Firstly, I love bf and am committed to continuing for the forseeable future! It'd take more than horrible, spotty skin to make me stop - but that's what I have. I've had acne since I was about 6 m pregnant, and DS is now 13m. I think it's acne because the same spots get inflamed again and again, unlike the pre-period spots I used to get, which came up anywhere. My chin's particularly bad. A friend who's bf for the same length of time has the same problem.
Is it related to the hormones that keep the milk coming? Has anyone successfully treated this while continuing to breastfeed? Am about to jump on the Oil Cleansing Method (just as soon as me castor oil arrives!) so perhaps that'll help.
