My son was in elementary school at the time his bullying occurred.  Luckily, it was not badly hurt or physically injured.  An older child in his class used to push him around and call him names, mostly after school during dismissal.  My son didn't tell me immediately I found out one day after questioning him walking home and he broke down and told me that this bigger kid keeps bothering him.  His teachers didn't do anything when he told them, it wasn't until I spoke to the dean and assistant principal that it was made an issue.  The young man was "spoken too" and then removed from my son's class, after which the bullying deceased.  My son is now 11 and in the 6th grade.  This happened when he was in the 4th grade.  Thankfully, he was not physically hurt but emotionally it affected him.  Now he is more open and sticks up for himself in order to defend himself from inconsiderate children.  My sons case is small but every incident of bullying leads to bigger issues and all incidents count.  Stop it at its root before it festers and causes more issues.
