Thank you Nisght Stalker and Mysticelt. I managed to grab 30 minutes of sleep. Stephen has urged me to consider sleeping aid but I do not wish to be dosed out if something should happen. My father has now been stable for 12 hours and counting (and I can tell you I count every minute). The silence is unbearable but as long as there is no phone call there has been no negative change.
Jackie and Josh are now at Stephen's parents. I must say I feel terrible since I made Jackie cry when she sat in my lap. I couldn't control myself and burst out into tears and she followed.

I don't think she understands more than "grandpa is very sick". I must say I envy her some.

OK I'm off to see if sleep comes easier this time with Stephen beside me. Thank you all!
