Not been around for a while as things with Mum were quite stable but over the past few months she has been getting worse not knowing if it is night or day as a consequence she has not been going upstairs to bed ( she can still go up and does several times a day in her wanderings) and spends the night in her chair Is this common? Is she safer downstairs at night if she wakes up? Mum seems happy about staying down but when I tell other family members they say she should go to bed but they do not have to sort it every thing is left to me
