He says if a child is acting out in a way that is concerning and affects your child, the best thing to do is to seek out their parent and alert them to the situation.
And while not all parents may have a reasonable response, Coulson says it’s the best bet to resolve things. He suggests telling them:
“I’m sorry to bother you. It seems that your child is a little upset. He/she has been hurting some of the kids in the playground. I thought I should just come over and let you know.”
He says you’re likely to get a positive reaction and resolution with this course of action, far more than if you had disciplined the child and that parent was left looking for the person who had frightened their little one.
If a scenario arises where you do need to take matters into your own hands, Coulson says it’s important to remember that discipline doesn’t mean punishment and consequence. Instead, if you can approach the situation, speaking to the child kindly and suggesting positive ways to behave, you shouldn’t find yourself in an altercation with another parent over your actions.
However, there will be some situations where the best course of action is to leave. If a parent and their child both appear aggressive or anti-social, removing yourself and your child from the space may be the safest choice.
