No kids here, but similar in that I remember sessions of long focus, and being able to do them repeatedly, for multiple days in a row. I typically can't do that as much now. Perhaps more to the point, I can't do them on demand. I do still have periods of 'focused flow', and they're great, but they just 'happen'. But... I never could just turn them on/off in the past either - they just happened far more frequently. I predict you'll have more, just not as frequently as you used to. :) FWIW, many of the things I used to have to spend long periods of focus on are now simple/common libraries that just didn't exist 30 years ago. Or, if they existed, there wasn't any convenient way of discovering them. So I find my productivity is still comparatively high, even with fewer number of flow states.
