sorry, forgot to add some other tips which I found useful in preveting cross-infection:
husband and put away hand towels and washed hands more often than before and dried off with paper towels instead
don't use anti-bacterial soap or washing up liquid - these kill the GOOD bacteria
wash all clothing in at least 60 degree hot water - thrush is only killed at 50 degree temps. and above
best way to kill thrush in expressing equipment and baby feeding stuff, etc, is to boil in a big pan for at least 20 mins. (steam sterilising does not kill thrush) or use Milton sterilising solutuion or tablets, see below
I didn't know about Milton disinfecting stuff, but have since realised by reading the small print on their products, that it kills the thrush bacteria, so use it for kitchen surfaces, baby high chair, etc.
A good natural remedy for nipples, is a very light vinagr solution (one part vinagar to 10 parts water) of course only use if nipples not cracked or really sore !! I used to dab some on straight after each feed and then put canestan cream on as well
ps - someone mentioned canestan - I read somewhere info, by a leading bf doctor that it can be left on nipples as only minute amounts get absorbed into the baby - obviously don't put on just before a feed - but if it has been rubbed in well at 30 mins. before a feed, or even better, AFTER each feed, no need to wash off
