Hinata would be extremely shy but also very caring. She has always had a soft spot for Naruto. So, she would be blushing a lot around baby Naruto but also making sure he has everything he needs. She might even be the first to notice if baby Naruto is in any sort of distress and rush to his aid.
Sasuke would be suspicious at first. He's not one to trust easily. But once he realizes it's Naruto, he might see it as an opportunity to gain some new knowledge or power. He could also be a bit envious that Naruto has this time - traveling ability, thinking it gives Naruto an even greater advantage.
The villagers would have a mixed reaction. Some might be superstitious and think it's a bad omen that Naruto, a male, is pregnant and has time - traveled. Others, especially those who know Naruto well, would be more accepting. They would see it as just another one of Naruto's strange but ultimately positive adventures. And Naruto's friends like Shikamaru would be initially dumbfounded but then start thinking of strategies to deal with the situation and how to use it to their advantage.
Sasuke would be more guarded. He would see the dragon as a potential power source or a liability. He might keep his distance at first, observing how Naruto and the dragon interact. If the dragon proves useful in battles or in protecting the village, he might start to respect it more. As for Kakashi, he would be intrigued. He would likely give Naruto some advice on how to handle the situation, like how to train the dragon and keep it a secret if necessary.
Sakura might be a bit cautious at first. She'd worry about the fox being a danger or a distraction. But after seeing how Naruto cares for it, she'd warm up and might even help Naruto take care of it, like making sure it has proper food. Sasuke would probably be indifferent at first, but if the fox showed some useful skills in battle, he'd start to respect it. Shikamaru would just sigh and say it's too troublesome, but still offer some strategic advice on how to keep the fox hidden from enemies if needed.
Sakura would be overjoyed. She's been Naruto's friend for a long time, and she would be excited to see him start a family. She might offer to be the baby's doctor and make sure the baby is healthy. Shikamaru would probably be a bit lazy about it at first but would come around and offer his strategic mind to help protect the baby if needed.
Sakura would probably be really surprised at first. Since she was once in love with Naruto, it might be a bit of a shock, but she would also be happy for them. Sasuke might be more reserved in his reaction, but he would see Naruto's happiness and respect it. Shikamaru would likely be the one to make some sarcastic comments about how Naruto always manages to find himself in the most unexpected situations, but deep down he would be glad for his friend. Choji would be excited and would probably offer to share his food with the baby all the time.
Temari and Kankuro would probably be very protective. They've always been close to Gaara, and seeing him as a baby would bring out their nurturing sides. They'd do everything they could to keep him safe and find a way to turn him back. Naruto, on the other hand, would be shocked at first but then would see it as his duty to help. He has a strong sense of justice and friendship, and he wouldn't abandon Gaara in such a state.
If Harry went back to when his parents were at Hogwarts, his parents would be really confused at first. But then they would probably feel an instant connection to him. Lily might be very protective right away, while James would be curious and try to figure out how this baby got there.
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.
Another explanation could be that Teddy discovers an ancient and forgotten spell or artifact. He stumbles upon it while exploring some old wizarding ruins or in the Hogwarts library. This spell or artifact gives him the power to travel through time. And as he's always been an adventurous and curious character, he decides to use it to explore different time periods.
The Akatsuki members, if they were to encounter Naruto in this state, would have different reactions. Some might see it as an opportunity to target him when he's vulnerable. However, others like Pain, who has his own beliefs about the cycle of pain and suffering, might be a bit more conflicted. He might see Naruto's unborn child as a symbol of a new beginning or just another target. And the other Konoha ninjas, especially the younger ones, would look up to Naruto even more. His pregnancy and time travel situation would make him seem even more of an enigma and a source of inspiration as he's facing such unique challenges.
