As I don't know the story well, the main characters are probably the parents of the son who is born. Maybe there are also other family members or friends who play important roles in the story.
Given that it's a story about a son being born, the obvious main characters would be the mother and father. The mother would be central as she goes through the process of giving birth. The father may be depicted as being supportive or having his own set of emotions during this time. There could also be grandparents or siblings if it's a story that expands on the family unit. Additionally, there might be a midwife or a doctor if the story details the birth in a more clinical or traditional way.
