Not having heard the story (though I'd love to!) I'd say either market the CD to grown-ups, and they can share the story with their kids if they choose, or else remove that story. The only other alternative I can think of would be to somehow redo it and change her profession, unless her profession is integral to the story somehow.

As a parent, I would have no problem sharing this story with my daughters, but as someone who teaches children's literature, and who has discovered in her research that Goodnight Moon is considered by many parents to be "disturbing" and "potentially traumatic" . . . let's just say any hint of sexuality in a story intended for children would be considered cause for a lawsuit and a lynching among many many parents. Sad, but true.
