DD2 is 10 days old and BF'ing. Have had a v. engorged boob with possible mastitis (doc not sure) and last night was draining it after a feed by expressing with my elecric pump and when i went to empty it I saw that I had produced something that I can only describe as semi-solid milk whey - DH's description was 'boob cheese' which turns my stomach a bit but it probably gives a better description.
What is this stuff?
DD still seems to be able to feed and I noticed that she's managed to extract some of this stuff as well when she's been feeding.
