Ginny, How is the milk supply on that side? Has baby had a preference for the other side, or is this totally new? I do see babies who nurse on both sides for a while but one side preferentially, and when they finally run the milk supply on the less preferred side down, they abandon it altogether. If this is not the case, however, then I agree with the others: look for an undiagnosed ear infection, or have the mother's breast checked for that rare possibility of cancer. -Lisa ****************************************************************************** Lisa A.
