Saw your other post - you are having a rough trot!
Personally, I found my nipples to be extremely tender for the first 6-7 weeks with Natalie and 4-5 weeks with Phoebe. There was no thrush, but as baby and myself got used to the whole breastfeeding gig I found my nipples took a little bit of a battering.
Glad to hear the daktarin is working well for you - that's positive. But I personally think a bit of tenderness in the first few weeks is pretty normal...
