One possible reason could be to reflect historical parenting methods. In the past, spanking was more commonly used as a form of discipline, and stories might include it to show how things were. For example, in some period novels, such a scene might be included to give an accurate portrayal of the era's family dynamics.
It might be used to create a sense of conflict or drama in the story. The act of spanking can be a very intense moment that can drive the plot forward. For instance, if a girl in a story does something that goes against the family's values, the mother spanking her can be a turning point that leads to the girl's self - reflection and growth. However, this should be done carefully as it can also be a controversial element.
