First, Magnus would probably use his extensive knowledge of magic to create a sort of magical cocoon around Harry's living space. This cocoon would not only prevent dark forces from entering but also mask Harry's presence. He'd also be in contact with other powerful magical beings who could provide additional protection. Magnus would make sure Harry is always surrounded by positive magic, for example, by filling the room with enchanted light that repels darkness. He would train Harry's natural magical abilities early on so that Harry can have some means of protection even when Magnus isn't right by his side.
Magnus would likely use his powerful magic. He could create wards around the place where Harry is staying. These wards would be strong enough to keep out any dark wizards or creatures. He might also give Harry a charmed amulet that has protective spells on it.
Magnus could set up magical alarms that would go off if any dark force comes near. He'd be constantly vigilant, using his magic to sense any approaching danger. He would also teach Harry some basic self - defense magic, even at a young age, like how to create a shield around himself. And he'd probably have some magical allies on standby to help in case of a major threat.
One heartwarming scenario could be Magnus using his magic to create a beautiful, enchanted nursery for baby Harry. He could fill it with floating toys and a crib that rocks itself gently. Another might be Magnus cooking special baby food for Harry with a touch of magic to make it extra delicious and nutritious. Maybe he'd also read him magical bedtime stories that bring the pictures to life on the walls of the room.
One challenge could be understanding baby Raphael's needs. Since Magnus may not have had much experience with babies, he might struggle to figure out why Raphael is crying - whether it's because he's hungry, tired, or in need of a diaper change.
The story could explore the bond that forms between Magnus and baby Raphael. Since Magnus has such a long life and a lot of experiences, he would be in a unique position to shape Raphael's early life. He might tell Raphael stories of his adventures, and as Raphael grows, these stories could inspire him to be brave and kind.
Harry might first try to figure out what's wrong. If the baby is hungry, he'll quickly get a bottle. If it's a wet diaper, he'll change it. Sometimes, he just holds the baby close and rocks it gently, humming a little tune. He doesn't get frustrated easily because he really cares about the baby.
Maybe it's the child of one of his friends or allies. For example, it could be the baby of Ron and Hermione. Harry would then be taking care of the baby out of loyalty and friendship.
Harry is known for his kindness and loyalty. So, he would take care of Draco with a lot of patience. He would probably stay up all night if Draco was fussy, just to make sure he was okay. His protective nature would also mean he'd keep Draco safe from any harm, whether it's from other wizards or just from the general dangers in the wizarding world.
In the fanfiction, Harry's relationship with Snape himself would of course be very different. When Snape grows up, he might have a different view of Harry. Since Harry took care of him as a baby, there could be an underlying sense of gratitude, although Snape might not show it openly. And Harry, having seen Snape as a vulnerable baby, might have more empathy for him in their later interactions, which could change the whole dynamic of their relationship compared to what we see in the original books.
Naruto would use his Sharingan - like observational skills. He's used to being aware of his surroundings in the ninja world. So he'd be on high alert for any danger. If any dark wizards came after Harry, Naruto could use his speed to get Harry out of harm's way quickly.
He might become more selfless. Usually, Draco is quite self - centered, but with a baby Harry to look after, he has to think about someone else's needs first. For example, he might sacrifice his own comfort to make sure Harry is warm and fed. Also, he could become more responsible as he has a life in his hands, and any mistake could be costly for Harry. This would be a huge change from his carefree, sometimes reckless, self.
Sirius could use his knowledge of the wizarding world's secrets. He might know some hidden places or spells that could keep Voldemort at bay. For example, he could put a powerful protective charm on the place where Harry is staying.
