Hospice at home?

I did not quite understand your post regarding where your father is located right now. Is he in a hospital or hospice facility now? If he is not at home presently and you are questioning whether or not to return him home under hospice care or leave him away from home, I would think you have to evaluate how your mother is handling his current absence. If she has accepted his absence and her condition is progressing, you might consider not bringing him home because it will add significantly to the demands for care and cause you to change the routine established for your mother. Visiting him at whatever facility where he is provided care might be a better and more manageable state for your mother and all providing care. Your mothers condition can change course or the pace of the disease at any time without notice so you may not want to risk having them both at home requiring significant care at the same time and your mother trying possibly to intervene or "help". Good luck with a very difficult decision. Balancing love and practicality in this disease can be hard.
