Hi Vaz
Do you tell your mum that your dad is dead, and if so does this distress her? If so, it might be best to use what is commonly referred to on this forum as love lies. For example, that he's just popped out to the shop and will be back soon, or he's gone away for a bit to help his cousin (or some other relative) who's had an operation. As for wanting to go home, it's most likely that your mum is thinking about her childhood home, rather than the one she's living in now - a place where she felt happy and safe and secure rather than this place where she feels confused and scared. Unfortunately this is what dementia does to those we love. My mum often doesn't recognise her home even though she was born there, but it doesn't look like the home she was in as a child, and the people she lived with are no longer there either. So again I would suggest using love lies - you're both on holiday at the moment and will be going home at the end of the week, or, if it's the evening, that it's too late to go home today, but you can go tomorrow. I'm sure others on the forum will be on to give more suggestions., but I hope these help.
