It might be a story of how Sam and Freddie's relationship changes with the arrival of the baby. At first, they could be stressed and argue a lot more.

In the fanfiction, the plot might start with Sam and Andy deciding they are ready for a baby. They start trying, and when they finally get pregnant, it's a time of great joy.

Well, one possible plot could be that they initially struggle with the news. Sam might be worried about how to support Bella and the baby. Maybe there are family or friend reactions to deal with, like some being shocked or disapproving.
Another theme is the idea of redemption. Some fanfictions have Jessica coming back in some way, and Sam sees it as a chance to make things right, to protect her better this time.
