The Diamondback 2.5 years ago was a real monster truck and so it worked out pretty well to downsize it with a cut seat post, flipped swept handlebars, crank shorteners, smaller tires. I just undid the last of these. The fork was barely moving to begin with and taking a spring out was a change that will remain. It could still grow a bit, as it could take 26in tires as well as a riser bar and a longer stem in the 2000-2015 style, but there's a reasonable limit of course. I think we will make it to the end of next year at worst and possibly one more

I do have an idle MTB but it's a largish medium and the eldest kiddo is almost certainly not fitting on it yet. He's also a pretty timid rider and I've been considering getting him something more hybrid-cruiser-ish. But those kinds of bikes are just not cool, which is also important for kids (and anyone). I guess I could downsize it in a similar way.

2023 build after 2022 Christmas gift, recipient very large for his age but was still just turning six. He's 8.5 now and slowed a little by his leukemia bout but still above the line for percentile
