Such a good and clever idea, Grahamstown. Much of what we have to do is reduce anxiety. I made a mistake yesterday and mentioned I could not find something, any loss causes anxiety so a very noisy search was made in all the unlikely places. Peace did not reign until it was found, a plant had been moved a little and it was behind that. This clingy behaviour is the same, I am lucky as our home is very compact to I can be heard, hearing aids willing, but I can hear unusual sounds too. Rather like when children are young, one tunes in. My secret weapon at the moment is the TV with headphones this means he is occupied and I can sit near often looking at Talking Point and shopping via the iPad.
