Fics like My Dad the Genius, Billionaire, Playboy

This is a My Son the Wizard AU. Petunia discovers her sister’s journal revealing Harry’s true parentage years earlier than in My Son the Wizard. A much more reckless and irresponsible Tony Stark now has custody of his five-year-old magical son. Will he decide to raise him or will it prove too much responsibility for the playboy? Will he turn into the type of father he always feared he’d be?
