Well, it could have the power of enhanced empathy. Since Jacob has his wolf abilities which are connected to the pack's emotional bond and Renesmee has her special gift of projecting her thoughts and memories, their baby might be able to sense and even manipulate the emotions of those around it on a much deeper level. It could also have a form of telepathic communication that is stronger than Renesmee's, being able to communicate not just with vampires and werewolves but also with other supernatural creatures if they exist in the fanfiction world.
The Cullens would probably be very protective. They've always been protective of Renesmee, and with the addition of a baby, they would likely do everything they could to keep it safe. Bella and Edward would be overjoyed grandparents, and they'd use their combined knowledge and powers to ensure the baby's well - being. The werewolf pack might be a bit more hesitant at first. Jacob's relationship with the pack has been complex, and a half - vampire, half - werewolf baby would be a new concept for them. But ultimately, they would also come around to protect the baby because of their loyalty to Jacob.
If Renesmee and Jacob had a baby in fanfiction, the story could go in many directions. Their baby could be a symbol of hope and unity between the vampires and werewolves. It might grow up to have a special role in bridging the gap between the two groups. Also, the baby's growth and development would be unique. It could face challenges that are different from normal humans or even regular vampires or werewolves, like dealing with the expectations of both communities and finding its own identity in a world that is still getting used to the idea of their relationship.
Their relationship would likely become more centered around the baby. They'd have a new focus in their lives, which would bring them closer as they share the responsibilities of parenting.
One possible reason could be that Renesmee simply has different interests. Maybe she is more drawn to a different lifestyle or set of values that Jacob doesn't align with. For example, she might be interested in exploring the world in a more solitary way while Jacob is more about the pack and community.
Another reason could be to protect her from a prophecy. In the world of fanfiction, there could be a prophecy that foretells Renesmee's doom if she stays with the Cullens. So Jacob, thinking he's doing the right thing, kidnaps her to keep her away from that fate.
