Ouch, sore nipples, I remember that well. I had Lanisoh but it never seemed to make a difference, it just made my boobs a fluff magnet. The only thing that worked for me was the milk squeezed out and left to dry. A friend of mine swears by those silverette things.
How lovely having a newborn, I almost envy you those sleepless nights (although DD has been waking me up at 3am lately, but it's not the same). I hope you're putting your feet up and getting lots of help.
