Hello
@Mumbies and welcome to DTP
This is a perennial problem - there are probably thousands of people up and down the country asking to go home when they are sat in their own homes and it is something that you can never satisfy. Even if you took her back to her childhood home, she would still be asking to "go home", because it is actually a state of mind, rather than an actual place. What they are asking for is to escape the confusion and go back to a time before dementia. Often this is a childhood home and also contains long dead relatives, but sometimes its another place where they have been happy, or sometimes a fantasy place. All of them are equally unobtainable.
Often they switch between recognising their homes and not. Telling her that she is in her home when she doeant recognise it is likely to distress her, because at that time, in her mind, she is certain that it isnt and you wont be able to persuade her, but if you agree that it is isnt her home, she will probably demand that you take her home RIGHT THEN! Try coming up with a "reason" why she is there that will satisfy her. Perhaps you are looking after a friends house while they are away; perhaps there is a problem with the heating in her own home and so she is staying with you while it is fixed. Try sying that you will take her home tomorrow, but its too cold/dark/busy on the roads/car needs fixing to do it now. You could even try walking or driving her round the block and when you get back saying "ah, here we are - home!". Some days one thing will work and another day it wont. Its not easy.
