Ouch. I am an emotional wreck because of the nipple pain (mainly the left one, but the right one aches when not in use, too), and feelings of complete inadequacy and moo-cow-dom. Evan has already gained a whole pound since birth, so I know he's getting something good out of breastfeeding, but I am constantly miserable.
My left nipple is a little flatter than the right, so he has some trouble latching on, even when I pancake it. I'm afraid to introduce a nipple shield, but am starting to think that would be better than avoiding letting him nurse on that side (it's not so bad laying down, so when I need to, we go and lay down). I have breast shells, but have not had much luck with them. My breast pump seems to draw my nipple out, but not until I've made a significant milk donation to it, and by then Evan is quite angry from waiting.
I have 4 different nursing bras, and I hate them all.
The "good" news is that we've already been much more successful with breastfeeding than I was with DS #1
Somebody tell me it's worth it.
