@belyse Not sure about the other things but when i comes to art just let him do whatever he wants. He just sounds stubborn. I'd just give him some room and he'll grow out of most of this.
@ambience00 We had the same issue.
Solution? We just let me son stay up later....everyone was much happier.
Many years later he's a good kid, does well in school, lots of friends etc.
No harm was done.
