1) this is unacceptable.... that the Bully is continuing this behavior
2) It is the school's responsibility... to deal with it...
3) Your Priority... is your child... and making sure he is not bullied
4) it does not matter that your son is 'dismissive' about it... he is young... a child needs the PARENTAL help, to stop it. If this happened in an office among adults at work... it would not be tolerated... and you would do something about it...
5) it is not your child's response to it, that dictates what should be done... because... BULLYING... is just NOT appropriate... no matter what... so stop it.
6) You document everything, and write letters... and follow-up.
7) That Bully's parents... ALSO has to be dealt with, by the school... and they need to do things which will correct the child... and the whole scenario...
8) The TEACHER, is also responsible for following up... AND talking the entire class, about PROPER behavior and saying that Bullying is NOT ALLOWED, and that there will be consequences for it.
That is what ALL my daughter's Teachers did... whenever there was a Bully in class.
9) At the same time, you parent your child... and teach him right and wrong... that ANY Bullying, is wrong.. and that he tell you and the Teacher... right away. You teach your child, how to handle Bullying... this is your role for your child at home...
10) Again, it does not matter... how "patient"/confident/tough your son is about it all... because, "Bullying" is simply WRONG... and your son, needs to KNOW... what wrong behavior is... and that it is not allowed.
Teach him to not play with Bullies, to speak up and say "STOP... ", to Tell the Teacher, to go and play with someone else... and to speak up with any wrongdoing...
11) you also teach him... what a 'friend' is... that friends do NOT do things like this... and if someone is doing that to them... then he needs to tell you... and that child is not a friend... or can harm him. That ANYTIME another child or adult harms him... this is simply WRONG etc.
The show 20/20, last week had an episode on Bullying... and they said it is EPIDEMIC in the United States... and it is a really big problem... among kids, of all ages. So.. you TEACH your child about it... and REPORT it to the school... and DEMAND they properly, handle it and the Bullying kid.
Your son was already head-butted by that Bully... I would not tolerate this any longer. I would DEMAND the school do something about it...
My Daughter, was bullied before... in Preschool and in 1st Grade. I did NOT tolerate it nor just sit back and say "oh well.. my daughter is dismissive about it.... " etc. No... my daughter KNEW it was wrong, she told me and the Teacher.. and I dealt with it swiftly and right away... and they reprimanded the child... who it turned out, was a chronic Bully... and to other kids. The school, needed parents like me... who gave them proof and in writing...and FORMALLY complained... so that they could then deal with that child and her parents.
So... you NEED to do something about it.
all the best,
Susan
