FIRE’d, now how do I update my will for kids to learn to hustle

If my husband and I died right now, our kids would be instantly LeanFIRE’d when they turn 18. I’m planning to spread out the timeline to 15% at 22, 25% at 25, and the remainder at 30. But even then how much is too much? Too little? I have not and will not inherit money (although I will get a piece of forested land). Hubby thinks give it all to the kids. I think anything over mid-six-figures is overkill and I’d rather help charities at some point. How did/will you decide? If you inherited wealth, did it change your behavior, and how?
