One possible cause for the scab with clear yellow fluid in your question #3 is impetigo. Since this mom has a 4+ year old, maybe the child has a case or the mom has a skin condition such as dermatitis which got infected. I'm not sure how impetigo would explain a more prominent nipple, unless there's some swelling as well. She should probably see a physician for a diagnosis. Hope this helps. Alicia. [log in to unmask]
