Re: UGH! Thrush, for 5 months?
Is your daughter also being treated with Diflucan? it does NO GOOD for you to take it if she is not. You both need prescriptions for it, at the right doses, and may need to take it for several weeks - longer than symptoms persist - in order to fully clear it up.
Also do you have Grapefruit Seed Extract that you are using in EVERY load of laundry, as well as swabbing your nipples and your DD's mouth before and after every feeding? That will make a big difference as well (you can buy it online and dilute it 10-20 drops per 1 oz of water i believe and apply with cotton swabs).
DS - 6 & DD 3.5
