Your post reminds me that I need to join up with the local Carers organisation.

And what you describe worries me - I've got my elderly relative, aflicted with dementia, watching a movie. #MyHouseInUmbria. It's late and I've got minor skin surgery tomorrow. So I've gone to bed.

But what happens in the future if they will not sleep and can't be left alone?

This #NuclearFamily stuff looks badly designed for the young and the old and their care-givers.
