Reading Thumbelina to my four-year-old, and realizing that she was basically... trafficked? Kidnapped from a loving home by a mother toad to marry her ugly son; she escapes but then is homeless, eventually taken in by a kindly field mouse. But then the field mouse eventually decides to force her to marry a mole who wants her to live underground, before finally escaping that and finding people of her own kind who respect her decisions. Makes you wonder for how many children that was more an allegory than a fairly tale, and how many didn't manage all their escapes.
