re: savings for grandchild

I would want them to have it for school if needed, if they don't go to school, or if they do and there is money left I would like for them to get their first house, car or invest it themselves if they choose to do so.
The trust is a good idea, it's what we are looking to do for ourselves here soon. I am going to do some more digging on the 529 also. Thanks for input
