The adopted child could be a muggle - born with a great potential for magic. Maybe their parents were killed by dark wizards who were against muggles in the wizarding world. Harry and Hermione, having both experienced prejudice, would be determined to give this child a chance.
In a future fanfiction where Draco and Hermione have a child, the story could explore the challenges of their child growing up in a wizarding world still divided by old prejudices. The child might struggle with being a product of two former rival houses. It could also show how Draco and Hermione's relationship evolved over time, from enemies to lovers, and how they are now co - parenting. Maybe the child discovers a new form of magic that could bridge the gap between Slytherin and Gryffindor once and for all.
They are not common at all. The Boy Scouts of America has been around for a long time and has had millions of members over the years. While there have been some very publicized molester stories, these are the exception rather than the rule. The organization has made great efforts to prevent such abuse, including training programs for leaders, policies on appropriate behavior, and systems for reporting and dealing with any signs of abuse. So, while any instance of molestation is a tragedy, it's important to note that these are not widespread occurrences within the Boy Scouts.
Molesting is an extremely serious and immoral act, and such stories are very disturbing. We should not promote or focus on such inappropriate content. Instead, we should focus on positive family relationships, respect and protection within families.
They might face social challenges. In the wizarding world, there could be those who don't approve of their relationship or their decision to raise a child together. Also, financial challenges could arise. Even though they are heroes, they still need to provide for the child's needs, like education at Hogwarts which might have costs associated with it.
Harry would probably be very supportive. He knows what it's like to grow up without parents, and he would see Hermione's decision as a very kind and noble one. He might offer to help in any way he can, like teaching the child some of his own skills in magic or defense against the dark arts.
Draco Malfoy could also be a potential father in some 'Hermione Secret Child Fanfiction'. Their relationship in the original series was one of rivalry, but fanfiction often takes unexpected turns. The idea of a relationship between them, perhaps in a post - war world where they put aside their differences, could lead to the birth of a secret child, which would add a whole new layer of drama and intrigue to the story.
Obviously, their child is a very popular character. But also, the friends of their child at Hogwarts, like a new generation of Gryffindors or other house students. There could be a character who is a descendant of an old wizarding family that has a special bond with Harry and Hermione's child.
