Draco's character could develop in terms of his values. With a daughter, he might start to question the pure - blood ideology he was raised with. He realizes that love and family are more important than blood status. He may even start to advocate for a more equal wizarding society so that his daughter can grow up in a better world. He becomes more of a protector, not just of his family name but of his daughter's future and well - being.
Her character could develop through her relationships. If she has a best friend who is from a completely different family, like a Weasley - like family, she would be influenced by their values.

In the Muggle world, he's forced to confront ideas and ways of life that are completely different from what he knew in the wizarding world. This can make him more empathetic towards others.
