oooo this is one for mears/tiktok et al on the BF threads. I'm at your GP. I'd report her for bein unsupportive. You'd kind of expect more from a GP wouldn't you?
Basically you should get fluconazole tablets for up to 10 days, daktarin gel for your boobs and nystatin suspension for LO (although someone posted on my thread the other day that the LO should get Daktarin as well, as the nystatin (that's the cherry stuff) takes longer to work.
My HV gave me This advice from the Breastfeeding Network.
Are you still in touch with the team at QM? the BF counsellors there should be aware of the latest advice and could perhaps prescribe the right doses. They could also check your latch to make sure that isn't the cause.
