Clare, thanks for the suggestions. We have been talking about getting them assessed for a couple of months now (we have gone through the process with Nanna's sister and my MIL has done it with her mum, so we know the system a little). Pop agrees Nanna might need it, but flat out refuses to get himself assessed. I can so understand that they are reluctant. But it is really frustrating for us. They are so proud. He's the kind of person who can barely walk to the front door, but will still change his own tyre - and if it kills him.
We have been trying to convince him to stop drivung (he falls asleep mid-conversation sometimes) since he had a stroke last Christmas, but he insists that his doctor said he's fine to drive. If his doctor saw how many dings he gets on his car every week, he wouldn't say he's alright to drive. But this is a whole other issue.
If you ask me, it would be best if they both were in a home or at least had some in home care. But they don't want to do that and I actually understand them. It must be so hard to admit to yourself that this is not just a temporary situation, but that you are not going to get better. They are still of that mindset that Nanna is just sick, but the doctors will sort her out and then she'll be a spring chicken again...

Nanna has actually been prescribed some sort of nutrition shake. I don't know what it is, but it is apparently made for her exact situation.

Sorry for rambling on and on. It is actually so good to share, though. It really weighs on my mind a lot...
Thanks for listening.
