Itchy breasts?

KRT

Anyone else experiencing this?  I have noticed it quite a bit lately.  I am not sure if this could be thrush or just dry skin.  I noticed it on the outside of each breast.  More on the skin next to the areola and just on the edge of the areola.  No shooting pains, etc.  DS goes for his 4 month check up in a week so I can have them check his mouth but I don't see anything.  Thoughts?
