Lady Aisha Siddiqa (may Allah be pleased with her) narrates: While I was in the state of menstruation, I would place a vessel to my mouth, then I would pass it to the Prophet Muhammad (peace be upon him), and he would place his blessed mouth at the same spot where I had placed my mouth. While I was in the state of menstruation, I would take a bone (with meat on it), eat from it, then pass it to the Prophet Muhammad (peace be upon him), and he would place his mouth at the same spot where I had placed my mouth.
