In this fanfiction, perhaps the transformation into a baby for Infinite in Sonic Forces is a result of some sort of magic or experiment gone wrong. The story might then focus on how he interacts with the Sonic universe now that he's in this vulnerable state. He could befriend characters who were previously his enemies, as they see him in a new light. It could also explore how he grows and develops, even in his baby form, and how that might change his future when he eventually returns to his normal state.
Obviously, Sonic himself would be likely involved. He might be the one to discover baby Infinite. Tails could also be there, using his intelligence to figure out what happened to Infinite. Knuckles might get involved in protecting the baby Infinite. And of course, there could be other characters like Amy who would be interested in taking care of the baby.
