If you have more than one child - it's easy; have one hit the other and the other hit them back. If you only have one child - then the parent must be the 'other' person.
If they are teens.....it's more difficult to do this.
Most children do NOT understand anything about comprehension until they are in high school.
My parents usually would allow us to make our own mistakes and if we got hurt in the process then lesson learned. You can always sit them down and talk to them about what they are doing and explain the consequences or even find a video or picture on the internet that shows them the consequences. Hope this helps!
