That is very helpful, thank you. Dad keeps hurting his feet at night,I can’t see anything he could step on, but possibly his is walking into door frames . Certainly, he is slowly losing his past, living almost entirely in the moment. He is pretty content as a consequence, which is a blessing. Luckily he lives a short walk away, so I can keep a close eye on him. I hope it will be possible to give him his wish to stay in his own home, but that will depend on how ill he gets. It feels very odd and somehow wrong, to be considering his future knowing that if he becomes much sicker, his wishes will have to be ignored in order to keep him safe.
