The main characters would be Itachi as a baby, for sure. Then, the people in his village, like the elders or other ninja who knew him before. They would be trying to figure out what to do with this baby Itachi. Additionally, any friends he had made during his time as a normal ninja could be main characters. They might be worried about whether he'll ever turn back to normal and how to keep him safe in the meantime.
Obviously, Itachi as a baby would be a main character. Sasuke would also be a key character as Itachi's brother. Their relationship would be very different now that Itachi is a baby. Naruto could also be involved, perhaps being curious about this strange transformation and wanting to help out in some way.
