In a fanfiction, it might start with Draco having a change of heart after the war. He sees Hermione's intelligence and kindness in a new light. They start a secret relationship. When the baby comes along, they struggle to keep it a secret. The story could then focus on how they navigate the challenges of raising a child while dealing with the prejudices of the wizarding society, especially those who still hold grudges from the war.
One possible plot could be that they are forced to work together on a post - war project in the wizarding world. At first, they still have their old grudges but as they spend more time together, they start to see each other in a new light. Eventually, they fall in love and have a baby. Their baby could then be a symbol of a new era of unity between the former rival houses in Hogwarts.
In the wizarding world, the reactions from friends and extended family would be mixed. Some pure - blood families might look down on the union and the baby at first. However, those who know Draco and Hermione well, like their Hogwarts friends, would be happy for them. Harry and Ron might be a bit skeptical at first but would soon grow to love the baby and protect it as if it were their own family.
They would become more united. Before the baby, they might have had a tenuous relationship, but having a child would force them to rely on each other more. They would have to communicate better to make decisions about the baby's upbringing.
Draco might be more protective in a traditional pure - blood way. He'd want to shield the baby from any threats to their family name. Hermione, on the other hand, would focus on teaching the baby about equality and the importance of knowledge.
Well, she might have a bit of a mischievous side too. Draco had his moments of causing trouble in his school days, and Hermione was not always a perfect rule - follower either. Their daughter could be a bit of a rebel, but in a good way. For instance, she might break some minor school rules to stand up for what she believes in. She could also be very charming, able to make friends easily despite her parents' complex pasts.
One possible plot could be that in a post - war world where things are turned upside down, Hermione discovers baby Draco alone and abandoned. She decides to take him in out of her sense of justice and kindness. She might struggle at first, trying to understand his needs as a baby Malfoy, but gradually, as she takes care of him, she starts to see the potential for change in him. Draco, as he grows up under Hermione's care, could start to develop different values than what he was taught in his pure - blood family.
One idea could be that Draco and Hermione's baby has unique magical abilities that draw the attention of both the wizarding world's good and bad elements. The baby might be able to communicate with magical creatures in an extraordinary way, leading to adventures where they have to protect the baby from those who want to use its power for evil.
Perhaps in this fanfiction, the wizarding world is facing a new threat that requires all houses to come together. Hermione and Draco are chosen for a special mission, and during this time, Draco's baby is left in Hermione's care. She breastfeeds the baby as it's the most natural way to nourish it. As she does so, she discovers new things about Draco's past and family that make her see him in a different light, and this changes the whole dynamic between them.
The fanfiction could be about how their relationship evolved to having a baby. Maybe it started as an unexpected friendship that grew into love over time. They would have to deal with the differences in their personalities. Fred being more carefree and Hermione being more studious. But their love for each other and the new baby would bring them closer together, and they'd create a unique family environment in the wizarding world.
One possible story could be that their baby becomes a symbol of unity between the former Slytherin and Gryffindor rivalries. The baby might inherit Draco's cunning and Hermione's intelligence, and grow up to be a great wizard or witch who bridges the gap between different Hogwarts houses.
