Pink,
Prevention is one-so you can start applying the cream(thinly, not too much, that's not good too) at the first sign of soreness. Using your breastmilk is also helpful... remember to try to 'air' them so if you can be braless for a while after you feed, that can help too... if all else fail, you will need to feed baby on the 'good side' and give the other one some time to heal...usually it heals quite fast if you dont let it worsen...
I agree with gerry, bf can be a nice experience bonding with baby, so just need to overcome the inital 'teething problems' during the 1st month of breastfeeding... sometimes, mummies give up prematurely because they are unaware and discouraged cos they didnt expect the 'problems' early on and did not seek early 'intervention'... bf is a personnal decision for the mummy, just wanted to share cos I've also had my fair share of problem when I tried to bf, i took it one day at a time and managed to bf my 1st baby for 7 mths and 8mths for #2. ;-)
