Perhaps in the fanfiction, baby America starts to show unusual powers or abilities that he doesn't have as an adult. This could lead to various adventures. The other countries might have to protect him from those who would want to take advantage of a baby with such powers. They could also form a stronger bond as they take on this new role of caretakers.
Well, one possible plot could be that the other characters in Hetalia are initially shocked. They then have to take care of baby America.

Well, one possible plot could be that the other nations have to take care of baby Italy. They might struggle with things like feeding him, changing diapers, and getting him to sleep. Maybe they also discover new aspects of Italy's personality that were hidden before.
England could be one of the main caretakers. Despite their past differences, he would feel a sense of responsibility. Another could be Canada. Since they are related, Canada would surely step in to take care of his baby brother.
One idea could be that as America turns into a girl, there are cultural misunderstandings within the Hetalia world. For example, other countries might treat her differently based on gender stereotypes. Maybe she has to fight harder to be taken seriously in diplomatic meetings. Another plotline could involve her exploring her new identity and how it affects her relationships with other characters like England, who might have a very different dynamic with her now.
Well, one possible plot could be that Prussia, now as a girl, has to navigate the world of international relations in a different way.

Well, one possible plot could be that Italy's transformation into a girl causes chaos among the other nations at first. They are all used to his male self. But as time goes by, they start to see the new 'her' in a different light. Maybe 'she' brings a new perspective to diplomatic meetings or cultural exchanges. For example, the way 'she' approaches cooking and art might change a bit, adding a feminine touch to things that were previously more masculine in the eyes of the other nations.
Perhaps there's a treasure hunt involved. The pirates believe America has some clue to a great treasure because of his unique position in the world. So they take him along on their adventure, and along the way, there are lots of comical misunderstandings as America tries to explain modern concepts to the pirates.
