Well, it's been a week or so now and I'm pleased to say my nan has stabalised. What has happened is that a decision (by her) has been made that she should go into a home. You might think that this is not a good thing, but on reflection it's a wonderful thing.
She had a day visit yesterday to see if she would like it, and when my mum went to pick her up, she was sitting chatting to another resident who absolutly loves it there. She can move in on monday. Bless her, she is a wonderful person, my nan and I am so glad she is happy again!!
