I had an elective c section for extended breech too, and I had problems starting out. I got my supply up by: Ihad an alarm every 2 hours even at night and made myself pump, and I also pumped one side while she fed off the other. I took fenugreek as well, but the regular pumping is the main thing - don't stop pumping when it stops coming out either, try turning the pump and you might get another duct let down milk. Sometimes it really hurts to pump that often. Try and have your baby right next to you when you pump as well, as it helps. You can't skip pumping sessions though, it really has to be that often if you want to increase your supply. My supply's fine now, and I'm back to feeding directly from me. I still pump when she wakes up in the morning though, because she sttn now and my breasts are so engorged I pump while she feeds and freeze that milk. How often are you pumping? xxxx
Edit: I only answered Mrs Amillion, sorry OP.
OP: Have a look on this site it helps you work out how much expressed milk to feed by the baby's weight xxx
