Okay, I have had this exact problem, among others, and it WAS thrush. OUCHIE!!!!!
I elected to have his Ped. prescribe the antibiotic and just purchased the Lotrimin for my nipples and his diaper area. Even though he, also, did not have all the signs my first ds had when he had thrush, I still had to do the antibiotic in his mouth and cheeks to rid it away from us forever!!!!
And from time to time, my nipples seem to crack a bit, but absolutely nothing like it did when we had that darn thrush!!!
T My other problems with this bf "session" with this babe, is my supply. I have been taking fenugreek since about his two wk. mark, and he is now fourteen wks., unfortunately, I have been having to supplement with nasty formula. We still have our nighttime nursing, and in the mornings, and only a handful during the day. Maybe I should be posting elsewhere, but any of you here, reading this on this one, could suggest anything!(?)!!?
This is the longest bf "session", and it means more than I can explain, to continue as long as possible!!!
