I second any recommendation for a kde based distro. Ubuntu or it’s derivatives are the easiest place to start. Kubuntu is the kde based flavor iirc.
My daughter just turned 6 and is competent with a mouse and keyboard. They have kid friendly houses and keyboards on Amazon for cheap. She’s been daily driving slackware since she was 4 and has no idea how badass she is yet.
Gcompris is a great app. It’s a bunch of games for kids to learn letters, typing, mouse skills and some stuff just for fun. Install it on whatever distro you land on. Also, tuxpaint.
No. I’m about to change my number because I get so many spam calls and texts.
