MIL is still hanging in there, though it still doesn't look good. We took the kids to see her Sunday night - to say their goodbyes if necessary. There were plenty of tears.
MIL, of course, does not look herself.. with all the fluid they are pumping in. DH, his uncle(her brother) and DH's brother have decided to maintain the levels she is at, that nothing more would be increased to keep her going, as they don't believe that is what she'd want.
However, she is still hanging in there, the next thing would be to do dialysis, which she wouldn't want, so I don't know what will happen next.
Thanks for all your kind thoughts!
