The person doing daily care needs direct help more than admiration from a distance.

Daily care is made of small repeating tasks that continue whether or not anyone notices them. Praise costs the giver nothing and removes nothing from the load. Being called remarkable can even isolate a person, because asking for help then looks like failing the description. What actually changes a week is an hour of it taken off their hands.

Offer one specific thing with a time attached: Thursday evening, the shopping, two hours so they can sleep. Say what you will do rather than asking what they need, since answering that question is itself more work for them.
