Voice for people we care for

I understand that we are all about carers,
However, since my wife lost her speech due to stroke over six years ago, I have been trying to find ways to give voice to her, specially for her well being, I am unable to find any site which would raise voice for them.

I wonder if we the carer can do so for the people we care for?,
since we have all the information about them, by being with them, specially those who are unable to voice their needs?
Can carer help, and campaign for them ?

I would very much like thoughts and comments about my suggestion

Does your wife still understand things well?
Do you have Power of Attorney for her?

Hello and welcome!

Yes I advocate for my caree as much as possible. But since he can talk, I gently ask him to politely speak up for himself instead.
