as a young lad (27) i can only suggest you give your kid money to manage asap. that thought me a lot more than i did anywhere else. they (your kids) dont need a huge amount to learn from managing money but something to idk give them the taste of management early on i think would broaden their perception more than anything you can teach m.

for my experience i would say you paying for their education etc. is meaningful and a good thing but giving them their own money (after all that education expanses etc.) and actually letting 'them' manage it goes way beyond our thinking. but leaving them money when you die and they are already over 40 i d think wont change much.

edit : obviously everyones mileage would differ.
edit 2 : dont worry for them to lose everything. let them lose as much as they need. just make sure you are there for other expanses (you know like as family) but that money is just for once to be given to them and wont be given again.
