Sound like your son has already developed some leadership charactoristic.  Unless he is at risk of getting injured or emotionally upset, perhaps give him some skills to help adjudicate when they are fighting.  Like a couple of phrases like, let's forget about this and go play cars etc. Or lt's sit down and talk about it.  Or just ask him to get the teacher.

Congratulations on raising a boy with such a strong sense of justice.

your son sounds as thow he has a lovely little heart, theres nothing he can do when his little friends figth, children of that age get over it very quickley trust me i have had 5 myself and 8 grandchildren, and allow your little one to say superhero he will come away from saying it when hes read trust me just dont comment when he saids it, love elizabeth100

hey Rachel, if you go to my homepage and click on the TRIBES article I wrote under Libby24 account there are a few things that are great to teach him and maybe get your school to start to do. Tribes is now a recongnised system that alot of school are taking onboard now. My sons teacher from last year was our school rep to go to Albany to learn more about it. Its really good for at home as well.

But basicly it teaches the kids to learn to say stop to thing they dont like and ways to get heard.

The other way is to get him to back away and tell a teacher or parent there so he isnt in the cross fire. I have had to teach Alex this as he is very against real violence. (cartoons he loves. LOL)

Good luck

IF YOUR SON IS TRYING TO STOP FIGHTS AT 4YRS OF AGE, HE SOUNDS LIKE HE IS MORE MATURE THAN HIS CLASSMATES.  I WOULD EXPLAIN TO HIM THAT IT IS GOOD OF HIM TO TRY TO STOP THEM FIGHTING BUT, IT WOULD BE BETTER TO LET A TEACHER STOP THEM AS HE MAY GET HURT HIMSELF.  MAYBE THE FRIENDS WHO ARE FIGHTING JUST BOTH WANT TO BE HIS FRIEND AND DON'T KNOW HOW TO SHARE HIS FRIENDSHIP.  YOU HAVE A VERY SPECIAL LITTLE BOY WHO CARES ENOUGH ABOUT HIS FRIENDS TO STOP THEIR FIGHTING.
