The trope that stepmothers are prone to loathe and mistreat their stepchildren can be found in fairy tales and folklore all over the world. So common are Evil Stepmothers that inverting that trope will make things interesting. Cue the Good Stepmother, a stepmother who ends up making the life of their stepchildren better. Far from plotting to get her stepchildren out of the way to secure the family fortune for herself, she instead acts as a mentor or protector to her stepchildren and shows genuine affection for them. Plots usually feature Good Stepmothers as supporting characters who help their fosterlings (the protagonists) succeed in life and "make their fortune". To fill this role, the Good Stepmother is exceptionally clever and resourceful. Often there is even something supernatural about her, making her somewhat similar to a Fairy Godmother. This tale type also likes to take elements of the well-known Wicked Stepmother stereotype and turn it on its head—for example, the Good Stepmother is quite frequently an actual witch; but one who uses her powers for the benefit of their stepchildren. The stepchildren do not have to be actual children. More typically they are teenagers or young adults. Because of that, the Good Stepmother is not always a Parental Substitute. If the stepmother has children of their own, they will get along well with the children of the first wife, and may even form a team. Good Stepmothers are also the norm in dom coms which feature a blended family. Often, there will be an episode dealing with how the stepchildren fear or expect their stepmother to be wicked, and are then proven wrong. Compare and contrast Happily Adopted, which involves an adoptive family, not just a stepmother.
- For some reason or other, this seems to be popular in Icelandic fairy tales:
- "The Horse Gullfaxi and the Sword Gunnfoder" takes a premise that is typical for Wicked Stepmother stories and completely subverts it: A widowed king marries a new wife who is actually a half-troll. Eventually, the new queen's full-troll sister lays a curse on the king's son, Sigurd, which he then succeeds to lift with the help and advice of his stepmother. In the end, Sigurd rescues his stepmother from being burned at the stake under false accusations of murdering her stepson.

- When her stepsons Erik and Agnar are killed by king Eystein Beli, Aslaug of The Saga Of Ragnar Lodbrok weeps a single tear of blood for them (which is a lot, as she never cries), and afterwards persuades her biological sons to avenge their stepbrothers.

She also promises that her magic will aid Erik whenever he calls her name, and helps him in outwitting King Gotar of Norway. When Gotar's assassins attack Erik in his bed, he calls out his stepmother's name, whereupon a shield happens to fall from the rafters, covering his body and saving his life.
- In the Old Icelandic Saga of Bosi and Herraud, the brothers Bosi and Smid are after their mother's death raised by their father's magically skilled concubine, Busla.
