My lo is 5 mo old and I am an exclusive pumper by day and a breastfeeder by night (when he is too drowsy to realize that he is bf). The last four days or so I have noticed a thick white/yellow crusting on my nipples. They are not painful in any way. My lo does not have thrush, however since I have noticed this crusting he refuses to bf in the middle of the night. Is this yeast? Are they blisters? I would think if they were blisters they would hurt. ???? I am curious to see if anyone else has had this and what they have done for it. I am also anxious for my lo to bf in the middle of the night again. Thank you in advance.
