Put half the money in a fund for the kid's college or to buy a house when he is an adult and put the other half in a fund for him to climb Everest when he is over 18, and an adult, and on his own, without Mom and Dad.

People with that kind of money to blow don't care about college funds, other than 529 plans, and Everest has ceased to be a big deal years ago when it became a tourist destination. Have him sail single handed across the Pacific or enter him in the Tour de France....that would get my attention. grin
Money buys 'accomplishment' these days,including 'astronaut'...which at one time was a monumental thing.
