I actually have a son but he his too little to know how a crypto wallet works, can't wait to see him grow so that I can teach him how to do it all, I plan to leave my Bitcoin wallet for him dead or alive it doesn't matter, my partner has his own separate Bitcoin wallet and I've never asked what he planned to do with his wallet. For now the goal is to live a healthy life for a long period of time, enough to raise kids into adults and guide them right so that all we worked for won't go to waste.
I hope you've intimated his mum at least on how to access the wallet, it is very good to prepare such inheritance for our kids, but more important to intimate a trusted person at least of how to claim the inheritance for them if you don't live long enough to pass it down yourself.
We pray for long life, but we cannot deny that anything can happen along the way, so we gats put contingent plans in place. I have kids, already created wallets for them individually and DCAing into it monthly for them(I don't want fights of any kind sharing their assets, so each of them has what is registered in their names), but their mom knows how to access everything and it interests her that it is done for the kids. I pray for long life, but if I'm not granted it, at least I want my children to be adequately catered for and there is nobody that would do that better than their mum and that's why I always carry her along in my investments and assets.
