We set up accounts for our 15 yr old beginning before she was born. I think it is SO important to get a child through college and out of the nest debt free.
My hubby is a numbers man as well as well thought out planner. We had everything set up before we went with our planner. Our financial planner is someone who can guide our daughter in the event we are dead and gone OR if she thinks she is much smarter than us (most kids do around this age.....parents are clueless).
We do have a fully funded 529 in her name. We also have a large coin collection, collection of savings bonds and other savings accounts for her.
Our daughter does want to study abroad and we are planning for that as well.
Kudos to you for planning ahead. Whatever monies our daughter does not use can be used for her children/grandchildren's education.
Good luck.
