When my kids got obsessed with something that wholesome, I’d just let them have at it. I never complained about how much time or effort they put into it.
I always figured that doing stuff like that would be keeping them out of getting into far worse stuff. I knew where they were and what they were doing and far be it from me to look a gift horse in the mouth.
I also wanted to let them learn the rewards that come from that kind of effort.
Yes, true... much better that they do the wholesome things... :-)
