Another theme is discovery. As a baby, Naruto is full of potential. Fanfictions often explore the discovery of his powers or his unique connection to the Nine - Tails at a very young age. For example, some stories might have baby Naruto unknowingly using a bit of the Nine - Tails' chakra in a moment of distress, which then leads to a whole new plot about how the village reacts.
One great little baby Naruto fanfiction is 'Baby Naruto's New Family'. It shows a heart - warming story of Naruto as a baby being taken in by a kind family in the village. They protect him and raise him with love, which is a really nice deviation from his usually lonely start in the original story.
Well, it's mainly baby Sasuke and baby Naruto. But sometimes other characters from the Naruto universe might make an appearance in the fanfiction. For instance, Iruka Sensei could be the one looking after them, or Sakura as a baby might be in the background. However, the spotlight is mostly on baby Sasuke and baby Naruto as they are the ones around which the whole concept of this fanfiction revolves.
It could be Hinata. Since they are in a relationship in the original series, it would be a natural choice. Hinata would be a loving and caring mother, and her gentle nature would be a great influence on the baby.
In a fanfiction world where Naruto and Rin have a baby, it could be a very interesting story. Maybe the baby would inherit Naruto's positive attitude and Rin's kindness. The story could explore how they raise the child in a world full of challenges and ninjas.
One idea could be that the baby is from a hidden clan. Naruto decides to protect the baby from those who would use its special abilities. He takes the baby under his wing and trains it as it grows up, passing on his ninja values.
One possible character could be Jiraiya. He was Naruto's mentor later in life, but in a fanfiction, he could have taken Naruto as a baby. He had a close relationship with Naruto's father, so it would make sense for him to take Naruto under his wing from the start. Another could be Tsunade. As one of the Sannin, she has the power and the means to protect Naruto. Plus, she might have seen it as her duty to take care of the son of her old teammate.
Naruto uses his ninja skills. He's always on high alert, using his enhanced senses to detect any potential danger. His quick reflexes mean he can react in an instant if anything threatens the baby.
Fanfiction based on 'Hush Little Baby' could be about various things. It might be a modern retelling of the lullaby in a fictional world. For example, it could be set in a fantasy realm where the 'hush little baby' is actually a magical infant and the items mentioned in the original lullaby have special powers in this new story.
Sasuke could influence baby Naruto's growth by teaching him discipline. Naruto as a baby would be impressionable, and Sasuke's strict ways could instill a sense of self - control in him early on.
