middle of the night pumpings I produce 2.5 oz extra each time. My *extra* session I usually only pump 2 oz. I haven't noticed any real increase in my production over the past week (since I've been pumping).

Any tips?
