How long can you go without pumping? My twins were born really early Sunday and are in the NICU. They are only feeding one of them because the other is sick right now. They are feeding him 1ml every three hours. I had an emergency c section and I've been in so much pain. I've been doing every three hours and so far last night I got around 30ml when I pumped. I've pumped so much they have a couple week suply for now if they stay at 1ml every three hours. But everyone is making me feel like crap because I don't get to sleep and I hurt so much. I feel like I'm not healing at all from the c section. My mom let me pump around 1am last night then hid my supplies and made me sleep through the night. It's 9:30 now. Will not pumping hurt anything?
