In some fanfictions, the idea of Hermione and Severus having a baby might be conceptualized as a way to explore an unexpected relationship. It could be a plot device to show the power of love and connection that transcends the typical boundaries of their relationship in the original series. Maybe it's a result of a magical accident or a deep, hidden love that blossoms over time.
One way could be through a time - travel or alternate - reality plot. Maybe Hermione discovers a way to go back in time and change Severus' fate. She sees his potential for good and they form a deep friendship that gradually develops into a relationship where they consider having a child together. This would focus on their mutual understanding and respect for each other's intelligence and abilities.
