Apart from kids being your kin, how do you know now (assuming that your kids are still very young) that they are or will be worthy of such inheritance?
Actually, a serious question and I have been grappling with this one for a while.
Alternatives: extended family (if worthy), charities of your choosing, etc, etc.
They are your kids. Do you have children?
The more pertinent question is whether it will actually advantage them and whether they are equipped to handle it.
