Djinn wish expert here. No knowledge of the the past means all of your memory prior to whatever age you decided to land on is erased. No influence outside of the timeline means all choices the child you makes would be the same. The person who made that Faustian bargain wouldn't exist up until the very point at which they make the wish again. Actually you'd be trapping all of existence into an inescapable time loop just for nostalgia you couldn't even appreciate anymore.
