I have to agree with what has already been said, ATTACHMENT and & position (sounds like real estate doesn't it?)

I had nipple trauma for the first 3 days, I made sure the midwives helped me every feed, and still I had pain, finally the trick that worked was seeing a video with the lactation consultant, and I saw that you had to point the nipple towards the babies nose in order to get it in, (won't make sense until you are there with baby) anyhow somehow I got it, how to do it and from then on it was much better.

My advice buy a tube of lanisol (oure lanolin) because I am not sure anyone doesn't have a bit of nipple trauma at some point, and rub in in now, stretch out your nipples, practice a little bit of hand expressing with your colostrum if you have some now..just hand them regularly, sounds full on, but soon they will be handled alot more than you can possibly do now!

Best of luck and wonderful news that you will be trying second time around!! It really is easy after a couple of weeks settling in..just perservere and it will be worth it!
