If you want your kids to grow up with Math talent, start young in Music, be it playing simple drum or flute, later at age 4 or 5 progressing to piano or violin, along the way pick up musical theory…
Notice that great mathematicians (or Physicists the close cousins of Math) are often music talents, but the converse not true! Einstein performed violin with an orchestra formed by a group of Nobel Prize Physicists; never heard Mozart or any great musicians proofed any Math Conjectures.
