LO is 17 days old. Recently I have been experiencing itching in whichever breast I am feeding her from. It is not the nipple that is itching-- it is the entire breast. The itching seems like it is under the surface and there is no visible cause (such as rash, stretch marks, etc).

Background: I have been breastfeeding, pumping, and also supplementing with formula (due to excessive weight-loss in her first 24 hours). I feed her from both breasts every 2 hours during the day. At night she gets a bottle and I pump. I also pump a few times during the day. I do not feel the itching sensation when pumping.

I tried Dr. Google and everything keeps suggesting mastitis, but I don't have any other symptoms of mastitis (pain, swollen breasts, fever, etc).

Has anybody else had this or anything like this??
