Good job!

This is important .. and becomes moreso as the value of your bitcoin increases. As a starting point, one other useful thing to do, if or when you have one, is to introduce your trusted bitcoin mate to your wife and daughter so they know who to reach out to for help if you go kaput! Post-kaput grieving for them isn't a time for clear, rational thinking, or recalling careful conversations that you're starting to have now. Having a trusted friend they can reach out to can be helpful for when they're ready.

And hopefully, this is many decades away! But! Good job on the forward planning :-)
