One possible plot could be that the baby boy is in a new and strange environment. Maybe he's been adopted into a family in a fanfiction world. He's confused because the new family has different customs or appearances than what he's used to. His crying could be a way to express his discomfort and fear. For example, if it's a fantasy fanfiction, the family could be elves or some other non - human species.
To make it engaging, add some mystery. Let the readers wonder why the baby boy is so confused. Is it something supernatural? In a horror - themed fanfiction, perhaps there are unseen forces that are causing his distress. His crying could be a signal that something bad is about to happen. You can also use dialogue, even if it's just the baby boy making incoherent noises at first, and then gradually as the story progresses, he might start to communicate in some strange way.
One possibility is that the story focuses on how Raven and Beast Boy adjust to being parents. They might face difficulties like protecting their baby from villains who want to use the baby's powers for evil.

The baby boy could be crying because he's hungry, tired, or feeling scared. Sometimes it could be as simple as not getting what he wants at the moment.
Maybe he lost his favorite toy or got scolded by his parents.
Maybe he's lost or scared. That's often a reason for a baby to cry in cartoons.
It could also be that Whitney is separated from her Pokemon. For example, there could be some sort of Pokemon - stealing gang in the story. They manage to take her Pokemon away from her. She loves her Pokemon like family, and the thought of being without them makes her break down in tears.
One possible plot could be that the baby boy inherits Sasuke's Sharingan. This leads to many challenges as they have to protect him from those who might want to use his power. Sakura, with her medical skills, tries to find a way to control or at least understand the implications of the Sharingan in a young child. Meanwhile, Sasuke trains the boy in self - defense, passing on his ninja skills in a more gentle way compared to how he was trained.
A confused cartoon boy might be confused because of new and unfamiliar circumstances. It could also be that his expectations were not met, or there's a mystery he's trying to solve but keeps hitting dead ends.
The image of a baby crying boy in a cartoon might be there to engage the audience's sympathy or to set up a problem that needs to be solved within the cartoon's storyline.
One possible plot could be that Freebat has some sort of misunderstanding with Billy. Maybe Freebat accidentally breaks Billy's favorite item, which makes Billy start crying. Then the fanfiction could explore how they resolve this conflict, perhaps through a series of apologies and reconciliations.
