One interesting plot point could be that the baby boy is born with a mark that gives him access to a secret realm. Bella has to figure out how to keep him safe from the dangers of this realm while also allowing him to explore and learn about his connection to it. Additionally, the baby boy could have an innate wisdom that surpasses his age, and he starts guiding Bella and those around him in unexpected ways.
A great plot point could be that the baby has a unique magical ability that no one has seen before. This could attract unwanted attention from dark wizards who want to use the baby's power for their own evil purposes. Harry and Ginny would then have to go into hiding and use all their skills to keep the baby safe.
One possible fanfiction could be that Bella's journey through pregnancy is filled with unexpected challenges. She discovers new powers within herself that she passes on to her unborn baby boy. The baby boy, when born, has a special mark on his hand which is a sign of great things to come in the magical world they inhabit.
A really interesting plot point would be the baby's development. Since it's a vampire - human hybrid, it might have some extraordinary powers even in the womb. This could lead to some dangerous situations, like attracting other vampires or werewolves. Also, Bella and Edward could start planning for the future, like where they will raise the baby and how they will educate it about its unique heritage. They might also face challenges from the vampire community who might see the baby as a threat or an abomination.
In fanfiction, their baby boy might inherit special powers from both of them. He could have Edward's vampire speed and Bella's ability to resist vampire powers. The story might focus on protecting the baby from vampire enemies who see the new hybrid as a threat.
Well, one possibility could be that the baby has some special powers right from the start. Maybe it can communicate with the vampires in a unique way that no other vampire - human hybrid has before.
Well, it could be about how Bella and Edward adjust to parenthood. Bella might struggle with her new role as a mother while still being a new vampire. Edward, on the other hand, could be overly protective. Their relationship might also change as they focus more on their baby's needs.
One possible plot could be that the baby boy inherits Sasuke's Sharingan. This leads to many challenges as they have to protect him from those who might want to use his power. Sakura, with her medical skills, tries to find a way to control or at least understand the implications of the Sharingan in a young child. Meanwhile, Sasuke trains the boy in self - defense, passing on his ninja skills in a more gentle way compared to how he was trained.
Well, perhaps Bella's sister is a half - vampire herself. She was born from a vampire who didn't fully turn her mother. This sister could struggle with her identity, not fully fitting in with either humans or vampires. She might be drawn to the Cullens because of their 'vegetarian' lifestyle but also be scared of them. She could also be friends with Jacob before Bella even arrives in Forks, and Jacob has to keep her secret from Bella until the right time.
Well, in a fanfiction like this, it could start with Bella and Paul already in a relationship. When they discover the baby is on the way, they decide to move in together to prepare for the new arrival. Paul might start taking odd jobs to earn extra money for the baby. Bella could be documenting the whole pregnancy journey in a diary. And as the due date approaches, they might have a baby shower organized by their closest friends, and finally, the baby is born, bringing a new kind of joy to their lives.
Another plot could revolve around Bella, Edward and Renesmee going on a journey to discover more about Renesmee's origins. They could meet other hybrids or ancient vampires who have knowledge about her kind. This would not only be an adventure but also a way for the family to bond more.
