My mother-in-law has advanced Alzheimers. My father-in-law has been taking care of her with help from a daytime caregiver. Now he is starting to slip, too, but he won't admit it and refuses to consider assisted living at all for them. He has already fallen twice. He is not taking care of her like she needs to be taken care of. He's not taking care of himself like he needs to be taken care of. The daytime caregiver is worthless - she just sits and watches TV with them and doesn't do anything, but he likes her and won't let us replace her with someone else. Not sure what to do at this point other than let time roll and deal with the aftermath. Suggestions?
