Am I Actually the Strongest? (Light Novel)

To be reincarnated into another world with the promise of a "cheat" power is one thing... but to be reborn as a baby, and then left for dead after your royal parents think you're powerless?? That's another thing entirely! Now the newly-born Reinhart—or Hart to his new friends—must find his way through a dangerous world...but luckily he's got magic that's quite literally off the charts!
