In fanfiction, Kushina might also interact with baby Naruto in a protective way when facing potential danger. Imagine a situation where some rogue ninjas are after Naruto for some reason. Kushina would put herself in front of Naruto without hesitation, using her chakra chains to fend off the attackers. And after the danger has passed, she would comfort Naruto, telling him that he is safe now and that she will always protect him.
Sasuke might be initially hesitant but then grow protective. For example, he could sense Naruto's loneliness as a baby, just like he felt his own, and start to look out for him.
Kushina would take care of baby Naruto very tenderly. She would make sure he is well - fed before sleep, perhaps by breastfeeding him or giving him a warm bottle. She'd also check his diaper and change it if needed.
Naruto would probably be in awe of them at first. He would be eager to learn from them, especially about the Uzumaki clan. He might ask Kushina about his father and her life in the village before he was born. With Mito, he could learn about the origins of the Uzumaki - Senju alliance.
Naruto might be really excited to meet Erza and show off his ninja skills. Kushina could be a bit more cautious, but she'd also be curious. Erza would probably be impressed by Naruto's determination, similar to her own. They could start by sharing stories about their respective worlds, like Naruto talking about his training with Jiraiya and Erza about her time in the Fairy Tail guild. Kushina could chime in with her own experiences in the Hidden Leaf village.
Obito might be initially hesitant and a bit awkward around Baby Naruto. But as time passes, he could develop a soft spot for the baby. He might play simple games with Naruto like peek - a - boo or make funny faces to make him laugh.
Jiraiya could also be one of the main characters. He was Naruto's mentor and had a connection with Kushina's family. He could play a role in helping them adjust to the time travel and also use their knowledge to his advantage in some ways, like getting intel on future threats.
In certain fanfic concepts, Naruto could have found a special relic or artifact. This relic might have the power to reverse death. Since Naruto is always on adventures and exploring different places, he might stumble upon such an item and use it to revive Kushina. It could also be related to the Uzumaki clan's secrets that he uncovers which enables him to bring his mother back.
They interact in a very interesting way. Naruto, being his energetic self, might be excited about all the new things in the modern world and constantly share his enthusiasm with Kushina. Kushina, as a mother, would be both amused and a bit worried, trying to keep Naruto in check while also enjoying his new - found joy. They could have simple conversations over a meal at a modern - style diner, for example.
Their relationship is often depicted as very loving. Kushina is a doting mother, always taking care of baby Naruto's needs.
Kushina's training in the fanfiction might also impact Naruto's mental state. Knowing that his mother is there to train him gives him more confidence. He feels more connected to his family and his Uzumaki heritage. This new - found confidence reflects in his battles, where he is more fearless and decisive.
