I will also add to my previous comment:
Communication between my out-of-state brother and I was so key. Mutual respect a necessity. He had health issues himself, precluding travel. But I would keep him apprised of dad’s major health issues, doctor opinions, scan results, etc. Dad knew that I kept my brother up on the major things. I invited him to FaceTime big appointments, which he declined to do for a variety of reasonable reasons. But because he was removed from the moment to moment daily of life, he offered a place to dad where he could be “his old self”. Since my brother was not physically here to see the indignities of age decline, I know my dad felt like he could relate to him (and my brother could still “see” him) as his younger self. I know my brother would ask him how to do things that he (my brother) probably already knew how to take care of. But that gave my dad a sense of purpose and usefulness.

But when dad wanted a rolater to use instead of his walker, my brother respectfully asked why I was opposed to it, privately (and with the knowledge that he wasn’t here to see everything). He understood when I explained that it would be a danger for dad given his current mobility challenges (and this confirmed by the PT—not just me being too protective/controlling). Things like that come up and if everyone can come from a place of wanting the best for the care recipient, and there is mutual respect, everyone can be so helpful even if they play different roles in the care…..
