You don’t mention his father. Is he trying to get attention because he lacks a male role model?
If that’s the case, find someone to fill the role. You might even find a fireman that would be willing to visit once a week or something, if you have no male relatives that can do it.
Spend more time with extended family that has males.
I was hoping to find some kind of video on YouTube where someone who 'learned his lesson the hard way' would warn children. Yes, I am considering a tour of a burn ward.
