One great idea for your grandson's birthday would be to get him a historical reenactment costume or clothing. Alternatively, you can look for accessories like hats, shoes, or jewelry that would complete such a costume. You can also consider getting him a book on historical reenactment or a biography of a famous historical figure. Another idea might be to surprise him with some tickets to a local historical reenactment event or even a trip to a historical site that he's interested in visiting.
Or you can get him a star map with the date when he was born.
