Crissie I have an article, I think I mentioned it to you before, and it is about the 10 Signs that the End is near. If you email me and request it (just click on my name to the left and my e mail will appear) I will send it right over to you also with some advise. I just don’t like to ‘open’ post it.
I am so sorry that it has gotten to this for you and your dad. Being in hospice lands you with the most caring hands at this point. I have worked with a lot of hospice patients over the years and every one is different (I know you get tired of hearing that). As long as he is keeping some fluids (even just a little) he can go some time. If he cannot keep fluids down then the time may be even shorter. If Lainy has not already sent it to you then have her send you her list of things to look for. It will help.
One thing I will say is that even if it seems that your dad is not awake and not able to hear you, keep talking to him. The understanding is that hearing stays even when someone is in a coma. Talk to him as much as you can. I have had people read newspapers, books or magazines. Hearing a loved ones voice can help ease anxiety.
So sorry it has gotten to this.
