We four siblings have Joint enduring PoA for our mother who is in late stage dementia and is currently in hospital with pneumonia. We have massive problems with our sister who is one of the attorneys and we have been under investigation from the OPG twice because of her unfounded and untrue complaints about us. We truly believe that she has some kind of mental disorder. The thing that worries the three of us right now is that our sister is arguing with advice given by the hospital. The first thing is the DNR, which is in place but she won't agree to. We can understand that this is an upsetting document and our thoughts on this is that the medical teams will do what they think is right anyway, so that argument didn't bother us too much. The second issue, however is bothering us - our mother has pneumonia and poor swallow. The hospital told us that when they gave our sister advice on suitable food and drink for our mother she has argued with them, stating that there is nothing wrong with our mother. Our mother is usually in a nursing home, but often won't eat for carer's, so we all take turns in giving her her meals. Sadly I think it is because she trusts us. Our sister is wrong and needs to respect the advice given by the medical staff. What can we do to make sure the stubbornness of our sister is not allowed to impact on our mother's health?
