How can I deal with a mother in law who denies there is anything wrong but is now becoming a danger to herself and her husband. She forgets what she is cooking, leaves the externall door unlocked and has no idea that her clothes have not been washed for weeks. Additionally she has sight problems, as does her husband Her husband is frail and we really have to consider a care home but how do I tell them??? I did get them to day care once which they said they enjoyed but refused to go again unless I went with them!!
