In moderation, right?! It’s hard to say exactly what is “best” but I certainly relate to some points. I had recently changed my own behavior where my kids (2 boys) would be fighting, I used to intervene, but more recently I let them go. I feel that they are defining boundaries this way. Fighting and wrestling are part of a natural play, as long as it’s not out of pure anger or spite. I struggle in other areas for sure and try to “govern” their behavior, but this is giving me a new perspective.
