I am actually worried about this too!! I am struggling to produce 8oz in a full day of pumping, 3-4 sessions. Luckily my mother is making it stretch but I worry what will happen when I get closer to one year. Baby is about 7.5 months right now... Wish I had an asston of milk sometimes!! I get 3.5 weeks off after this week and I am hoping it will do good things for my supply, is that wishful thinking?
