Wanting to go home
Sandra,
The phase your father appears to be entering or is at is one we had to deal with over three years ago with my mother. The good thing is once this phase passes, and it will, (trying to escape) life gets easier.
When my mother first came to live with us she entered this phase of wanting to return home (to her mother's house she lived in as a little girl, where apparently her mother was waiting) Nothing would dissaude her that it was not there any longer. Althogh we were half way round the world to her she was convinced it was just down the road.
Our first attempt at a solution was to let her wander outside. Our grounds are large (approximately 10 acres) and are reasonably secure. She would go out repeatedly searching for a way to escape with a carrier bag hat and shoes under her arm up to 10-14 times in any day. The cycle would repeat itself after five minutes of returning. At the end of the day she would be totally and utterly exhausted but if not prevented she would have gone on until she dropped. It made no difference. It is 34 deg C in the shade here.
One day she escaped by crawling under the fence through some very nasty cactus and we had to search for her for some hours.
After this event we decided our strategy was not working and we decided to use confinement to the house and take her out for walks in the garden only when accompanied.
This phase was accompanied by all sorts of tantrums and use of emotional displays including tears that could be turned on or off as required, sometimes quite convincing; what an actress. It was necessary for us to be totally resolved to overcome this problem.
Wandering and trying to escape would even occur in the middle of the night. She failed to determine the difference between night and day. Our solution to that was to install a large 'baby gate' (only used at night) to confine her to one end of the house (bedroom and bathroom). We had to do this as she would wander round the house at all hours and urinate over the entire house, over all the furniture and floor. By doing this at least it was confined to her bedroom and hallway. We never did find out how she managed this without getting her pyjamas wet. She insisted this was a normal thing to do if challenged.
We ended up removing all clothes and items from her bedroom as she would constantly go through them. It was initially thought having personal items and photos would be comforting but in fact they did nothing and in my opinion made matters more difficult.
In our case my mother did not make a sound at night. What the solution might be if your father becomes vocal at all hours will need consideration.
As might be expected there was severe resistance to the measures we employed but being resolved (as resolved as she was) we overcame the problem.
Be advised they (the patient) can be very determined and my mother used to swear at me in no uncertain terms and called me many things including a jailer and said she was being treated like an animal etc., I did not give in and insisted whatever she did it would make no difference. I ignored all protestations.
Now the phase, which lasted in my mother's case for many months, has passed and in hindsight she accepted the gate quite quickly and now feels secure with it shut as she often shuts it herself.
Undoubtedly this is going to be a very difficult time for you as your father, being a male may well put up very strong resistance. It is necessary to succeed in this for their own safety. When my mother was normal she was a very passive personality.
Personally i have found it necessary to establish routines. This will help enourmously as time goes by inlcuding the washing problem. If you have a shower, preferably a walk in shower. I believe grants are available for these. Place a plastic garden chair in it and go from there. It is my view it is very important to get over this particular difficulty as soon as possible without drama. If you have a hand hose and shower head (if you have not then fit one) once seated just shower his legs and if he will let you his lower body. If it is a comfortable experience resistance is less likely. Make sure the bathroom is on the hot side. As the procedure is established it will be possible to graduate to showering his entire person including washing his hair.
The procedure I adopt in the shower is to soap the sponge and tell her which bit to rub i.e., body, under arms, legs and feet etc.,
When it comes to drying it is not such a big issue and does not need to be what you may consider thorough. Sit him down on his bed and hand him his clothes in order, one at a time. There will come a time when he may not be able to dress himself but in my opinion it is important to get them to do as much for themselves (assisted) as possible for as long as possible.
My mother would be quite happy if i did everything for her but I make a point of not doing it although often it would be easier.
I hope some of this may be helpful.
