I have a Mother in law with Alzheimer's, she lives at home with father in law, I go into see them every morning as I live close, father in law is getting very tried and upset as she is getting up every morning at about 2.30am fully dressed wanting to get up (they sleep in separate rooms) he has back and leg problems and is unable to get about without sticks, I don't know what to do or say, he gets upset with her and then she gets upset that he keeps getting on to her. The doctor don't want to put her on sleeping pills as she goes to the toilet a lot and if she has sleeping pill she may start wetting the bed. I just don't know what to do, any advice would be helpful.
