I had a boy by c-section, 8lbs10oz. They thought he was a little jaundiced and gave him formula too! I was completely adamant about breastfeeding and read so much on the subject. It helped that my husband was totally on my side and encouraged me even through the toughest times. Breastfeeding is hard in the beginning. My son is 3 months old now, and it seems like ages ago we had difficulties... now it's really, really, painfree.. easy! (not to mention all the other benefits: $) One major thing comes to memory. Keep calm. Even at the toughest moments, a deep breath (smell the flowers) and a quick exhale (blow out the candles) did the trick! That will calm you, encourage another let-down, and keep you going (works for pumping too). My motto early on: Just one more feeding, Just one more feeding...
If she is screaming and really fussing to the point she won't latch (even though you know she can, cause she did it before!), you've got to calm her down first. Have you heard of Dr.Karp cuddle cure? He wrote, The Happiest Baby on the Block. Excellent read for babies less than 3 months. You can calm any baby with his suggestions. Google them for more info, but they are:
1) swaddle (tight!) even if she resists;
2) side/stomach (face baby in toawrds you);
3) shhhh (make a constant sound louder than her cry... like ssshhhh, ssshhhh, shhhhh or whatever works for you);
4) swing (rock back and forth quickly, or jiggle her so her body's moving);
5) suck (offer a pacifier, or a finger).
After these things are done in order, you should notice her calm down. A reflex might kick in again to cry, but just keep swinging and shhhing. Once you are both calm, try the nipple again. Nursing walking around worked great for me (except DS is now 20 lbs! biceps are toned!)
Once you get her latched on, try breast compressions to keep her there. When she stops sucking, squeeze your breast (4 fingers under, thumb on top) until she starts sucking again. A baby who is getting milk won't fall asleep at the breast or fuss, cause there is milk there to taste. Keep this up until you have your 20-40 minute feeding. It works! In the beginning, I wore my hospital gown at home for the first two weeks, then was pretty much topless after that for awhile. For newborns, I would basically feed them when they are awake (unless they are quietly awake). I remember a nurse telling me upon discharge, no matter what happens, feed the baby - you can't go wrong if you just feed the baby. You will get to read her cues better as you continue. Things didn't really change for me and my son until about 7-8 weeks...
It does get easier. Bfing your baby is really the best thing you can do. It is much easier than pumping. When you are ready to go to daycare, you'll need to keep your supply up for pumping then, so keep putting the baby to the breast in order to get there.
You're doing a great job so far! There are lots of ladies on this forum who provide excellent advice right when you need it, so take advantage of them!

Keep going mama!
