my husband is now - with great reluctance - in a care home, I don't go every day or rarely even two days together, I also vary the time of day, that way you are not expected, on any particular day or time. I was advised to do this by someone who works in a home and it means even the staff don't know just when you will be in, an hour is more than enough time I think as concentration is impossible to keep up from the patients point of view
