Similarly here.

We worked on de-sensitizing. So for some of the stories with very mild bully or teasing of another child (one or two B. Cleary books come to mind, way below lexile level, but useful), we would talk about why the author wrote it that way.

And for other stories/movies that we, the parents, know the ending to, we would tell the child how the story ends and that it all works out.

But yes, we delayed Charlotte's web for an extra year and decided to tell child the ending before we read it.

Best wishes!
