tingling could be thrush. ive never had it put there is a lot of info here on it.
sometimes my nipples tingle after my lo sucks for a long time though so it may be nothing. check out the descriptions of thrush and see.
imo, i would lay off pumping if you can, it is an added stress. If you are pumping to give bottles I'm not sure why. Can you explain? I am confused as to why you are giving bottles
sore nipples would indicate to me a latch that needs some attention.
and how many diapers? not sure if I missed that too
if you are giving formula more your milk is decreasing, that may be the cause of the fussing at the breast. Again, please check out the link from before, I really think it will help.
