Well, in this fanfiction, perhaps Hermione adopts a baby who has some sort of special magical ability. Maybe the baby is an orphan from a tragic event in the wizarding world. Hermione, with her kind heart and strong sense of justice, decides to take the baby in and raise it as her own. She would then face challenges like protecting the baby from dark forces who might want to use the baby's power for evil.
The Ministry of Magic itself could be an antagonist. If they don't approve of Hermione's adoption due to her age or some bureaucratic reasons, they could try to take the baby away. They might think she's not fit to raise a child, which would create a lot of conflict in the story.
Well, in this fanfiction, it might start with Snape finding Hermione as a baby in a dangerous place like the Forbidden Forest. He adopts her because he sees her potential even as a baby. As she grows, he teaches her magic in his own strict way, but also forms a deep bond with her. This could lead to some interesting interactions with other Hogwarts faculty who are surprised by Snape's new role as a father figure.
She would face the challenge of dealing with Tom's own nature. Even as a baby, he might have some of the traits that later led to his dark side. Hermione would have to find ways to nurture his good side and suppress the bad. Also, she has her own life and studies. Balancing taking care of a baby and her own development would be difficult.
Snape would become more nurturing. He's used to being cold and distant, but with a baby to care for, he'd have to soften. For example, he'd learn to comfort Hermione when she cries.
In a fanfiction about Kagome adopting a baby, the story might focus on how she adjusts her life. She would have to deal with the reactions of her friends, like Inuyasha who might be initially confused or even a bit jealous of the attention the baby gets. Kagome, being the kind - hearted person she is, would make sure the baby is well - cared - for, perhaps using her knowledge from her own time to provide better healthcare and education for the child.
A fanfiction titled 'Hermione's Refuge' has Remus adopting an abused Hermione. This story is unique as it not only focuses on Hermione's recovery but also on how Remus has to face the wizarding community's reactions.

In such a fanfiction, Sirius might have to face various challenges while adopting Hermione. For example, there could be opposition from some parts of the wizarding community who might question his motives or his ability to take care of her. However, Sirius, with his strong will and love for Hermione, overcomes these obstacles. He might also help Hermione develop her magic skills further and give her the confidence she lacks due to the abuse she has endured.
One great fanfiction with this concept is 'A New Beginning'. In it, Narcissa discovers Hermione's situation and decides to take her in. It beautifully shows Hermione's adjustment to living with the Malfoys and how Narcissa protects her from further harm. It also delves into the complex relationships within the wizarding world and how Hermione's presence changes things for the better in the Malfoy household.
It would change the future of the wizarding world a great deal. Hermione is a smart and kind - hearted witch. With her as Tom's mother figure, she would likely encourage his academic pursuits in a positive way. He might grow up to be a great wizard who uses his powers for good instead of evil, thus changing the whole power dynamic in the wizarding world.
