I picked up LOGO when I was 6 and leant Pascal and C later. I didn't program for a few years because I wasn't interested in competitions. So I think interest is the most important, otherwise it will be easy to get lost and give up. Later, I became very interested in programming, mainly because I came into contact with music technology. I think since your child is interested in game development, it is a good choice to start step by step. For example, starting with threejs. I also recommend learning Rust and Bevy so you learn the underlying layers and ECS. Last but not least, although it's not related to games dev but I sincerely invite you and your son to try Glicol (https://glicol.org https://glicol.org), a music programming project that I am developing.
