My sister and myself have helped our parents over the past 10 years so they were able to live at home for as long as possible. Earlier this year dad has went into care with mum who has dementia. Our estranged sister came back into the picture then and had him change Enduring Power of Attorney and health guardianship from us over to her as she lives closer. My sister and I have an 8 hour round trip to visit our parents, we visit monthly now that they are in care. However, our sister isn't keeping us informed of their health, even though we always emailed and let her know before. Mum is palliative now and my sister and I talked to dad that we would like to sit overnight with mum. When I asked a staff member if we could be rung also and kept informed she said only the person who is listed as "next of kin" I explained we don't think we will be notified by our sister in the case of our parent's health or end of life. Isn't it ok to have more than one family member to be notified in cases like this? Have others had this experience?
In general, facilities can only manage notifications to one person, and that is the one who holds POA, or is the person designated to receive news on behalf of the family.
Would dad change POA back to one of you?
Since your Dad is in the same facility, would it be possible to talk to him to see how your Mom is doing?
