ugh the pumping and breastfeeding has been my nemesis!!! My only advice is what I've been told but it hasn't really helped me, maybe it will for you.
You have to pump literally around the clock every 3 hours including the middle of the night to increase your brains concept of "supply and demand".
Try Fenugreek or other "More Milk" "Mothers Milk" type herbal supplements.
Take Reglan (prescription but beware of the depression, see my other post on PSA for moms)
Eat Oatmeal, lots of oatmeal.
That's all I've got! GL!!!
Actually, you don't necessarily have to pump around the clock. It all depends on your body and its ability to make breast milk. I pump 5 times a day (6am, 10am, 2pm, 6pm, 10pm) and get b/n 40-50 oz with 7-10 per session. Honestly, I am just blessed with super boobs and don't do anything out of the ordinary.
When I had DS, I did the pumping every 2-3 hours around the clock, ate oatmeal and drank tons of water and ended up with about the same amount of milk as I do now. So, I don't know if any of that actually helped me or not but I was beyond exhausted and gave it up after only 5 wks. This go around it is a billion times easier b/c I don't pump all that often and the stress is not there so I will probably be able to go much longer than I did last time.
I exclusively pumped for almost 8 weeks. (Now he is back on the boob).
Pump every single time Lo eats. During the night I would pump when he ate a bottle, during the day starting around 6a.m.(or when LO got up) I would start pumping every 2 hours to get my supply up. Pump for atleast 15 minutes. (Even if there isn't any milk coming out) It is all about supply and demand! You pump and it will trigger you to make more milk, just like if LO was eating straight from the breast.
