The baby could be the child of a fallen ninja. Maybe the ninja was an ally of Naruto's and before dying, entrusted Naruto with the baby. This would add an emotional depth to the story as Naruto would feel a great sense of responsibility to raise the baby well.
One idea could be that Mikoto discovers baby Naruto alone and decides to take him in and protect him, raising him alongside Sasuke. This could lead to a very different dynamic in the Uchiha clan and Naruto's growth.
One possible scenario in this fanfic could be that Naruto discovers the baby fox while on one of his adventures in the forest. The baby fox might be injured or lost, and Naruto's kind heart leads him to take care of it. Their snuggles could represent the bond of trust and friendship that forms between them. It could also be a symbol of Naruto's connection to the natural world in the Naruto universe.
A fanfic about Naruto and Tsunade having a baby could start with an unexpected situation. Perhaps a powerful enemy forces them to be together and they end up having a child. The baby's growth would be a central part of the story. It could struggle with living up to the reputations of its parents. On the other hand, it could also find its own path. It might befriend characters like Boruto and Sarada and create a new generation of friendships in the Naruto world.
Another theme is his potential as a ninja even as a baby. Fanfics often explore how his natural talents start to show early on, like his strong will and determination that are already evident in his infancy. They might also show how some of the villagers start to notice these things. For example, in some fanfics, an old ninja might see Naruto's determination when he tries to crawl towards something and realizes he has the makings of a great ninja.
There's no way for me to tell who the author is just from the title 'kyuubi baby a naruto fanfic'. It could be someone who is really passionate about Naruto and the concept of the Kyuubi in a different form. To find the author, you might want to check popular Naruto fanfic archives or forums where fans discuss and share fanfics like this one.
I'm not sure specifically as I haven't read it. But generally, a Naruto fanfic with 'Kyuubi baby' in the title might be about the nine - tailed fox (Kyuubi) in some form of a baby or new - born state within the Naruto universe. It could involve how this Kyuubi baby affects the story, the characters like Naruto who has a connection to the Kyuubi, and perhaps new adventures or relationships that form because of it.
Yes, there are likely some family - friendly 'naruto and shion baby fanfics'. Some authors might focus on the cute aspects of Naruto and Shion having a baby, like how they would take care of it, the baby's growth in a positive and innocent way within the Naruto universe. For example, they could write about the baby inheriting unique ninja abilities from its parents in a non - violent and heartwarming context.
One great fanfic is 'The Early Days of Naruto' which beautifully depicts Minato and Kushina's relationship with baby Naruto. It shows their tender moments together and how they start to teach Naruto about the ninja world from a very young age. Another good one is 'Naruto's Family Beginnings' where the focus is more on the family dynamic. You can really feel the love Minato and Kushina have for their baby. And then there's 'Baby Naruto's World' which goes into detail about how Naruto's presence affects the village even as a baby, and how Minato and Kushina are at the center of protecting and nurturing him.
Kurama might be a bit confused at first. A baby is not what he expected to see. He could be less aggressive than when Naruto is older. Maybe he'd just watch the baby Naruto curiously.
