Signs of bullying in Kindergarten

Due to the fact the children are still learning how to navigate emotional regulation, emerging cognitive function and developing the social skills necessary to resolve conflicts – therefore aggressive behavior is extremely common at this age. This may look like name calling, pushing or taking a toy away from someone else. This behavior however, is to achieve a need of some sort and happen because the child does have the tools or skills to acquire that need in a constructive manner (using their words, asking an adult for help, etc.) 

“Bullying, which is marked by an intent to harm, imbalance of power, and repetition, is different from general aggression”

While it is completely normal to see some aggressive behaviours from kindergarten aged children, there’s a line where it becomes problematic. There are key difference between what is considered age appropriate aggression and bullying and it is important to understand the difference.  To clarify, bullying is a series of acts inflicted by one child on another child, that are intended to be harmful. These harmful acts are a way for the bully to gain or assert power over a peer.  Some signs of bullying in kindergarten are, physical (hitting, hurting), verbal (name calling, degrading) and social (social exclusion). 

The effects of bullying in kindergarten 

Although children in kindergarten can’t fully understand the effects that their words and behaviours have on other children, that does not change the fact that for the child on the receiving end, the impact is devastating.  Consequently, these impacts typically result in significant behavioural changes in young people.

Behavioural changes to look out for: 

  • Loss of appetite
  • Frequent, unexplained stomach aches
  • Significant changes in mood (lethargic, melancholy, more sad than usual)
  • Difficulty sleeping/nightmares 
  • Separation anxiety  
  • Lost or broken personal items (ripped clothes, etc.)
  • Showing sudden or unexplained aggression towards parents or siblings

Ultimately, supporting positive interactions with others is the best way to help children who are demonstrating aggressive or harmful behaviours. For example, helping them to be more mindful about how they make others feel, or using kinder words with their peers is a great place to start!
