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.
One idea could be that baby Harry goes back to the time when his parents were at Hogwarts. He could accidentally change some small events that end up having a big impact on the future. For example, he might cause his parents to meet earlier or in a different way.
Dumbledore would probably take it in stride. He has seen many strange things in his long life. He might see it as a chance for Harry to experience a different perspective, and with his twinkling eyes, he would watch the whole situation unfold with amusement and a bit of wisdom, knowing that it's all part of the magical world's unique charm.
Well, in the fanfiction, if we consider the people around Harry, the teachers at Hogwarts could be concerned at first. Dumbledore, being the wise figure, might see potential in the baby and encourage Harry. As for Edward's friends in the vampire coven, they would have mixed feelings. Rosalie might be jealous as she always wanted a normal life with a baby. Jasper might be worried about the baby's influence on their coven's stability. But overall, as time passes, they would adapt and form a new kind of community around the baby.
Most of Harry's friends from Hogwarts would be surprised, but they would quickly show their support. Neville, for instance, would be happy for them and might offer to help with any magical plants that could be useful for the baby, like those with calming or protective properties. The other Aurors that Tonks works with would probably be a bit more reserved in their reactions, but they would respect their colleague's decision. And the centaurs in the Forbidden Forest, if they were aware, might see it as a sign of new beginnings in the wizarding world, a new life that could bring balance or change to the magical realm.
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.
Well, their friends' reactions would be a mix of surprise and joy. Some, like George, might make jokes about how Harry and Hermione finally got together. But deep down, he would be happy for them. The other Hogwarts professors, like McGonagall, would be proud to see two of their best students starting a family. She might even offer to babysit on occasion. The friends would also come together to throw a big celebration for the baby's birth, and it would be a time for the wizarding community to celebrate the new addition and look forward to a bright future with this new generation.
Well, he would have a second chance at life. Since he was a baby, he could grow up with different relationships. He might form stronger bonds with his parents and be able to learn more about his family. Also, he could start training earlier and become an even more powerful ninja. With his knowledge from the future, he could also help the village in new ways, like coming up with better strategies against enemies.
Evie would be the doting aunt. She'd be constantly making little outfits for the baby and spoiling it rotten with cute accessories. Jay would be the cool uncle, teaching the baby little tricks and showing it how to be brave. Carlos would be a bit more cautious but would also be very protective, always making sure the baby was safe. As for the other characters in Auradon, they'd be excited and curious, seeing the baby as a symbol of the new unity between different worlds.
Their friends from the Isle of the Lost might be initially shocked but then very supportive. They would probably see the baby as a new hope or a symbol of a different future. For example, Uma might be hesitant at first but then realize that the baby could be a bridge between different factions.
Ron might laugh out loud at first. He has a good sense of humor and would find the whole situation hilarious. But then he would also be a bit worried about Harry's dignity. Ginny, on the other hand, would probably blush and giggle. She has a bit of a crush on Harry and seeing him in such an adorable yet silly state would be both endearing and embarrassing for her.
