Erin might be another character often featured. She could be a source of support for Eddie, like taking her shopping for baby clothes or just being there to listen when Eddie has pregnancy - related worries. Frank could also be in the fanfic. He might have a more paternal role, perhaps giving his blessing to Eddie and Jamie for this new chapter in their lives, or having a conversation with Eddie about how the Reagan family will welcome the new baby.
Jamie is surely one of the most common characters. As her husband, he would play a major role in the fanfic. He could be there for doctor's appointments, helping her with morning sickness, and sharing in the joys and concerns of the pregnancy. Danny could also be a key character. Maybe he gives Eddie some advice based on his own experiences as a father, or he could be involved in a case that somehow ties in with Eddie's pregnancy situation.
In addition to the main family members, some fanfics might include Eddie's friends from work. They could be helping her out with her duties when she starts to have difficulties due to the pregnancy. For example, they cover for her during a shift when she's not feeling well. And there could be interactions between them that show the camaraderie within the Blue Bloods world while Eddie is pregnant.
