I have taken my mother for a drive. She doesn't live with me but I had to drive her to a couple of hospital appointments that she was advised could not be postponed so I just drove the 'long way round ' to give her a change of scenery. It really cheered her up. It's your decision east12 but I cant see the harm in taking your Mum out for a drive, especially if you do live with her.
My Mother who suffers from Dementia is getting more and more depressed each day during this lockdown, she used to look forward to going to the day centre twice a week but now has not been out of the house for nearly two months, I would like to take her out for a drive if possible as I still take care of her.
