The family house - elf could be an important character. It could be the one who takes care of the family home and the kids when Harry and Draco are away on magical business. It could also be a confidant for the children, listening to their problems. And Dumbledore's ghost could make an appearance. He could offer some cryptic advice to Harry and Draco about raising their family in the wizarding world, guiding them to make the right decisions for their family's future.
One possible plot could be that after years of rivalry and then gradually getting to know each other better, they realize their mutual attraction. They might start a relationship secretly at first. Then, they decide to adopt a child together. They face challenges from the wizarding society that still has some old - fashioned views about their relationship. But they stand strong together and build a loving family environment for their child.
Hermione could be a main character. She might be the one who discovers Draco's situation and tries to help him out of pity or a sense of justice. Harry could also be involved, perhaps initially being suspicious of Draco's new state but then realizing it's not a trick.
Hermione could be a main character. Given her strong stance on equality, she might initially be suspicious of Draco but later come to understand his internal struggle as a half - blood. Their interactions could be filled with tension and, eventually, mutual understanding.
Harry Potter would surely be one of the key characters. His relationship with Draco, which has always been a mix of rivalry and grudging respect, could play a huge role. As Draco switches sides, Harry would be initially suspicious but then come to accept and work with him. Hermione Granger is also likely to be important. Her intelligence and strong moral compass could influence Draco further and she could be the one to first recognize his change of heart.
Hermione is often a popular character. She might be the one who discovers something unusual about the toys and helps Harry and Draco understand their significance. Ron could also be there, perhaps getting into some comical situations because of the toys. And sometimes, even the teachers like Dumbledore or Snape can make an appearance, maybe guiding Harry and Draco in their toy - related adventures.
Snape can also be a prominent character. Given his history with both Harry and Draco's families, his reaction to their deaged state can add a lot of drama. He could be torn between his duties as a teacher and his complex feelings towards the two boys. Additionally, Dumbledore is often included. His wisdom and guidance are crucial in helping the deaged Harry and Draco figure out what has happened to them and how to move forward.
Narcissa Malfoy could also be important. As Draco's mother, she might have mixed feelings about the situation. On one hand, she wants to protect her son, but on the other, she might see the potential good in Harry and Draco working together for the baby's sake.
Another possible main character could be Snape. Given Snape's complex relationship with Draco in the original series, in this fanfiction, he could be either a mentor to Draco in his prodigious journey or have a more conflicted role as he tries to balance Draco's new status with the existing power structures in Hogwarts.
Harry Potter could be one of the main characters. Since he has a complex relationship with Draco, he might be intrigued by Draco's sleep - talking and try to use it to gain some understanding of Draco or even to tease him.
They could go on an adventure to find a hidden magical artifact that was lost in the Forbidden Forest. Along the way, they'd face all kinds of magical creatures, like the centaurs and thestrals. They might have to use their combined magical skills, Harry's Gryffindor bravery and Draco's Slytherin cunning, to get past the obstacles.
