When a parent is dying and a sibling is having crazy behavior

[Anonymous]

We are going to lose our father in a few short months. One sibling (out of 4) has always been a bit crazy and has limited contact with siblings but regular contact with father. The three of us have been trying to speak with her about appropriate behavior with him. Limited hysterics in his presence. Stop removing items from the house. Whe she is there to take care of him she has to wake up before noon to actually take care of him, etc. She is directing most of her ire at one sibling including cutting her off of texts with medical updates, cancelled her as being authorized to speak to doctor and other very weird snarky type things.

Has anyone be in this position? I worry that as this goes on she is going to strike out more. I have spoken to her but she always has an excuse or the worst part is her going to our father to say she isn't welcome around his house. We actually need her help and our father loves her but we am unsure how to make this less confrontational and protect our father from her trying to break everyone apart.

Any ideas?

If she is that crazy, she shouldn't be part of the care taking team. Remove her from positions of power and responsibility. That is how you deal.

Nothing to advise on, only to say I'm sorry you are going through this (both the sibling part and parent dying part).
