I recently started dabbling in pumping to build up a stash and I'm having major problems getting a let-down, which is a let-down (ha! bad pun intended). Sometimes I manage to get one let-down, but not always, and I never get two. I utilize the "stimulation" phase in PISA, but it doesn't really help. At times I can tell there's milk readily available, but it just won't come out. So frustrating!!!
How do I go about figuring this out? I'm going back to work in 2 months and I'll be pumping during the day, so this has me worried.
