Hello! Let's say a 20 y.o character died and got reincarnated (with his full consciousness and memories) as a baby. Would he age mentally too? As in, if his body was 10 y.o, does this mean that he's mentally 30? And what would be the drawbacks of his situation?
I hate to burst your bubble, but this falls firmly into the realm of breaking Aunt Scripty’s rule of reality.
Memories and consciousness are linked to the physical structures of the brain. Babies’ heads are simply not capable of holding all the information stored in the adult brain.
That’s not to say you can’t write your story the way you want to; just be aware that you can’t base this part on reality.
