They are happy to give him simple meals, but I doubt they would cook anything from scratch. They don't seem to know The microwave broke down, and he had to tell one of them how to heat soup on the hob. She had never used one before, believe it or not. That is why I bought yoghurt and fruit, as I thought this would be a simple and healthy breakfast for him. I also bought some cooked meat and bagged salad, but those things only last a day or two once opened, and even if they are not, they tend to go off unless used by the appropriate date, even if kept in the fridge.
I could even organise a once a week on line delivery for him. But I can only do so much, and frankly I think I have already done more than should be expected of me. The carers don't seem to know anything about diabetes. They originally bought full fat milk and white sliced bread for him as staples when he came home from hospital.
