Ron Weasley could be included. His friendship with Harry and his own skills (even if he's not as good as Harry or Ginny at Quidditch) could bring some comical moments. He could be the team's cheerleader or the one who always has a joke to tell in the locker room to ease the tension before a big match.
Hermione and Ron are great choices. They are Harry and Ginny's closest friends. Hermione can add her intelligence and practicality to the story, like helping with the wedding preparations or giving relationship advice. Ron can bring in his humor and loyalty. His reactions to Harry's engagement can also be quite entertaining, like being a bit jealous that Harry is getting married first.
Luna Lovegood would be a great addition. Her unique perspective on magic could offer new insights to Teddy. Also, Ron could be included as Harry's best friend. His humorous and sometimes clumsy nature could add some light - hearted moments to the story.
Hermione would be a great addition. She could be the one who accidentally discovers their secret and then has to decide whether to keep it or tell Ron. Neville could also be involved. Maybe he stumbles upon them in the greenhouse while they're having a secret moment and he becomes their accomplice in keeping the secret.
Hermione could be a great addition. She's Harry's best friend and Ginny's sister - in - law. She could offer advice to both of them during their relationship struggles. For example, when Harry is too busy with his Auror duties and Ginny feels neglected, Hermione could step in and help them communicate better.
Neville could be another important character. He could be like a godfather to their children, teaching them about Herbology and sharing his own experiences of growing up in the wizarding world. Luna could also be involved. She might bring some of her unique and dreamy ideas to the family, like introducing the children to some strange but fascinating magical creatures she discovered. And of course, the Weasley family as a whole would be very much present, with Molly Weasley spoiling the children with her delicious magical cooking.
Ron can also be included. He might be a bit clueless at first about their relationship, but then he can become a source of comic relief as he tries to play matchmaker or accidentally gets in the way of their romantic moments.
One possible storyline could be Harry and Ginny training a young and talented rookie on their professional Quidditch team. They could face challenges like the rookie having self - doubt and the two of them using their own experiences to boost the rookie's confidence.
Ron and Hermione could be main characters. They are Harry and Ginny's closest friends. Hermione might offer her vast knowledge of magic to help with any problems the baby has, like if there are some strange magical symptoms. Ron could be there for comical relief, making jokes about how Harry has become a proper family man now.
Adding Draco Malfoy could create some interesting drama. He could use Harry and Ginny's jealous games to his advantage, maybe trying to drive a wedge between them. And of course, the Weasley family as a whole. Molly Weasley could notice Ginny's behavior and have a motherly talk with her, while the other Weasley siblings could have different reactions to the whole jealous situation between Harry and Ginny.
Hermione and Ron are great to include. Hermione can help Harry and Ginny with their studies and also be part of their anti - Umbridge plans. Ron can add some comic relief and also be a good friend to both of them during this year.
