There are many possibilities. Maybe the boy has an uncanny connection to a particular place or person from the past, and his parents think it's a sign of reincarnation. Another story could be that the boy starts speaking a language he's never learned before, which convinces his parents he's the reincarnation of someone who knew that language.
There are quite a few. One could be about a boy who shows strange behaviors and knowledge that his parents think can only be explained by reincarnation. Another might involve a boy who dreams of past lives and his parents start to believe it.
Well, you could have a story where the boy has memories of events he couldn't have experienced in this life, and his parents are convinced it's because he's reincarnated. Or perhaps a story where the boy has skills or talents that seem out of place for his age and background, leading his parents to believe in reincarnation.
