Just because it didn't work out for you with baby #1, doesn't mean it won't work out with #2 :) I have lots of friends who had a lot of trouble BF'ing their first children, so much so that they just stopped, and when baby #2 came around, they had no problem at all! :)
If you're nervous about it, I would recommend trying to talk to lactation consultant beforehand, maybe one that is known for good results? When we were in the hospital, the lactation consultant we had was terrible. She would just look at the baby, and my breast and say everything looks good, then she walked away. She also just kept repeating that it shouldn't hurt if I was doing it right and that was that.
I was seriously thinking if this was what breastfeeding was there was no way I could keep doing it. When we got home, I called another lactation consultant. She came to my house. She assured me that for some women, it is very painful for the first while (like 2 months for me), but it gets better. She was able to show me lots of techniques that worked for DD and I, and assured me that though it feels like DD was not getting enough, just keep at it, and I would produce more, and as long as DD was gaining weight, filling enough diapers, then everything was fine. Eventually everything fell in to place, and after 2 months, the pain was gone, and my supply came in. I do not have big breasts, and this size of your breasts really doesn't have much to do with it.
I wish you good luck with baby #2, I hope it's the complete opposite for you next time! :)
