Christine, is this mother of local nationality? If she is, then I wonder whether her yellow looking nipples are just blanching due to nipple trauma or Reynaulds, the natural colour of her skin is 'colouring' her nipples a yellowish shade? I observed a caucasian mother with this problem and her nipples on blanching had a ghostly whitish/greenish/bluish tinge, devoid of all signs of blood flowing through the flesh. It was the same colour one observes in the face when one is about to faint or vomit. Her nipples then flushed bright red, we nicknamed them Traffic Light Nipples. She felt the excrutiating pain when the spasm released and the blood flooded back into the nipple. Once we got the positioning sorted out it disappeared. Comments anyone else on Christine's observations? Helen Woodman, Storrington, West Sussex UK.
