One possibility is that the story could focus on how they balance their magical duties with raising their daughter. For example, they might have to deal with threats from the remaining dark forces while also teaching their girl basic spells and the importance of kindness in the wizarding world.
One possible storyline could be that in the fanfiction, Harry and Hermione discover their feelings for each other later in life, after all their adventures. They get married and decide to start a family. Their baby could inherit some of their magical talents, like Harry's ability to speak Parseltongue and Hermione's exceptional academic skills in magic. The story could then focus on how they raise the child in a world that is still recovering from the dark times of Voldemort.
Some of the more traditional pure - blood families might oppose it. They have strict ideas about family and bloodlines, and Harry and Hermione's situation doesn't fit into their narrow view. For example, the Malfoys might initially be against it, seeing it as a break from the 'normal' wizarding family structure.
Well, their friends' reactions would be a mix of surprise and joy. Some, like George, might make jokes about how Harry and Hermione finally got together. But deep down, he would be happy for them. The other Hogwarts professors, like McGonagall, would be proud to see two of their best students starting a family. She might even offer to babysit on occasion. The friends would also come together to throw a big celebration for the baby's birth, and it would be a time for the wizarding community to celebrate the new addition and look forward to a bright future with this new generation.
Their relationship would become more intense and committed. Having a baby together means they are now a family unit. They would have to rely on each other more than ever. There would be a deeper level of trust and understanding between them. They would also have to communicate better to make decisions about the baby's upbringing.
It could start with Hermione realizing she is pregnant. Maybe she's in the middle of researching some ancient magic in the library at Hogwarts when she suddenly feels unwell and realizes what's going on. She then tells Harry, and they both are filled with a mix of joy and fear.
Yes, there are likely fanfictions where Harry Potter calls Hermione 'baby'. Fanfiction writers often explore different relationships and character interactions in the Harry Potter universe, and this kind of endearing or unexpected use of language can be a part of their creative interpretations.
One idea could be that their baby girl has a unique magical ability that combines Draco's pure - blood magic heritage with Hermione's brilliant intellect. For example, she might be able to instantly understand and translate ancient spells. Another idea is that she grows up in a world where the old rivalries between Slytherin and Gryffindor are starting to fade, and she becomes a symbol of unity between the two houses. She could be friends with children from all different houses and use her influence to promote harmony at Hogwarts.
The baby could be a really interesting mix. It might have Hermione's bushy hair and Legolas' pointed ears. And perhaps inherit Hermione's intelligence and love for books as well as Legolas' amazing archery skills and connection to nature.
In fanfiction, it's possible through creative interpretations. Writers might use magic as a means. For example, they could create a unique spell that allows two female characters to have a child. It could also be a result of some magical artifact that has the power to make this happen. Another way could be through a magical bond that transcends normal biological limitations.
