While we planned on using a chunk of this for rebuilding my Jeep's engine, we ended up fully funding it already, so the $7k will go to:
$700 - fun money (saving up for a Vortex Razor 22-48x65 spotting scope)
$700 - give away
$5600 - invest
As for the $9600 we'll receive in child tax credit, that will all get invested and given away (90% & 10%, respectively)
The irony of all this is that the helicopter money is going straight into maxing our tax-advantaged accounts, which will increase our helicopter money next year, which will also go into tax-advantaged accounts, promoting a virtuous circle.
