Some good things here. Name tags you'll have done already, but you can get some nice Copperplated fonts from the school outfitters to make it seem more individual. Don't bother so much with nice woollen clothes because I'm not sure you should have them there - they just get put in the wash first time round even if not soiled and then shrink. If you do have wool garments there, name them and hide them away in the room, taking them out for a nippy day out, only making sure to take them off your parent and re-hide them when you leave. Care homes are not cold.
Label things like the lovely counterpain - they can go missing in the first week, in fact any thieves around and they hit in the first week it seems.
Get a spy camera for the room, but don't install it. You can go to spycameracctv.com as I did. Get a pinhole one with night vision. Bad things tend to happen at night.
Figure out how the spy camera works at home, have a bit of fun with it. You need a micro card and a computer to download the app. Their customer helpline is excellent.
Why get one only to not install it? Well, if you have suspicions here's the thing: you needed that spy camera yesterday. It's later than you think and like another person's receding hairline, if you've just noticed it chances are it's been going on for longer than you know. You simply do not have time to research spy cameras on Amazon, and they are never it seems sold in any shops at all. You don't have time to read the poor reviews and order it in and then try to figure out how it works. This can take all of two weeks by which time it may well be too late.
It is also surprisingly hard to hide a pinhole spy camera. In a box of tissues? Not really, it can get moved by the cleaner, or dislodged. In a box of matches? No - because why do you need matches in a care home? You need to place it in an immovable object in which you can make a small hole. Not easy. A spy camera clock is all very well but if they know the type, it can be recognised, plus many parents obv will not be reading a clock if they have extreme dementia.
So get one but don't install it yet. Why? Because in doing so you cross a line - you admit you don't trust the staff. It's stressful. You then feel obliged to check the footage every day or so. For what may be years. it wears you down. There's every chance the staff will find it and think ill of you, when it may all be unnecessary. The longer you have it installed, the more likely this may happen. Some may cover the lens when they are with your parent. That happened to us.
I'll point out however that spy cameras do not really recall neglect in the form of dehyration. You can't exactly record nothing happening.
If the camera is found, you will be seen as a potential whistleblower. The care home managers won't like it, and may call in Social Services to quiz you on it - that happened at my parent's last care home in the Royal Borough of Kingston. If you did not know to get LPA in Health and Welfare they may spin you the line that you need their permission to install the camera - probably rubbish but Social Services do as they please.
And that's the other crucial bit of advice already given on this thread. Get LPA in Health and Welfare while you can, if you still can. Without it, you will not even be allowed to see your parent's medical notes, but any Tom, Dick and Mieka at the care home can see them. They can also use the notes to bitch about you at leisure to 'tip off' other staff about you, it's a sort of sewing circle thing where they can get their revenge - you sort of dimly become aware that something is up, but only find out when your parent has died. Because the State makes a big thing of keeping your parent's medical file from you while they are alive. They didn't know to get LPA so screw them, the thinking goes.
