Their relationship could develop through shared secrets. For instance, Harry might tell Teddy about some of the things he never told anyone, like his innermost fears during the fight against Voldemort. Teddy, in turn, confides in Harry about his struggles with growing up different. This mutual trust deepens their bond.
At first, it might be a bit rocky as Teddy is a young boy dealing with the loss of his parents and Harry is still learning to be a father figure. But as time passes, they start to bond over simple things like Quidditch. Harry teaches Teddy how to fly a broomstick, and this shared activity brings them closer.
Initially, Harry's raising of Teddy would be based on his love for Teddy's parents. But as time progresses, he would develop his own unique bond with Teddy. They would go through normal family things like holidays and birthdays together. Teddy would rely on Harry for advice on school, friendships, and magic. Harry would be there for Teddy through all his ups and downs. As Teddy becomes a teenager, there might be some clashes in their personalities, but they would always come back together, and their relationship would be one of the most important in both of their lives.
In some Harry Potter fanfictions about Teddy Lupin's time travel, he might go back to prevent certain tragedies. For example, he could try to save his father Remus Lupin from the final battle. He might use his knowledge of the future to change the course of events, perhaps by warning the Order of Phoenix earlier about Voldemort's plans.
Their relationship could start as a simple acquaintance at Hogwarts. As they participate in school activities like Quidditch matches or wizard duels, they gradually become friends. Then, as they grow older, they might realize they have deeper feelings for each other.
He could change the outcome of the war. If Teddy went back in time, he might be able to tip the balance in the fight against Voldemort. He could use his knowledge of advanced magic from his own time to outwit the Death Eaters.

Well, perhaps in the fanfiction, Harry adopts Teddy Lupin right after the Battle of Hogwarts. Teddy is just a baby then. Harry, who has lost so many people, sees Teddy as a new beginning.

But Harry, with the help of his friends like Hermione and Ron, overcomes these difficulties and Teddy grows up to be a strong and kind wizard.
Well, first of all, Harry would have to adjust to the new setting of Forks. He would be raising Teddy in a place very different from the wizarding world. Teddy might start to show some interesting magical abilities that would be quite a novelty in Forks. Harry would have to be careful not to expose magic too much, while still teaching Teddy about his heritage. And he would probably make some new friends in Forks who would be intrigued by his different ways.
At first, Harry might be a bit skeptical of Kakashi. But as Kakashi starts to show him new skills and ways of thinking, Harry would grow to respect him. Kakashi, on the other hand, would see Harry as a young protege with great potential.
