It is a common thing for kids to play together and in the process go violent.

Kids may fight or beat one another while playing together although such doesn't last and they get to play together once again.

But in certain situations, some parents become unsettled and intervene in favour of their kids which may in turn cause a misunderstanding between parents if not properly handled.

Parents, have you ever intervene on behalf of your kids?
Also, what is the best thing to do if situations like that arise?
