After having read your post I am firstly inquisitive to know how your aunts friend actually knows about your aunts ablutions? I would not dream of asking one of my friends if they had showered that day/week, whatever. And the staff should just be saying to her 'sorry, but I am not allowed to discuss residents personal lives with anyone but their close family and then walk away, making it very difficult for the friend to argue with them. Confidentiality should be part of their job! I remember when I was working in a residential home many moons ago, we had a lady in and her son was one of the local ministers. Like a lot of elderly folk, she thought that we encouraged them to get washed far too often and would often resist our efforts. So one evening as I was helping her get ready for bed and trying to encourage her to freshen herself up with a flannel and soap, she was having a bit if a grumble, so I said to her ' come on xxx, you no what they say, cleanliness is next to godliness '. She just took the flannel and glared at me lol. I didn't realise the relevance of what I had said to her until I thought about it later. But, a strip wash is as good as a shower for the older folk. We also had an elderly lady who had had a mastectomy without a reconstruction and she would only let the mature carers help her take a bath because she was too embarrassed to be seen naked by the younger caters, so we respected that and helped her retain her dignity. There are so many reasons folk might not want the daily showers/baths that we are used to, it never did us any harm when we were young so am sure it won't hurt them. As for the changing of clothes, try and remove them unobtrusively and then offer her a choice of this or that the next day. Older folk sometimes find being given an open choice about what to wear quite overpowering, but only having to choose between two outfits is much easier. Don't let your aunts friend get to you, she is maybe a bit jealous of the care your aunt is getting.
