Mom has AML

My mother was diagnosed with AML. She had chemo and had to have another chemo but this did not work either. She is now home with hospice care.  I spoke with a doctor while she was on her 2nd round of chemo and asked him to tell me how much time she has....he told me she would not last past Thanksgiving.  My mother now is extremely weak. Has inflamed knees, cannot walk because of the pain in her joints, is incontinent because she cannot move fast enough to get to the bathroom.  She has extreme pain in her throat and was diagnosed to have thrush. I understand that thrush can be very dangerous as it may cause sores in the mouth that eventually lead to the other organs leading to potential bleeding. Does anyone have any information on this???
