I would seem that by staying with the Father in Law for a week would be an execellent time to observe just what abilities are, such as can they handle actually taking their own bath or are they muddling through bathtime and it is so so, Do they remember what day it is or do they have to keep looking on a calander someone marks for them. If you ask them a question do they get irrate because they cant remember the answer? Such as "What did you have for lunch today?" and they get irritated and say leftovers, etc... because they don't remember what they had. (I have this client, she don't get to upset, but she'll say the first thing to come to her mind a food, any food, just to answer your question, even though you personally know you made roast. I let my client find the salt and pepper for me when I'm cooking, she will offer to find the cooking pot because she still knows where that is. and she puts the butter etc back in the fridge when I'm finished with it. It is really great, and she loves to be in the kitchen being productive. And she gets to be at home for the time being. I am only there 3 days a week, but I give the family a break during those days.
Well, hope everything turns out the way you want. Sherrvonne.
