Query: Confusing!

The first time I read this book, I could not figure out the relationship of the characters. One generation was totally missing. There is the elderly mother, her daughter, and the boy--who is not the son! After rereading it, I inferred that the daughter had a child who was the parent of the boy, but is never mentioned. Also, I would never have known the elderly person had alzheimers if I had not read the book jacket since it is not stated in the story. Can anyone who has such vivid memories of her life have a serious case of alzheimers? Because I was confused with this story, I imagine children will be as well.
