at the end of the story, do you think phoenix's grandson is alive?

I believe the grandson is still alive, but I could be wrong. 

Phoenix spoke unasked now. "No, missy, he not dead, he just the same. Every little while his throat begin to close up again, and he not able to swallow. He not get his breath. He not able to help himself. So the time come around, and I go on another trip for the soothing medicine."

"This is what come to me to do," she said. "I going to the store and buy my child a little windmill they sells, made out of paper. He going to find it hard to believe there such a thing in the world. I'll march myself back where he waiting, holding it straight up in this hand."
