Trumpet and life...

Recently I saw a post here about someone who'd spent much of his youth and young adulthood invested in trumpet, and was now rueing all the years and effort. One takeaway is that one needs to practice all the time to maintain skills. A professional we know has said that if he skips a day of practicing, he can tell. Skipping 2 days, and others can tell.

So- for those of you who aren't professional trumpet players, but identify with being a trumpet player, and still have trumpet playing in your life, how easy is it do that? Our kid has been in it for nearly 4 years now- lessons, band, jazz, various day and sleep-away camps, and more, likely, in high school. I'm worried that the trumpet might be an instrument that demands a minimum level of practice; and if for some reason you can't maintain that because of other things in your life, you lose a lot of your skill. E.g., I had classical piano lessons for 8 yrs, and as an adult, I can pick up and sight read new material or get back to old; or take a class, a workshop, and, to be sure, I'm just talking about being an amateur and nothing more. But I don't feel like it'd be a huge slog to really get back into it and derive enjoyment. For instance, when I retire and/or have more time, I can imagine taking lessons again, and not feeling that I've lost everything because I stopped frequent practice years ago.

tl;DR: can trumpet still be an important part of your life if you don't practice daily, say? Can it be something you pick back up again after a years' long hiatus and still derive enjoyment from it?
