The theme of the baby having some sort of special or mysterious quality also pops up a lot. This gives an interesting twist to the story, as the characters have to deal with not only a baby but also the implications of this special quality, whether it's a connection to the supernatural world or some other extraordinary ability.
The idea of baby Dean being protected by the angels or other supernatural forces is also quite common. It often shows a different side of the Supernatural universe, with the focus on this tiny, defenseless version of Dean. And sometimes, there are time - travel or alternate - universe themes where characters from different timelines meet baby Dean.
Family dynamics is also a big theme. How does Sam react to being an uncle? How does Castiel fit into this new family situation? And of course, how does Dean interact with the mother of the baby, if she's in the picture? These are all aspects of family dynamics that are explored.
One common theme is protection. Dean, being a hunter, often has to protect the baby girl from various supernatural threats. Another theme is family. The baby girl becomes a part of Dean's makeshift family, and it shows how he adapts to having this new family member. And love, of course. Dean grows to love the baby girl deeply, which is a central part of these stories.
Family is a very common theme. Since Dean comes from a complex family situation, fanfics often explore his relationship with his father and brother at a young age.
