She is starting to turn away all the foods and drinks she has liked before. She is spitting into a napkin a lot. She chokes, she can't walk anymore. She is up and down in her sleep pattern. 2 nights ago she was up every hour...the last two days she has been sleeping all the time. Last night she slept almost 14 hours.
Your mother seems to be exhibiting end-of-life symptoms, but not necessarily the very final symptoms. No one can say for certainty when someone else's life will end. But hospice is very experienced at interpreting signs and I think your best bet is to talk to the hospice nurse, in detail.
