If she can't eat, keep her hydrated.

A relative of mine survived colon cancer when they were not expected to and was gaining weight during a time when most cancer patients are losing weight. If he couldn't eat lunch, he got a homemade milkshake with milk, ice cream and fresh fruit. If he was too sick for that, ice, frozen juice and frozen fruit got blended together.

Some days, such meal substitutes accounted for both lunch and dinner.

Good wishes. Sorry you and yours are going through this.
